For instance, Organix makes a product called RePeet, which is made from waste from the cattle industry.
Fox Farm has earned a reputation for manufacturing products that contain earth-friendly ingredients, though some might have a large carbon footprint due to the amount of travel required to bring products in from across the globe.
If I could only recommend one variety of premixed potting soil, without question, it would be their Ocean Forest mix.
It is OMRI listed and contains all the perfect ingredients to make plants happy, plus they’re more sustainable than a lot of other potting mix ingredients out there.
For sustainable fertilizer, you can combine blood meal (to supply nitrogen), bone meal (for phosphorus), and kelp meal (to add potassium).
Don’t feel frustrated with trying to find the perfect sustainable, organic potting mix. Life is about compromises, so just pick the best one you can.
Choosing a Potting Mix
Before we jump into choosing a commercial potting mix, I want to point out that premixed potting mediums are a relatively recent development.

People have been creating their own mediums for centuries and you should feel empowered to do the same if it suits your situation.
That said, there’s nothing wrong with picking up a potting mix online or from the store. Many of them are carefully formulated to make your plants absolutely thrive.
The potting mix you choose will need to be selected based on the plant it will be supporting.
Remember, there is no one-size-fits-all potting mix. However, there are lots of excellent options out there that will suit a wide variety of plants.
Also, don’t be afraid to think of a commercial potting mix as a starting point.
Use it as a base and then amend heavily it to make it perfect for your plant. Here are the most common types that you’ll see:
Cactus Mix
Cactus mix is made to be extremely well-draining and not very water-retentive.
It won’t have much, if any, organic matter. Ingredients usually include sand, lava rock, perlite, pumice, grit, and gravel. It’s best for plants that need little water and have shallow roots.
Cactus potting soils are ideal for succulents, cacti, and even Mediterranean herbs like oregano, sage, and thyme. It’s also an excellent choice for starting most seeds.
If you work in some compost and peat (or a peat alternative), it’s also good for many epiphytes like hoyas and peperomias.
Grab a one-and-a-half-cubic-foot bag of Tank’s Pro Cactus & Succulent mix at Arbico Organics.
Orchid Mix
Orchid mixes are made to allow tons of air to circulate around the roots of your plant.
They usually include lots of chunky materials such as bark, moss, and coco coir. In addition to using it to pot orchids, it’s an excellent medium for growing most types of epiphytes.
Standard potting mixes are made to accommodate most houseplants. They usually combine compost, perlite, vermiculite, and moss.
These mixes work for just about any type of plant except cacti and succulents. However, I almost always amend mine a little to suit the specific plant that I’m working with.
Photo by Kristine Lofgren.
Every species has unique needs, so you’ll need to do some research to determine exactly what will suit yours the best.
But broadly, I like to mix in lots of bark and rice hulls, along with some worm castings, for any variety of epiphyte except orchids.
That means pothos, hoyas, monsteras, ficus species, and philodendrons. Typically, I mix two parts bark, two parts potting soil, and one part rice hulls with just a dash of worm castings.
For ferns, calatheas, and alocasias, I add two parts compost to two parts potting soil, a dash of worm castings, and one part moss.
I just use the stuff that’s growing on the trees in my yard to keep it ultra-sustainable, but you can buy non-peat moss as well.
The Right Container Material
I wish there was just one perfect container material out there and we could all just use that for our houseplants and not have to worry about anything else, but that’s not the case.
If you want to keep your plants alive, there are a few things you have to do: give them light, feed them now and then, and – of course – water them.
Watering seems pretty straightforward to me. You fill a jug or can, bring it over to your plant, and dump the liquid in, right? Not much room to run into trouble.
But despite that, I’ve managed to find trouble so many times, and I can pretty much guarantee that you have as well.
Fortunately there’s a different way, and it can help take the guesswork out of figuring out how much to provide. That means healthier, happier plants.
Plus, it can protect your floors and shelves (and books!) from overzealous watering.
Up ahead, here’s what we’ll discuss to help you figure out the art of bottom watering.
What Is Bottom Watering?
To put it simply, bottom watering (sometimes called reverse watering) is giving your plant’s roots hydration from the bottom up.
Instead of dumping liquid onto the top of the soil of your container plants, you allow the soil to soak it up into its roots from the drainage holes in the bottom of the pot.
This isn’t the same thing as wick watering. That’s when you use a central container like a bucket to slowly wick moisture via ropes into nearby containers.
It’s a super handy skill to have in your back pocket if you travel a lot, but not what we’ll be covering here.
Why Use This Technique?
I warped my hardwood floors when I spilled an entire watering can once.
But beyond architectural disasters, I’ve also managed to drown my plants, and to chronically underwater them.
And don’t tell me you haven’t overwatered to the point where the drainage plate overflows and you’re frantically trying to find a towel before it runs everywhere… just me? I don’t think so!
Let’s not even discuss the time I decided it was a brilliant idea to put a bunch of houseplants on my wire shelves above a collection of leather bound books…
Okay, so it’s pretty straightforward to understand, but why would you want to water from the bottom? Doesn’t pouring it on the top work perfectly well?
Yes, there is nothing wrong with top watering (aside from occasional mishaps), but there are times when it isn’t ideal. For instance, some plants suffer if they have moisture on their leaves.
It’s hard to avoid splashes and mistakes altogether, even when you’re careful.
For lush, moist arrangements like the fairy garden, woodland hike, and island getaway themes, moss is a perfect ground cover between plants.
Its texture and color variations are perfect for replicating hills and valleys.
The fern is great for creating mini landscapes. The fronds add height, to give the illusion of a canopy of foliage.
Southwest Scene
Astride a palomino on a pebbly, parched riverbed, cacti and succulents dot the landscape as you pass.
Use this vision to fashion a Southwest scene so realistic you can feel the sun on your back as you ride.
A Southwest scene with succulents in an open planter.
For a Southwest scene, use plants like:
This arrangement is perfect for an open terrrarium. Mist occasionally.
For even more mini garden projects to create at home, we suggest checking out the book “Creative Terrariums: 33 Modern Mini-Gardens for Your Home” by Enid G. Svymbersky.
Decorative sand is optional for surface decorations, and miniature figurines are an optional decorative addition to help set the scene.
Modeling clay is ideal to have on hand to create a base for containers that are likely to roll.
Newspaper is an excellent asset for any gardening craft project. I like to keep it on hand to spread out before I get started, to protect my work surface.
It’s important to set up your terrarium with the appropriate soil.
African violet potting mix is a good choice if this is what you’ll be growing, or cactus mixes that are light and loose work well for southwestern favorites like succulents and cacti.
Sphagnum moss is perfect for layering, and it comes in handy for surface planting as well.
Instructions:
Choose a theme and select appropriate plants (see below) and accessories.
Wash container, tools, pebbles/stones, and figurines with mild dish soap and water before assembly. Rinse thoroughly and dry with paper towels.
Spread newspaper over your work surface.
Decide whether you will use your vessel horizontally or vertically.
Cover the bottom of the terrarium with a layer of pebbles followed by an inch of activated charcoal.
Cover activated charcoal with a layer of sphagnum moss, then add two inches of appropriate potting soil.
Decide where you want your plants, and use your spoon to make a small hole for your first one.
Grasp the plant gently with tweezers or fingers. Trim off all but an inch of root length, and place it into the hole, covering the roots, and tamping the soil down with the pencil or chopstick.
Be sure to place them so that they do not touch the sides of the container, and do not reach the lid.
Continue planting until all specimens are in the soil.
If desired, fill in areas between plants with pieces of sphagnum moss, tamping gently.
Add decorative sand, pebbles, stones, and figurines to define your chosen theme.
Mist foliage and soil lightly and shut the lid securely for closed arrangements.
Place away from direct sunlight.
It’s important to keep an eye on your new miniature garden. If a closed container becomes completely fogged, you may have overwatered.
Yours might not produce more than a fruit or two each year, but each juicy reward is far more exciting than plucking a thousand lemons off of an outdoor citrus.
But even if you don’t ever see any fruit, they’re beautiful plants in their own right. Depending on the species you choose, citrus can grow anywhere from four to 10 feet tall indoors.
You have lots of options, so choose one that you’ll actually use the fruit from when it appears. Just be sure to give them tons and tons of sun. Even better, take them out to your patio in the summer.
If you’re a fan of sweet lemons, a Meyer lemon (Citrus x meyeri) might be the way to go.
A close relative of the corn plant, dragon trees (Dracaena draco) grow to about six feet tall indoors, with attractive strappy foliage.
Give them just about any level of light – as long as it isn’t exceedingly dim, they’ll put on a show.
The leaves can have a range of colors, including pink and red or even multicolor stripes.
9. False Banana
As delightful indoors as out, the false banana tree (Ensete ventricosum) doesn’t produce edible bananas, but it does grow some pretty impressive green and red leaves. They’re huge!
Each individual leaf can be up to six feet long – that’s a lot of drama packed into one houseplant.
If you put one in your yard the plants can grow to 20 feet tall, but indoors they stay closer to six feet in height.
Make this tall plant yours by snatching a four-inch pot at Home Depot.
10. Ficus Alii
While not one of the most common houseplants, ficus alii (Ficus maclellandii) is worth hunting down.
Also known as banana leaf figs, these plants are much easier to care for than their weeping and fiddle-leaf cousins.
The long, banana-shaped leaves won’t fall as readily as those of its cousins either. Just place it in bright, indirect light, and watch it grow up to 10 feet tall.
You knew there would have to be a fiddle-leaf fig (Ficus lyrata) on this list, right?
And I know I just mentioned that it can be a bit finicky.
But these plants remain a perpetual favorite because it’s hard to match those Jurassic-looking leaves when it comes to making an architectural statement in your space.
While they aren’t super fast growers, they can stretch to your ceiling – and beyond! – if they receive good light.
Despite what you may have read, they can handle some direct morning light and they’ll be better for it.
For a three- to four-foot tree in a plain or decorative pot, or a four- to five-, five- to six-, or six- to seven-foot-tree, pay Fast Growing Trees a visit.
I need to preface this by saying that I am completely in love with fishtail palms (Caryota spp.).
The leaves are so unique and elegant, it’s like having a bright green betta fish swimming around in your living room.
So this is not an unbiased description. To be totally honest, they’re a little fussy, but don’t write them off.
Fishtail palms can grow over 12 feet tall indoors and they make a huge statement with all that pretty foliage.
I’ll level with you, though – they do much better if you can put them outdoors for part of the year. At the very least, give them direct morning light but protect them from the afternoon sun.
Green is lovely, but sometimes a little color is what you need. If that’s the case, check out the Hawaiian ti (Cordyline fruticosa).
The violet, red, or pink leaves are a stand-out against all the greenery you often find in houseplants, though there are green cultivars, too.
While these tree-like shrubs can grow taller outdoors, indoors they stop at about 10 feet tall. Just be sure to give them bright, filtered light. These shouldn’t be left in a dark corner.
Lady ferns (Athyrium filix-femina) might not immediately jump to mind when you’re thinking of tall houseplants, but they can grow up to five feet tall.
Add a foot-deep container and a plant stand, and you’re stretching to the ceiling.
They thrive in low light and average humidity, so these aren’t fussy ferns.
If you’re hoping to bring a forest vibe into your space, invite this lady into your abode.
Up for the challenge of growing this persnickety palm? It’s worth the effort. Perfect Plants Nursery carries plants in 10-inch pots.
16. Money Tree
Money trees (Pachira aquatica) are popular houseplants because they don’t ask for much from you in terms of maintenance, but they offer up a lot in terms of display.
They often come with three braided stems, and they’re always topped with glossy, large, feather-shaped leaves.
Feeling adventurous? Natal mahogany trees (Trichilia emetica) are gorgeous but they’re a bit fussy. I don’t tell you that to scare you off but to prepare you.
Photo via Alamy.
The feather-shaped leaves covering a seven-foot-tall plant make a real statement in the home, so those who aren’t afraid of a gardening challenge shouldn’t hesitate.
This species needs moderate light and lots of moisture, plus warm temperatures.
18. Norfolk Pine
Outdoors, Norfolk pines (Araucaria heterophylla) can reach hundreds of feet in height, but indoors, they stay closer to 10 feet tall when mature.
These lovely miniature Christmas trees bring an evergreen forest vibe to your interior. They’re happiest in bright, direct light and are sensitive to overwatering.
If you love palms but want something easier to care for than, say, a majesty palm, parlor palms (Chamaedorea elegans) are where it’s at.
They can reach up to 12 feet tall but stay smaller if you keep the roots constrained.
They aren’t demanding about humidity and if you forget to water one week it won’t turn into a crumbly mess, unlike some palms I could mention (looking at you, areca!).
Rubber trees (Ficus elastica or F. robusta) live up to their name.
While you often see them as smaller specimens, given a big pot and several hours of direct light each day, yours can grow into a 10-foot-tall tree-like plant with those characteristic, huge, fleshy leaves.
You have lots of options when choosing the perfect one for your decor, from those with solid-colored green leaves to highly variegated multicolored leaves.
‘Ruby’ is a variegated cultivar that features new growth in a bright ruby shade with magenta midribs.
As they age, the color changes – green leaves are striped with white and light pink. Be sure to give this cultivar some bright light to preserve the variegation.
Fast Growing Trees carries ‘Ruby’ in six-inch as well as one- and three-gallon nursery pots, as well as several different three-gallon decorative pot options.
For a dramatic statement, you’ll be hard-pressed to find a specimen that’s more impressive than a big, healthy tree philodendron (Thaumatophyllum bipinnatifidum, syn. Philodendron selloum and P. bipinnatifidum).
These plants can grow up to 10 feet tall with massive, elegant leaves that are unmistakable – though it’s worth noting that they can take 20 years to reach maturity.
The secret to success with this plant is to flush the soil regularly to remove any salt buildup. Tree philodendrons don’t like salt one bit.
Triangle ficuses (Ficus triangularis) are named for their triangle-shaped leaves, which come in solid and variegated types.
While good old F. benjamina and F. lyrata have a reputation for needing a bit of babying, this particular ficus isn’t going to drop its leaves whenever so much as a slight breeze moves through the room.
This slow grower reaches up to eight feet in height, but it takes some time. Keep your plant in bright, indirect light for the best growth.
24. Umbrella Tree
Umbrella trees (Schefflera actinophylla) are incredibly forgiving.
I had one that moved with me across thousands of miles, was left in my office for weeks in a dark corner before I remembered it, had a visiting cat pee in its pot, and fell off my patio.
None of these misadventures even caused it to flinch. It’s still cooking after 35 years.
They grow up to 10 feet tall indoors and all they want is some indirect light and a little water now and then. You can find them with solid or variegated foliage.
Weeping figs (Ficus benjamina) are fabulous despite their reputation for being demanding. In reality, these plants are pretty resilient and forgiving.
You just need to understand that they can and will drop their leaves at the merest breath of change.
If you even think about moving yours to another part of the room, expect this houseplant to drop those leaves in a huff. But don’t worry, they’ll come back – it’s just the tree’s coping mechanism. We all get stressed out sometimes, right?
Indoors, these figs can grow up to 10 feet tall if you let them.
Tall houseplants bring height and texture to your interior decor. Plus, they make a much bigger statement than your average pothos or African violet.
Better yet, they don’t demand more care than smaller houseplants to keep them happy and healthy. Find the right light conditions, supply the water and food they need, and you’re off to the races.

The houseplant goodness doesn’t stop here. We have a bunch of other guides to help you bring even more nature indoors, starting with these:
Humidity is conducive to lush foliar growth. Water at the soil level to maintain even moisture, and mist the foliage occasionally during the growing season.
You’ll find the pot dries out more slowly during winter dormancy, and misting is not necessary during non-growth periods.
Watch out for high-nitrogen fertilizer as your plant may grow like crazy. Choose a well-balanced liquid houseplant food instead, and apply it monthly from spring through fall.
Try training a climbing species around a rich, earthy moss pole. Direct any visible aerial roots down toward the soil, or snip them off. They’re for adhering to trees in the species’ native jungle habitat.
Also called devil’s ivy, pothos (Epipremnum aureum) is known for being easy to grow and for producing exceptionally long vines.
There are numerous types of pothos, but a feature they all share is the heart-shaped leaves on trailing vines.
Imagine them wrapped around an entire room, softening the edges of stately oak bookshelves or sleek lighted curio cabinets.
The foliage may be green or green variegated with white or yellow. In low-light conditions, variegation may be less pronounced and leaves may shade to all green.
Like a philodendron, this climber is a fast-grower that’s easy to take care of, thriving equally well in soil or water. It, too, has aerial roots for climbing jungle trees.
These are also useful for training vines to grow upwards on moss poles, instead of hanging downwards.
Thick, sword-like, upright leaves that reach one to four feet tall characterize the slow-growing snake plant, aka mother-in-law’s tongue.
It is a very forgiving plant, because it’s used to a hardscrabble life in its native jungle habitat, where the soil is poor and space is scarce.
Formerly known as Sansevieria trifasciata, this plant was recently reclassified as Dracaena trifasciata. You may see either botanical name on plant tags.
Low-maintenance and easy to grow, it has a high tolerance for very bright as well as very dim light, being root bound in a small pot, and dry potting medium.
The best medium to grow it in is a cactus and succulent product that is formulated for exceptional drainage.
Allow the soil to dry out completely between waterings, and occasionally wipe the leaves down with a soft cloth to rid them of dust.
During winter dormancy they don’t need more than a splash of water every few weeks. Take care not to overwater as this is likely to cause rotting.
Fertilizer is not required, but if you choose to use it, dilute a liquid houseplant food to half strength and apply it in the spring or summer.
Cultivars range in color from light to dark green, white mottled, or gold edged. They do best in the 65 to 85°F range. Temperatures that are too cold may cause brown scarring.
The easy-care, fast-growing tropical spider plant (Chlorophytum comosum) has green, variegated green and white, or green and yellow leaves that grow in a clumping form, arching gracefully like spray from a water fountain.
It looks most attractive in a hanging pot.
Cultural requirements include well-draining potting soil, a room temperature of 65 to 75°F, and water when the top inch of soil dries out. Provide a pot with adequate drainage and avoid oversaturation that can lead to rotting.
It’s not necessary to fertilize, as too much can burn tender leaf tips. If you choose to feed, use gentle worm compost tea. Cold drafts are another cause of browning tips, so be sure to avoid them.
Choose green cultivars for low-light placements. Variegated types do best in moderate to bright indirect light, and will shade to green in dim settings.
A unique feature is the wire-like stems of about two feet in length that descend from the foliage to sprout baby “plantlets,” aka “spiderettes.”
These are more likely to appear in brighter light conditions, and are easily snipped to root and grow in pots of their own.
Plants that fit snugly in their pots are more likely to produce plantlets, so don’t repot large plants until you see roots poking from the drainage holes, indicating that they are becoming root bound and need more space.
The bright, glossy green leaves of Swedish ivy (Plectranthus verticillatus) have crenate, or round-toothed margins. Trailing to lengths of two to three feet, this fast grower is well-suited to hanging baskets.
It prefers organically-rich, evenly moist potting medium that drains well, and likes to fit snugly in its pot.
Provide a temperate setting between 65 and 75°F during the day, and 60°F or above at night. It’s used to high humidity in its native tropical habitat, but tolerates typical indoor levels well.
Swedish ivy may become leggy in low light. If it is getting scraggly, pinch off the growing tip just above a leaf node at the length of your choice to promote branching growth.
Water when the top inch of soil is dry. Feed monthly with a well-balanced liquid or granular plant food diluted to half strength.
Also known as monstera or split-leaf philodendron, the tropical Swiss cheese plant (Monstera deliciosa) has giant leaves that may measure 18 inches or more in length, with “fenestrations” or openings that appear as deep leaf edge serration and holes.
The leaves start out whole, and in low light, may remain whole. And while unlikely indoors, a mature plant may bear white, lily-like flowers followed by fruit.
This climber puts out aerial roots that readily cling to a moss pole. An overabundance of these above-soil roots may mean it’s time to repot. You can curb aggressive growth by snipping these roots off for a more compact specimen.
Choose a temperate 60 to 80°F location and prevent exposure to temperatures below 50°F. If possible, maintain ambient humidity at or above 40 percent. You can raise the moisture level by grouping plants, or misting the foliage occasionally.
Periodically wipe the leaves with a soft cloth to rid them of dust that attracts pests.
Striped green and silver ovate leaves with purple undersides are a key feature of the fast-growing wandering dude (Tradescantia zebrina).
It’s also known as inch plant because the leaves are spaced one inch apart from each other, as well as spiderwort.
The best room temperature for this trailing beauty is between 70 and 80°F, and never lower than 50°F.
It prefers bright indirect light, where its variegated colors are the showiest, but tolerates lower light placements as well.
Cultivate in organically-rich, moisture-retentive, well-draining potting medium. Water when the top one to two inches feel dry, and avoid both letting it dry out completely, and oversaturation.
As a tropical, wandering dude loves humidity. If your home is especially dry, under 30 percent humidity, you can increase the ambient moisture around plants by grouping them together, or using a humidifier.
Misting with a spritz-bottle is an option, but beware – persistently dim and damp conditions may result in fungal growth.
Fertilize monthly during spring and summer with worm compost tea to reduce the risk of over-feeding and burning foliage, while boosting soil nutrients.
If your plant gets too leggy, pinch it back just above a leaf node to encourage lateral growth. In the spring, you can cut back up to one-third of the foliage for a rejuvenating prune, if desired.
Tropical ZZ plant (Zamioculcas zamiifolia)is tough as nails, with pairs of leathery, elliptical green leaves and thick stems. It averages two to three feet tall indoors, but is capable of soaring to five feet.
Able to store water and sustain itself through a drought, your ZZ is not going to quit on you if you occasionally forget to give it a drink. Bright indirect sunlight is the best, but ZZ performs admirably in low-light and beneath fluorescent bulbs.
You’ll need a temperate location in the range of 60 to 75°F, and always above 45°F. Avoid drafts and increase the humidity if your home is especially dry.
Use a well-draining pot and avoid oversaturation. Let the soil dry out completely before watering again. The fleshy rhizomes are built to store water, and can easily rot if they are too wet.
Low-light plants grow slowly. Prune as desired, just above a pair of leaves, for a more compact form.
With 25 attractive options from which to choose, you are well on your way to establishing a low-light arrangement of greenery that will bring your indoor decor to life.
When selecting plants, remember that green varieties yield the best results under low-light conditions. You can try more colorful cultivars, but they may fail to produce a showy display in dim rooms.
Flowering, a rare occurrence for some of the options described above, is unlikely in low light as well.
If you live in a temperate zone, you can move your low-light houseplants outdoors for the summer. This is a great rejuvenator that restores their vibrant colors and boosts their overall health.
Here are five tips to review before I leave you to start shopping for exciting new plants that are going to liven up even the dimmest areas of your home:
Use pots that drain well to prevent excess moisture buildup, a leading cause of pest and disease infestation.
Water sparingly in winter, when plants are generally at rest.
Always water before fertilizing to avoid burning foliage and roots. And if you see a white, salt-like mineral buildup on the soil surface, foliage, and pot, flush the pot with water, empty and rinse drip pans, switch to distilled water, and don’t wet the leaves.
Avoiding wetting the foliage of low-light plants not only helps to reduce mineral buildup, it reduces the risk of fungal infection as well.
Keep the leaves of your new favorites clean and shiny by wiping them gently with a soft cloth every few months.

My houseplants are an important part of my indoor decor, providing texture, color, and life to almost every room in my home.
In spite of my careful ministrations – providing the right amount of water, some careful pruning when needed, and appropriate lighting – once in a while a houseplant comes down with a disease and I need to go into rescue mode.
If you grow houseplants long enough, it’s likely something you’ll experience, too – perhaps you already have, and that’s why you’re here.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
I think the hardest part of managing plant disease is figuring out what the heck you’re dealing with in the first place.
When you know what disease is affecting your houseplant, you can formulate a plan to manage it. In some cases this might be pretty simple and in others an extreme challenge.
This guide is going to go over 11 common and not-so-common problems that can infect the plants that we generally like to grow in our homes. I’ll also provide treatment options where possible.
Here are the baddies we’ll talk about:
We are going to focus purely on diseases in this guide, but it’s important to note that there are also some environmental disorders that can cause disease-like symptoms.
Brown leaf margins and tips on some species can be caused by fluoride, chlorine, or other chemicals in the water. Dry, hot air is another common cause of discolored foliage.
Wilting foliage is often a result of over- or underwatering, and leaf drop can happen if the environmental conditions change suddenly – such as moving your houseplant into a location with more or less light.
Here are 11 diseases that can afflict many common houseplant species:
1. Anthracnose
Anthracnose is the broad term for a variety of diseases caused by fungi in the Colletotrichum and Gloeosporium genera. These pathogens attack hundreds of different plant species, both indoors and out.
The symptoms depend entirely on the species affected. On Dracaena and Dieffenbachia species, for example, the disease causes circular lesions on the leaves and stems.
Anthracnose on orchids typically causes the leaves to turn brown and yellow before dying off.
When the disease shows up, the best way to treat it is with a biological fungicide that contains Bacillus subtilis.
This beneficial bacteria will outcompete the bad pathogens, disrupting their reproductive cycle so they can’t proliferate.
Arbico Organics carries a product called CEASE that contains this powerful bacteria in gallon and two-and-a-half-gallon containers.
Follow the manufacturer’s directions for treating houseplants, and apply once a week until symptoms stop advancing.
2. Bacterial Leaf Spot
Spots on houseplant leaves can be caused by fungi or bacteria. When bacteria is the culprit, it’s a pathogen in the Erwinia, Pseudomonas, or Xanthomonas genera.
Depending on the species of bacteria that is infecting the plant, it might just be a few leaves that are impacted or it could be the entire specimen.
Symptoms generally appear as lots of little spots or v-shaped lesions that spread and turn the entire leaf brown.
The spots are dark, ranging from brown to black, and they can be dry or appear water-soaked. They may or may not have yellow margins.
When a leaf turns entirely brown and collapses, it will be mushy and stinky. If you’ve ever smelled the water in a vase after it has been left for several days, it smells a lot like that.
Usually, the spots appear in between the veins but not on the veins themselves. Most develop on or near the margins of the leaves, but they can start at the stems or in the middle of the leaves as well.
You can prune off any symptomatic leaves, but if the entire plant is impacted, you’ll need to toss it out because there is no cure for bacterial leaf spot.
3. Bacterial Wilt
While bacterial issues aren’t extremely common on houseplants Ralstonia solanacearum (formerly Pseudomonas solanacearum) can infect over 200 different species, causing the foliage to droop and wilt.
When you see the plant wilting, you might check the soil, thinking it needs some water, only to find that it has ample moisture.
Sometimes bacterial wilt starts as one section of the specimen wilting; other times, the whole plant starts to show symptoms. The pathogen thrives in warm, humid conditions.
Unless the houseplant is one that you really love and can’t replace, it’s usually best to toss it out if it becomes infected.
If you want to try and save your plant, you will need to remove it from its container, clean the pot with hot, soapy water, and then wipe it with isopropyl alcohol.
Remove all of the soil from the roots by brushing it away and then rinsing it off using lukewarm water.
Repot in fresh soil in the cleaned container and then treat the plant with a bactericide.
Follow the manufacturer’s directions carefully as some of these can be toxic if not handled appropriately.
A product called Procidic uses the power of citric acid to kill bacteria is appropriate.
Fungal leaf spot is a broad term that encompasses a range of species, symptoms, and causal pathogens. As the name suggests, the symptoms involve spots on the foliage.
Most fungi travel in water, so they need moisture to spread and reproduce.
As part of our preventive measures, we need to focus on keeping water where it belongs, which is in the soil, and not where it can cause problems, like sitting on the leaves and stems.
That means providing enough space so your houseplants have good air circulation and watering at the soil level or using the bottom watering method. Take care not to overwater or spray humidity-loving species too often.
The other part of the equation is protecting the plant so that it isn’t injured, which creates an opening for pathogens to enter through.
Plants in areas that have lots of traffic are often injured by people walking by. Too much pruning or pests can also create openings for pathogens. Excessive fertilization can also leave houseplants exposed to pathogens.
Let’s talk about some of the most common types of fungal leaf spots.
Myrothecium leaf spot is caused by the fungus Myrothecium roridum. It can infect species in the Anthurium, Pilea, and Aglaonema genera, as well as many others.
It usually causes dark spots on the foliage, but it can also cause crown and stem rot on some plants.
Fusarium fungi can also cause leaf spots, especially on Dracaenaspecies.
The same fungus that is famous for destroying tons and tons of strawberries every year and improving the flavor of wine, Botrytis cinerea, can also wreak havoc on houseplants.
It’s massively destructive in greenhouses.
The pathogen enters plant tissue via openings like injuries, faded flowers, or pruning cuts. Overfertilized specimens in moist conditions are also susceptible to infection.
Prevention includes removing any debris from around the plant. Those occasional dead leaves? Don’t let them hang out on the soil surface.
Try not to allow houseplants to become damaged by pets or people brushing up against them, and don’t overfertilize or overwater.
If your houseplant is infected, you’ll typically see brown, soggy spots on the foliage and stems. As the disease progresses, you might see gray, fuzzy fungal growth.
Many strains of this disease have become resistant to fungicides, so it helps to rotate your treatments.
Buy a couple of different products that use different methods of treatment. A product that contains Bacillus amyloliquefaciens strain F727, B. subtilis, potassium bicarbonate, Streptomyces strain K61, or citric acid can be effective, especially when rotated.
There are even products developed just to address this disease; that’s how big of a problem it can be.
If you want to try a targeted product like that, head to Arbico Organics and pick up some BotryStop WP, which targets botrytis with the beneficial fungus Ulocladium oudemansii (U3 strain).
Watch for a white or gray powdery-looking coating on the foliage.
You can rub it off with a moist cloth or your finger, but this only helps you diagnose the problem, not get rid of it, because the fungus is systemic, not isolated to the surface of the plant tissue.
There are dozens of different pathogens that cause powdery mildew and many of them are species-specific.
If you find that your houseplant is infected, isolate it to avoid spreading the problem. Fortunately, powdery mildew is one of the easiest diseases to treat and get rid of.
You can use all kinds of treatments, like milk and baking soda, or fungicides like sulfur, copper, and neem oil.
Root and crown rot is a generic term for any disease that causes infection and rotting in the roots and crown area.
Most of the time, it’s caused by fungal pathogens, but bacteria and oomycetes can cause rot, too.
In houseplants, rot is typically caused by pathogens in the Alternaria, Armillaria, Cylindrocladium, Fusarium, Phytophthora, Pythium, Rhizoctonia, and Sclerotinia genera.
Without exception, rot needs moist conditions to be able to take hold.
Overwatering and soggy soil is a sure-fire way to invite root rot, while watering from overhead so moisture can pool on the leaves or stems can lead to crown rot.
High humidity and crowding can invite these pathogens as well.
When crown rot is present, you can see it. There will be areas on the plant that will be mushy and black or brown. They might be slimy and stinky, too.
Root rot is a little harder to identify because it happens under the soil where you can’t see it until the symptoms appear on the aboveground parts.
These symptoms will generally start as yellowing or browning of the leaves and leaf drop, and possibly stunted growth. If you dig down, you’ll find brown or black, mushy roots that might smell rotten.
I like to treat crown and root rot with a biofungicide that attacks a broad number of pathogens. My go-to is Mycostop, which contains a beneficial bacteria called Streptomyces Strain K61.
This bacteria is derived from sphagnum peat moss and is effective against every species listed above.
Pick up Mycostop in five- or 25-gram packets at Arbico Organics, but be sure you use it immediately after opening because it rapidly loses effectiveness as the beneficial bacteria is alive.
Depending on the product, you’ll want to apply it every two weeks or so until new, symptomless growth develops.
For root rot, soak the soil and if there are symptoms on the aboveground parts, spray the leaves and stems. Honestly, I would always treat both the soil and the foliage and stems just to be safe.
Additionally, in the case of root rot, it helps tremendously to remove the plant from the pot and brush the soil away before trimming any dead roots at least half an inch into healthy growth.
Then, spray the roots directly with Mycostop.
Clean the container thoroughly with hot soapy water and repot in fresh, clean soil.
Rust is a common fungal problem that affects many plants growing outdoors, and while it’s much less common in houseplants, it’s not unheard of. It’s particularly common on cacti.
There are species-specific fungi that cause aloe rust (Phakopsora pachyrhizi) and begonia rust (Coleosporium solidagin) for example.
There are over 5,000 species of fungi that can cause rust, so many houseplant favorites are susceptible.
The disease spreads through water, so avoid overwatering or watering from overhead and allowing the foliage to remain damp. Don’t crowd plants or keep them in an area that’s too humid, either.
As the name suggests, the disease looks like your plant is rusting, with orange streaks or spots on the stems and foliage.
Fortunately, it’s pretty easy to treat with a product that contains B. subtilis, like CEASE, which we discussed above.
10. Stem Canker
Stem canker is another generic term for diseases that cause lesions or rot at the base of the stem. Typically, it looks like a dark, sunken area either on one side or encircling the stem.
In most houseplants, fungi in the Alternaria, Lasiodiplodia, Neofusiccocum, Phomopsis, and Sclerotinia genera cause this disease.
As with most fungi, these pathogens need moisture to thrive, so crowded, overwatered specimens are most susceptible.
If the plant has multiple stems, you can prune out the infected ones. But if there is just one main trunk or stem and it’s infected, there isn’t much you can do.
You can try treating it with any fungicide, but chances are the plant will need to be disposed of.
11. Viruses
There are so many different viruses that cause symptoms in their hosts including tobacco mosaic virus (TMV), impatiens necrotic spot virus (INSV), and dasheen mosaic virus (DsMV).
Most are species-specific, meaning they only attack one or a few related species of plants.
Generally, most viruses are spread by insects or on infected plant material and tools.
The symptoms vary depending on the type of virus, but usually you’ll see yellow or cream mottling and discoloration on the foliage.
As with most viruses that make humans sick, there is often no treatment that can completely cure the problem. In humans, we often let the disease run its course.
You can do the same with plants, but the disease will never go away. Plus, you run the risk of infecting other specimens in your collection.
But if you aren’t particularly worried about spread, viruses usually won’t kill the plant, and so long as you keep it healthy, it can survive for years. Otherwise, bag it and toss it in the trash.
Show Diseases the Door
Diseases are a part of gardening, they will come and go, despite your best efforts. But as you gain experience, you start to learn how to avoid them.
Keep your plants appropriately watered, well-spaced, always use clean tools, and you won’t have to worry about diseases as much as gardeners who don’t practice good sanitation.
Are you dealing with diseases in your houseplants? Tell us what you’re facing or what symptoms you’re seeing in the comments section below and maybe we can help you narrow down the problem.
I love my houseplants. Virtually every room in my home has at least two or three different specimens. It feels like a bit of the great outdoors under the protection of four walls and a roof.
Whether you’re overrun by houseplants like I am or you just have one individual specimen that you’re particularly proud of, houseplants change the space.
But when we bring houseplants into our homes, we sometimes invite problems like pests, as well.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
I’m guessing that you’re here because you suspect or know that there is some kind of creepy critter crawling on your orchid, philodendron, or succulent.
Do you want to know the secret to ridding your houseplants of pest problems?
No, it’s not a big old vat of insecticide, it’s being able to identify the specific pest that’s causing the issue.
With a solid identification, you can then take steps to address it and prevent future infestations.
There are 11 common pests that feed on houseplants and we’ll help you identify each of them and give you some tips about how to deal with an infestation.
Here’s the list:
11 Common Houseplant Pests
In this guide, we won’t talk much about “occasional invaders” like ants, pillbugs, millipedes, slugs, and spiders.
These critters can hitch a ride on plants that are brought in from outdoors but they don’t thrive in an indoor environment. They will typically die off on their own.
Still, it helps to double- and triple-check your plants when you bring them in from outside.
With all of these pests, early identification is vital.
Make it a habit to examine your plants when you water them. Look at the top and undersides of the leaves, along the stems, and at the soil level.
And it goes without saying that healthy plants can better withstand an infestation than those that are stressed from inappropriate environmental conditions.
That means watering, feeding and keeping them in the right light exposure for the type.
Let’s start with one of the most common pests indoors and out:
1. Aphids
I’m willing to bet that if you grow plants long enough, you will come across aphids either indoors or out at some point.
Aphids are tiny sapsucking insects that feed on almost every popular houseplant out there.
There are many different species, most commonly green aphids (Myzus persicae), green peach aphids (M. persicae), and brown ambrosia (Uroleucon ambrosiae).
Some, like melon aphids (Aphis gossypii) are especially bad because they breed all year long in warm locations, like inside your home.
Regardless of the species, they can reproduce fast. One day you’re looking at just a small issue and the next you’re facing a devastating infestation.
Aphids cause leaf yellowing and distortion like curling and wilting. They can also spread diseases and kill off developing flowers. If there are enough of them, they can cause stunted growth or even kill the plant.
They leave behind a sticky substance called honeydew, and this can attract sooty mold.
In addition to these symptoms, you might see the insects themselves. They’re small, but they generally cluster together on the undersides of leaves, and on the stems, especially where the leaves meet the stems.
If you catch it early on, you can usually address the problem with nothing stronger than water. Isolate the plant and spray off the aphids with a strong stream of water.
Do this every few days until you don’t see any left on the plant. Keep the plant isolated for a few more days to be sure they’re all gone and you can move it out of isolation.
2. Caterpillars
Caterpillars are the larvae of a variety of different pest species.
None of them thrive indoors, so these are the pests that will sneak in occasionally and then die off because they can’t complete their life cycle in your home.
If you see any, just put on some gloves, pluck them off, and drown them in soapy water. Not much to worry about.
The exception is if you see worm-like critters in the soil. These grubs can infest the soil and feed on the roots of your plants.
Treat the soil with a spinosad-based pesticide or one that contains the beneficial fungus Beauveria bassiana. Do this every few weeks until you don’t see any additional pests.
I’ve had success with Bonide’s Super Insecticidal Soap, which contains spinosad and is available in quart-sized ready-to-use spray bottles.
Fungus gnats are one of my least favorite pests, but they’re also one of the least problematic.
I just hate how they fly around, tricking me into thinking they’re tiny mosquitos, and landing on my books while I read so they end up smashed between the pages.
I realize this is a petty complaint when there are pests out there that will kill your prize variegated monstera in a heartbeat. But something about them just drives me up the wall.
Fungus gnats are tiny flying insects in the Orfelia and Bradysia genera. They are small, around one-sixteenth to half an inch long, and they look similar to mosquitos, but they don’t bite humans.
They feed on fungi and other decomposing matter in the soil, not on live plant material.
So the adults won’t hurt your plants, but they will fly around being annoying. To justify my unreasonable hatred, the larvae can be a problem. They feed on plant roots, causing stunted growth and leaving the houseplant vulnerable to disease.
Fungus gnats can reproduce all year round with overlapping generations, so populations can build up quickly.
If you see the adults flying around, put some yellow sticky traps in the soil and reduce the amount of water you’re offering your houseplants.
Fungus gnats love moist soil, so if your plant can handle it, water less often with more water.
Or try the bottom watering method. If you can keep the surface of the soil dry while providing moisture, as happens with bottom watering, it can help to reduce populations dramatically.
Between the two, it should be enough to reduce or eliminate fungus gnats.
If that doesn’t work, you can add a product that contains Bacillus thuringiensis sbp. israelensis (Bti).
You can also use beneficial nematodes in the soil to kill the larvae. Specifically, choose Steinernema feltiae nematodes.
Until populations build up dramatically, they can be hard to spot because they are flat and immobile so they almost blend in with the stems.
Plus, they like to hide in nooks and crannies so you can’t see them even if you do know what to look for.
The adults are oval and flat, without wings. Most have a waxy coating, but some don’t. The coating can be clear, brown, or white, and the pests themselves can be anywhere from cream to black in color.
Citrus mealybugs (Planococcus citri) are the most common species found on houseplants. They’re covered in a fluffy, white, waxy coating.
Before you bring any new plant into your home, quarantine it for a week or two and examine it carefully and repeatedly. Look for both the pests themselves and their cottony white egg sacs.
Mealybugs use their sucking mouthparts to feed on sap of the plant, causing symptoms like yellowing or speckled foliage, aborted flower buds, and stunted growth.
They also leave behind a sticky substance called honeydew. That’s a nice way of saying that they poop out the excess sugars that they consume. This attracts sooty mold, which is a whole other problem.
I’m not going to lie, mealybugs can be difficult to eliminate.
Because they hide in protected areas on the plant, and thanks to the waxy protective coating, they can be hard to find and kill.
You can wipe the pests off with a butter knife, spray them off with a strong stream of water, or wipe them with a cotton swab dipped in isopropyl alcohol to remove their protective coating.
On larger plants, you might need to prune out heavily infested areas, since it’s unlikely you’ll be able to find and kill all the pests.
Bag and dispose of the pruned parts to avoid spreading the pests to other specimens in your houseplant collection.
If you have a large infestation, scrape or wash off as many mealybugs as you can. Then, spray the plant with insecticidal soap.
Make sure to get in all the nooks and crannies to find the hiders, because the soap needs to come in contact with the pests to kill them.
No, not spider mites, we’ll come to those later. We’re talking about the microscopic arachnids cyclamen mites (Steneotarsonemus pallidus) and broad mites (Polyphagotarsonemus latus).
Mite damage on a strawberry plant.
Both types of mite hide in the folds of leaves and on stems, feeding on the plant’s sap.
As they feed, they extract chlorophyll and cause the plant to look sickly and pale, or take on a bronze hue.
New growth might be slow or non-existent, the foliage may curl or be distorted, and any flowers or fruits will abort.
The extra bad news is that you have no way to know they’re around until symptoms show up.
So long as you act quickly you should be able to save your plant.
The most effective way to rid the plant of these tiny mites is to submerge it, pot, soil, and all, in a bath of 110°F water for 15 seconds.
This won’t kill most houseplants, but don’t try it on a precious, tender specimen.
You can also treat the plant with a miticide or insecticidal soap. Saturate the houseplant and soil once every two weeks until new, healthy growth emerges.
7. Scale Insects
The first time I saw scale on a houseplant, I thought my specimen just had some weird bumps on the stem. I shrugged and went on with my week.
Next time I looked, the bumps had increased in number and it started to occur to me that maybe there was something wrong with my coffee plant.
Scale insects are more common on outdoor plants than those grown indoors, but if they can sneak inside on a specimen that you bring home from the store or that has been outside for the summer, they will.
There are a few species that will feed on houseplants, with hemispherical (Saissetia coffea) brown soft scale (Coccus hesperidum), fern scale (Pinnaspis aspidistrae), and lecanium scale (Parthenolecanium spp.) being the most common.
Their appearance can vary depending on the species, with some having soft bodies and others having hard shells.
Most are brown but they can be white to black. All are oval and somewhat flattened or round, and usually under an eighth of an inch long.
The females don’t move much. In most species, they lose their legs and stay put, which can make them easy to mistake for a growth or something other than pests.
Even those species that remain mobile tend to hunker down, develop a protective waxy coating, and live out the rest of their lives without moving.
To get rid of scale, dip a toothbrush or cotton swab in isopropyl alcohol and wipe it over the pests.
You can also gently scrape them off with a butterknife or wash the plant with soapy water, but if you do this, be sure to protect the soil so that it doesn’t get wet.
Spider mites are super common houseplant pests. These tiny little arachnids are common in dry, warm environments, which is often what we find in our homes.
There are several species that you can find indoors, but the two-spotted spider mite (Tetranychus urticae) is most common.
Closely related to ticks, they resemble spiders but in miniature, with eight legs and an oval body that is under 1/50th of an inch in diameter.
The two-spotted mite is reddish-orange, but other species can be black, brown, or cream.
You probably won’t spot the arachnids themselves, unless you use a magnifying glass. More than likely, it will be the fine webbing that they weave that you’ll notice first.
The pests will also cause the leaves to turn yellow or develop yellow stippling as they use their sucking mouthparts to feed.
Because they thrive in dry climates, you can go a long way toward avoiding them if you keep the soil of your plant moist, if appropriate, and by wiping the leaves down with a damp cloth once a week. This helps remove dust anyway, so it’s a good habit to get into.
If your plant has spider mites, try isolating it and spraying off the pests with a strong stream of lukewarm water. If the infestation is severe, water won’t be sufficient, you’ll need to break out the insecticides.
Before using any product, be sure it’s appropriate for your particular houseplant species. If appropriate, insecticidal soap or a miticide is your best bet.
Follow the manufacturer’s directions for houseplants and keep treating at least once or twice after all signs of the pests are gone.
In plants that are heavily infested and more than half of the leaves are symptomatic, you might be best just discarding the plant. It can be hard to address a very serious infestation.
Before we dive in, just know that springtails – hexapods in the Collembola class – aren’t commonly found on houseplants.
These elongated brown, black, gray, or white pests look a little like fleas, and can jump in much the same manner, but they don’t hang out on humans or animals.
Instead, they prefer moist conditions and soil with lots of organic matter. If you have terrariums, the chances are good you’ll come across them.
Springtails are detrivores, which means they eat decaying plant matter in the soil. Technically, they feed on the fungi and bacteria that feed on the decaying organic matter.
The important point is that they don’t feed on your live plants, so they are more of a nuisance than a big problem.
If you’re finding them on houseplants, the solution is easy: water less often. Let the soil dry out a bit more between watering. Most plants can survive with less water than you think and the springtails will die off or move onto greener pastures.
When it comes to terrariums, hobbyists will intentionally introduce these critters because they can be a positive part of a healthy enclosed environment, so just let them be.
10. Thrips
Thrips (order Thysanoptera) aren’t as common as aphids or spider mites, but like many other critters on this list, they can piggyback on a plant brought in from outside or from the grower’s greenhouse.
Thrips leave stippled silvery markings as they use their sucking mouthparts to feed on the foliage of plants.
These long, narrow black, cream, or brown insects are minuscule, rarely larger than one millimeter in length.
The silvery speckling on the foliage is as a result of the enzymes the pests inject as they feed, but you might also see scarring and yellow halos, which come from egg laying.
They also leave black fecal matter behind as they move around.
While thrips won’t usually kill a houseplant, they can weaken the specimen and can also spread disease.
As with spider mites, you can help limit these pests by wiping your plant with a damp cloth once a week, keeping the soil moist, and raising the humidity in the area.
Trapping can help control them, as can many insecticides including neem oil and spinosad.
Bonide Captain Jack’s Deadbug Brew is a spinosad-based insecticide, and you can purchase it in 32-ounce ready-to-use or hose end, or 16- or 32-ounce concentrate at Arbico Organics.
If you’ve ever walked past one of your houseplants and saw an explosion of flying bugs, those would have been whiteflies.
Whiteflies aren’t the most common houseplant pests, but they aren’t unheard of. They are often found in greenhouses.
Damage is limited if the population remains small, but if numbers increase, these pests can drain your plant of energy and cause the foliage to fall off.
Whiteflies are insects in the Aleyrodidae family and are closely related to mealybugs and aphids.
Like those relatives, they use their sucking mouthparts to feed on the sap in the plant. As they do, the foliage might turn yellow or have yellow speckles.
As the damage worsens, the leaves will die and fall off the plant. Whiteflies also excrete honeydew, which results in a sticky substance that covers the foliage.
They can also spread diseases. Control can be a challenge because whiteflies can quickly become immune to pesticides. If you see any eggs, prune off the host leaf immediately.
Isolate and spray your plant with a strong stream of lukewarm water to knock the adults, juveniles, and eggs off.
A product that contains the beneficial fungus Beauveria bassiana can also be highly effective against these little pests.
We’ve all been there. One day everything looks just fine with your houseplants and the next you’re battling an infestation that seems determined to spread.
This guide should set you on the path to eliminating the problem so you can enjoy your indoor garden once again.
What kind of pests are you facing? Have you dealt with infestations before? Let us know in the comments section below.
I always take my houseplants outside during the summer months. I have way too many of them, and it starts to feel a bit crowded in my home come April.
My annual spring cleaning involves shifting many of my houseplants onto the patio to enjoy the warm weather outdoors.
And then summer passes all too quickly, and it’s time to move them all back inside. But after spending months outdoors, if you don’t give your beloved plants the right transition, they might lose their leaves or even die.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
Transitioning a plant back indoors after spending the summer outside isn’t all that difficult, it just takes some forward planning and a little time.
We’ll give you all the information you should know for success, coming right up. Here’s what we’ll cover:
As with many things in life, timing is everything. So let’s sort that out first.
When to Move Your Plants
Every species is different, but most species commonly grown as houseplants need to come inside before the air temperatures drop below 45°F.
Some tropical varieties are extremely sensitive to cold. Species like bird of paradise (Strelitzia spp.) should be brought indoors before the lows reach 55°F, for example.
Because the process takes a week or two, you’ll need to keep an eye on the forecast and plan ahead.
If your area tends to be unpredictable, just plan to start this process in early October or late September to be safe.
Preparation
You can’t just grab your plants and bring them indoors. Whether you realize it or not, your home is typically much darker than even a covered patio.
Unless you have a sunroom with glass walls and ceilings, you need to acclimate them to the lower light conditions.
Before you do that, check, double-check, and triple-check your plants for pests.
Look for sticky honeydew coating the leaves, spots of black sooty mold, tiny white flies, or bumps that can be scraped off the leaves or stem.
Look under the leaves and on the stem under leaves, in particular. That’s where the bugs like to hide.
If you see any pests, spray them off with a blast of water or scrape them off, in the case of scale. You can also treat the plant with insecticidal soap.
Visit our guides to aphids, scale, and whiteflies to learn more about these common houseplant pests.
Heavily infested specimens might need to be disposed of, or at least quarantined until you can resolve the situation. Otherwise, you run the risk of the pests infesting every plant in your home.
I also like to flush the soil and rinse the leaves and stems with water before bringing the plants inside.
This can help remove any pests that are hiding in the soil. To do this, just saturate the soil until water is running out of the drainage holes at the bottom of the pot and allow it to run out for a minute or so.
Then, let the soil drain completely, emptying out the saucer or catchment pot as needed.
Alternatively, set the pot in a sink full of water to submerge it to flush out any insects.
Don’t flush the soil using either technique for species that require dry soil, like succulents or cacti as it will likely take too long to dry and you run the risk of root rot.
You should also check for other hitchhikers in addition to the pests mentioned above. In the past I’ve had lizards and frogs hiding out in my containers. Watch for snakes, spiders, and small rodents, as well. Wipe the bottom of the pot since spiders seem to like that area in particular.
Next, remove any yellowing or dead foliage and any spent flowers.
If you need to repot, now is a good time. If you see roots circling the surface perimeter of the pot or coming out of the drainage holes, it’s definitely time for an upgrade or time to trim back the roots a little.
If you do decide to repot, remove the plant from the container, gently loosen up the roots and brush away the soil.
Place a thin layer of potting medium in the bottom of the container so the plant is sitting at the same height it was originally. Set the plant in the container and fill in around the root ball with potting soil.
Don’t reuse your old soil. I know it’s tempting and I’ve done it a few times myself.
But potting soil becomes depleted of nutrients and compacted over time, meaning air and water can’t move through it. Use fresh potting soil and toss the old stuff into your garden, assuming your plant is pest and disease-free.
Cacti and succulents do best in a light, loose mixture made formulated specifically for these types of plants. A majority of species are happy in a standard, water-retentive, loamy potting mix.
Something like De La-Tanks soil mix is the perfect mixture of organic compost, coco coir, pumice, and fertilizer.
It’s available in quart, eight-quart, and 16-quart bags at Arbico Organics.
Moving Indoors
If you’ve ever hardened off a plant before taking it outdoors, the process for transitioning your houseplants back indoors is the same.
Bring the plant inside and put it in the spot where you intend to keep it. Leave it there for an hour and then take it back outside.
The next day add a half hour to an hour. Add another 30 to 60 minutes the next day. Keep adding time indoors each day for at least a week, but preferably two.
Of course, if the temperature drops suddenly, it’s better to bring your plants inside too quickly than to leave them outside in the cold.
If you do have a sunroom, you’ll still want to transition the plants gradually to the indoor conditions, but you can do it more quickly.
Ongoing Care
It’s entirely possible that, despite your efforts, your plants will still drop a few leaves. Don’t worry, this is totally normal.
Many species respond to an environmental change by dropping their leaves. Trim off any leaves that turn brown or yellow.
However, if the plant drops a majority of its leaves or begins to grow leggy, with long internodes (parts of the stem between each node), it’s a sign that the plant isn’t receiving enough light.
In that case, you’ll want to move the plant to a brighter spot or give it supplemental lighting.
Most plants will need significantly less moisture than they do when they are situated outside during the growing season.
For most species, you should allow the soil surface to dry out between watering.
Houseplants enjoy a summer vacation outdoors as much as the rest of us, but unlike you and me, they need special care when moving from the patio to the living room.
What kind of houseplants are you growing? Have they been outdoors during the summer? Let us know your set up in the comments section below.
Now that you’ve got the know-how to move your plants indoors in the winter, you might be looking for some additional houseplant care tips. If so, we have some guides that could help, like these:
In many ways, your home is a controlled environment, similar to other forms of indoor agriculture.
Indoor gardeners are able to ensure proper soil moisture, light conditions, and temperature for the plants that grow in our homes.
It is also important to supply proper nutrition for your houseplants, as they require macro- and micronutrients just like any other plant.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
Plants living in your home likely grow in relatively small pots compared to those growing outdoors in the garden, and the nutrients in the soil can become depleted quite easily.
In this article, you will learn the basics of plant nutrition, fortifying houseplant soil, fertilizing your flora while watering, and how to identify possible nutrient deficiencies.
Here’s what we’ll cover:
Nutrients that Plants Need
Plants require nutrients for basic biological functions, just like any other organism.
They are able to biosynthesize sugars, fats, and proteins – however, they can’t make mineral nutrients.
Mineral nutrients are separated into two basic categories: macro- and micronutrients.
Macronutrients
There are three nutrients that plants need the most, called primary macronutrients – these are nitrogen (N), phosphorus (P), and potassium (K).
Store-bought fertilizers are typically marked by a series of three numbers. A common label is 10-10-10. These numbers describe the relative weight percentage of nitrogen, phosphates, and potassium – often noted with the abbreviation “NPK.”
Nitrogen is essential for the biosynthesis of proteins, and it is a central component of chlorophyll, the green pigment that facilitates photosynthesis. Fertilizers with relatively high nitrogen content can be utilized to encourage rapid growth and foliage development.
Phosphorus is needed for photosynthesis and energy transfer. Growers may use fertilizer with high phosphorus levels for young specimens to promote root development, and later for flower, fruit, and seed formation.
Plants use potassium to mobilize water and nutrients throughout their vasculature, as well as for the activation of many enzymes.
Fertilizers high in potassium are often used to help plants with their water utilization. This can include mitigating drought or helping plants with their internal water pressure.
The application of primary macronutrients by growers can vary depending on the species of plant and its growth stage.
There are also three secondary macronutrients required in smaller amounts. These are calcium, magnesium, and sulfur.
Calcium is essential for maintaining the structure of cell walls, protecting the plant from external stressors. Magnesium and sulfur are involved in chlorophyll synthesis, which is essential for photosynthesis.
For my houseplants, I typically try to avoid flowering and fruit development, as I grow most of my specimens for their foliage.
For this reason, I tend to use fertilizers that are not too high in phosphorus, with a greater emphasis on nitrogen.
If you see the middle number (phosphorus) increased compared to the first (nitrogen) and last (potassium) numbers on the label, I would usually avoid those fertilizers for foliage houseplants.
Instead, I would use that fertilizer for those houseplants that you want to encourage to flower.
Micronutrients
To survive and thrive, plants also need an array of other nutrients, albeit in much smaller quantities than the macronutrients. We call these micronutrients.
Essential micronutrients for plants include magnesium, boron, copper, iron, manganese, molybdenum, nickel, and zinc.
Make sure to select fertilizers that also include these micronutrients. In many cases, the first nutrient deficiencies to appear are as a result of a lack of micronutrients.
Fortifying Houseplant Soil
There are two main categories of fertilizer that you can use for your houseplants: slow release and fast release types.
Slow release fertilizers are used to fortify soils for longer periods of time, with a continuous supply of nutrients, whereas fast release fertilizers are for immediate uptake by the plant.
You can fortify your houseplant’s growing media by mixing slow release fertilizers into the soil. I do this whenever I repot a plant.
For most of my houseplants, I try to change the soil once a year, mixing in slow-release fertilizer while I’m at it.
Most organic fertilizers are slow release, as they consist of biological materials that take a while to break down. Organic fertilizers often naturally contain plenty of micronutrients, too.
I use organic all-purpose long-lasting, granulated fertilizers, such as Espoma Organic Garden-Tone and Dr. Earth Pure Gold.
Espoma Garden-Tone is labeled for use on vegetables, but with an NPK ratio of 3-4-4, it’s an excellent choice for houseplants. It also contains beneficial microbes to further enrich the soil.
Synthetic slow-release fertilizers tend to dissolve less quickly than organic products. Continuous release synthetic fertilizer typically comes in small, round capsules.
These are often blue or tan in color. When you are looking at these make sure you consult the label to ensure the product contains micronutrients.
When I’m repotting, and using brand new potting soil, I fortify the media with both synthetic and organic fertilizer.
I consult the label for each package, and apply a little less than half of the recommended amount for each. Together, both fertilizers combine for a near full dose of nutrients.
I like to err on the side of “less is more” when it comes to fertilizer application. You can always add more!
For my more sensitive plants, such as cacti or orchids, I apply very little fertilizer to the growing media, and generally use a liquid product.
Sometimes a houseplant might need its growing media to be replenished with nutrients, but it is not yet time to repot the plant, so it can be difficult to mix in slow-release fertilizer. It is times like this when I sprinkle some capsules or organic granules on the top of the soil.
After several months, you can tell when the synthetic capsules are spent as they appear to be deflated.
Once most of the capsules have been dissolved, I sprinkle more capsules or apply organic fertilizer to the top of the soil. This helps to boost the nutrient content of the media until it’s time to repot again.
You can also use plant food spikes. These are sticks of slow-release fertilizer that you stake into the potting soil.
I use Jobe’s Fertilizer Spikes for Houseplants, which have an NPK ratio of 13-4-5 and are available in packets of 30 via Amazon.
I usually prefer to mix fertilizer uniformly throughout the growing media.
For plants like succulents that require very little fertilizer, I will sometimes place a fertilizer spike into the potting medium while watering and remove it after a day or two, to give the plants a gentle boost.
As with any fertilizer, never exceed the dose recommended on the label.
Liquid Feeding
Water-soluble fertilizers are formulated to provide immediate nourishment to your plants.
A large majority of water-soluble fertilizers are synthetic. They come in powdered or liquid forms, both of which need to be dissolved or diluted in a container of water before pouring onto the soil. Often, these products are blue in color.
For both the liquid and powdered versions, follow the label for mixing a certain volume into your watering can.
I usually apply half the recommended amount, since I also fortify the soil with slow-release fertilizer.
A good option is Dr. Earth Pump and Grow All Purpose food. It comes in a convenient pump bottle and has an NPK ratio of 1-1-1.
I feed my houseplants while watering about once a month in the warmer months, and once, if at all, during the winter.
Many plants undergo a pause in growth during winter, which means they will not need as many nutrients in their water.
I also buy the powder instead of the liquid. I think it is more environmentally friendly, since I can get the “liquid” water from my tap at home.
Addressing Nutrient Deficiencies
Symptoms of nutrient deficiency can vary greatly depending on the specific plant species as well as the nutrient in question.
Often, when a plant is deficient in one nutrient, it is also deficient in several others, possibly confounding the symptomatology. Which in layman’s terms means it can be hard to know exactly which nutrient deficiency is causing the problem.
General symptoms of most nutrient deficiencies include yellowing of leaves, known as chlorosis, and stunted growth. When these symptoms persist despite adequate watering, sufficient light, and no evidence of pathogens or pests, it may be time to fertilize your plants.
Houseplants may be especially prone to iron chlorosis, which is the yellowing of leaves as a result of iron deficiency.
This is because many popular houseplants come from environments with acidic soils, and if the potting soil you use is too alkaline, it will inhibit the uptake of iron.
Iron deficiency is characterized by yellowing of leaf tissue except for the veins. You can supplement iron-deficient plants with a chelated iron product or blood meal.
If you suspect your houseplant soil is too alkaline, you can add sulfur products to make it more acidic. Or simply repot into a more suitable potting mix.
Make sure you research the species you are growing to check whether or not it requires acidic soil.
Houseplants are also especially prone to magnesium deficiency, as magnesium leaches from the soil with every watering.
To supplement this loss in magnesium, you can add about one teaspoon of Epsom salts into one gallon of water, and use this solution to water your houseplants a couple of times a year.
Has your previously perky, lush, and green houseplant suddenly turned sickly yellow and droopy, or are there brown areas on the foliage and dropping leaves?
Root rot is a common issue in houseplants. Because they’re grown in such small environments compared to what they’d experience in nature, they’re a lot more sensitive to extremes such as too much water. And too much water is a direct cause of root rot.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
Pretty much any species is susceptible to root rot, though some are more resilient than others.
Coming up, we’ll help you figure out if your plant has root rot and what to do about it.
Here’s what I’ll cover:
Managing Root Rot in Houseplants
Before we figure out how to identify it, let’s talk about what causes root rot.
Causes of Root Rot
There are two main causes of root rot. The first is an abiotic condition when there is so much water in the soil that the roots literally drown.
When the soil is oversaturated, the roots aren’t able to access enough oxygen, and they start to turn soft and mushy. Just like any other creature when it’s deprived of oxygen – the plant starts to die.
In addition, there are many different fungi and water molds (oomycetes) that can cause the problem, but Fusarium spp., Pythium spp., Phytophthora spp., Rhizoctonia spp. are the most common and attack the broadest range of plants.
All of these pathogens thrive in high moisture and can be spread via water, in contaminated soil, on contaminated tools, and by insects, particularly aphids. The pathogens enter the plant via damaged vascular tissue.
The pathogens aren’t airborne, but if you have a humid home or growing area, they can spread through the water droplets in the air.
Symptoms
The symptoms of this disease can vary depending on the species affected. But in general, you’ll see yellowing leaves, brown patches on the foliage, dropping leaves, and stunted growth.
The plant might be wilting even though the soil feels adequately moist.
The best way to tell if the disease is present is to remove the houseplant from its container and inspect the roots.
You’ll generally see brown, black, dark, soggy roots. Some of the tissue might be healthy but there will be distinct evidence of rotting areas.
In the case of large, woodier plants like some palms and Ficus species, the outer layer of the roots – known as the epidermis – might slough off, leaving the pale interior exposed.
You might also notice a bad odor. If you’ve ever sniffed the old water in a vase that has been holding cut flowers, you know the smell.
Prevention
Root rot is almost always preventable. One of the easiest ways to avoid it is to be cautious about how much and how you water.
Avoid overwatering by testing the soil with your finger or a moisture meter before you water.
Don’t rely on a watering schedule, since every species is different and will take up moisture differently depending on the temperature, any breezes in your space, or the relative humidity in your home.
Make sure every container you use has drainage holes. You can place a container with drainage inside a decorative pot, but be sure to empty it out 30 minutes after watering. The same applies if you use any sort of water-catching saucer.
Use a well-draining potting soil suitable for the species that you’re growing, and don’t put a layer of rocks or broken pottery at the base of the pot. This actually makes the problem worse, not better.
When you water, be sure to apply the water to the soil, not on the leaves. Or use the bottom watering technique.
Always use clean, fresh soil and wipe any tools or containers with a 10 percent bleach solution before pruning or potting up.
When you bring a new specimen home, isolate it for a week or two to make sure it doesn’t have any symptoms of disease to avoid spreading the pathogens to your other plants.
Finally, avoid stressing your plants. A stressed houseplant is more susceptible to pathogens present in the soil. Inappropriate light, drought, and pest problems can all cause stress.
Treatment
The first step in treatment is to remove the plant from the container and get rid of all the soil.
You might need to rinse the roots in a stream of lukewarm water, or it might just brush away if it isn’t oversaturated.
If you happen to catch a whiff of something unpleasant, sort of like the old water in a vase holding a bouquet of flowers, that’s a good indication of root rot.
When you have all the roots exposed, look them over carefully. If you find any that are black, soggy or broken, cut these off with a clean pair of scissors or clippers just a bit above where the damage ends. You want nothing left but clean, healthy roots.
Wipe the old container out with a 10 percent bleach solution.
Spray the roots with a fungicide formulated for root rot or a broad-spectrum fungicide. There are a lot of options on the market, but you don’t need to look for anything fancy. A classic choice is copper fungicide.
Another option is Actinovate AG, which contains the beneficial microbe Streptomyces lydicus WYEC 108.
That’s enough to treat a lot of plants repeatedly, so it’s ideal if you’re dealing with multiple specimens or just want to be sure you have something on hand.
After you have trimmed off all the rotten tissue and treated the roots, repot the specimen with fresh, clean potting soil. Continue to soak the soil with a fungicide according to the manufacturer’s directions until healthy new growth emerges.
Going forward, use a soil moisture meter and be especially careful not to overwater.
Resistant Species
If you really can’t stop overwatering your houseplants, either get an epiphytic species and mount it on wood or wire, or stick to growing air plants (Tillsandia spp.). It is almost impossible to overwater a mounted specimen!
In addition, there are a number of species that aren’t prone to this condition. These are some good choices:
Cast-Iron Plant
As their common name suggests, cast-iron plants (Aspidistra spp.) are tough. Really tough.
You’d have to absolutely drown this houseplant for a sustained period to kill a cast-iron plant.
The strap-like leaves come in various shades of green and can have beautiful variegation in the form of spots and or lines.
Cyperus species like umbrella sedge or papyrus plant (C. alternifolius) are extremely tolerant of wet feet.
They grow in swampy areas in the wild, so that should come as no surprise. If you’re a convicted overwaterer (raises hand), consider this palm-like species.
If you grow fuchsia (Fuchsia spp.) as houseplants, you’ll not only be treated to the gorgeous blossoms, but a specimen that will tolerate soggy conditions as well.
While they can technically suffer from root rot, you’d really have to make an effort.
Ficus
Many Ficus species are resistant to root rot, both from overwatering and from pathogens, but not all. Fiddle-leaf figs, for one, seem to be more prone than others in the genus.
My first experience with this disease was a fiddle-leaf fig that I overwatered for months before I realized what I’d done wrong.
It lost half of its leaves and needed some serious rehab, but it’s still with me and lovelier than ever after all these years.
But creeping figs (F. pumila), for example, won’t flinch at too much water.
Root rot is one of the more common problems when growing houseplants, but that doesn’t mean it has to cause trouble in your indoor garden.
As I said, you can largely avoid root rot if you take a few precautions. Even if it this disease does become an issue, you can treat it if you catch it early enough and save your plants from certain doom.
Are you struggling with root rot? What symptoms are you seeing? Let us know in the comments section below.
Another good reason for urgent repotting is if the container it’s growing in is much too large for the specimen.
Of course, even for species that tolerate being rootbound, there will come a time when you’ll eventually need to repot. I’ll provide some repotting tips for you at the end of the article.
But first you’ll want to learn what to look for as signs that you do indeed need to repot, so let’s learn more about these 17 houseplants that don’t mind being rootbound:
1. Alocasia
Our first selection is Alocasia, which doesn’t need frequent repotting.
Known for their supersized heart- or arrowhead-shaped leaves and high contrast coloration, alocasias (Alocasia spp.) are dramatic looking houseplants that will command your visual attention.
Alocasia.
When it comes to care, alocasias need bright, indirect light and moderate watering.
These striking houseplants don’t mind being slightly rootbound and can keep growing in the same container until roots start emerging from drainage holes.
Once you witness those emerging roots, or the potting medium is drying out too fast, it’s time to repot.
‘Polly’ is a hybrid cultivar that has glossy, dark green leaves with purple undersides and ruffled edges, and contrasting white to light green leaf veins. It reaches two feet tall and wide at maturity.
Next on our list is aloe vera, a succulent which thrives in rootbound conditions and shouldn’t be repotted often.
With long, tapering, fleshy leaves, Aloe vera is a staple in the DIY medicine chest because of the skin-soothing gel that is contained within its foliage.
Aloe vera.
Aloe vera needs six hours of direct sunlight per day to thrive, and should be watered when the top two to three inches of growing medium are dry.
When it comes to repotting aloe vera, it will only need to be transplanted every few years.
You can let it go somewhat potbound, but it may be time to repot when roots are poking through the drainage holes, or the specimen is top heavy and prone to falling over.
Have you been living without one of these succulents?
Amaryllis doesn’t need to be repotted frequently, it prefers rootbound conditions.
You may think of the flower amaryllis (Hippeastrum spp.) as something to be discarded after it’s done blooming, but it can certainly be kept as a houseplant for the long term. They can actually live for decades!
Amaryllis.
With showy blooms held on long, thick stems that emerge from large bulbs, amaryllis plants are right up there with poinsettias and Christmas cacti as “must have” living flora for the winter holidays.
Amaryllis thrives with six hours of direct sunlight per day and should be watered when the top few inches of the growing medium are dry.
Take care to use a houseplant watering can with a narrow spout to water only the growing medium, not the bulb.
This amaryllis kit comes in a burlap gift bag and includes a ‘Spartacus’ amaryllis bulb, a decorative white ceramic pot, complete instructions, and growing medium.
You’ll find it at the Daylily Nursery Store via Amazon.
This next selection, Chinese money plant, shouldn’t be repotted often. Instead, it should be allowed to grow in the same container until somewhat rootbound.
In the houseplant world, Chinese money plant(Pilea peperomiodes) is instantly recognizable – it has long, thin, arching stems, each of which bear a single, round green leaf, held like baubles on the plant.
Chinese money plant.
These cute green pileas are nontoxic, so they make a good fit for households with kids and pets.
Good care for Chinese money plants includes offering bright, indirect sunlight, and watering when the soil is dry half way down the growing medium.
Related to watermelon pilea aka aluminum plants, Chinese money plants don’t like to be repotted, so it’s better to allow them to become somewhat rootbound before transferring to new containers – approximately every two years.
Whether you’re drawn to these pileas for their perky appearance or their Feng Shui symbolism of wealth, you can bring home one of your own!
You’ll find a live Chinese money plant in a four-inch nursery pot available for purchase from the California Tropicals Store via Amazon.
5. Christmas Cactus
This next selection, the well-loved Christmas cactus, doesn’t require frequent repottings and grows well when rootbound.
Known for their bright blooms that appear during the dark months of the year Christmas and other holiday cacti (Schlumbergera spp.) make excellent, easy-care houseplants.
Provide Christmas cactus with bright, indirect light, and water when the top inch of the growing medium is dry.
As epiphytes, Christmas cacti don’t need a lot of growing medium for their root system and prefer to be slightly potbound. On average, holiday cacti should be repotted approximately every three years.
Want to add one of these to your home to liven up your holiday decor?
Our next selection, epiphyllum, grows better when rootbound and only repotted infrequently.
Jungle cacti like their relative the Christmas cactus, Epiphyllum houseplants produce large, showy flowers, and have long, flattened, succulent stems.
Also known as orchid cacti, epiphyllums are safe for households with pets and young children.
Epiphyllum.
Indoors, epiphyllums should be grown primarily in bright, indirect light, though a couple of hours of direct sun in the morning will please these succulents too, as long as you habituate them to direct exposure gradually.
Water when the top third of the growing medium is dry.
As epiphytes, epiphyllums only need small pots compared to the massive amounts of foliage they produce, and they don’t mind being rootbound.
Plan on repotting every five to seven years or when the specimen becomes unstable in its pot.
E. hookeri subsp.guatemalense, also known as “curly Sue” or “curly locks” is an epiphyllum with twisting and curling stems.
I’m an avowed epiphyllum fanatic and this is one of my personal favorites.
Like many succulents, this next houseplant on our list also prefers to be rootbound rather than undergoing frequent repottings. I’m talking about jade plant.
Jade plant.
Jade plant (Crassula ovata) is a classic among succulent houseplants.
With egg-shaped, bright green leaves, an upright growth habit, and stems that turn woody, mature specimens often resemble miniature trees.
Jade plant grows best in direct sun for part of the day, complemented by bright, indirect light, and the soil should be allowed to dry out almost completely between waterings.
Don’t repot your jade plant until it is cracking its container or until its foliage is so heavy that it’s tipping over – approximately every four to five years.
Do your other succulents need a little jade tree to watch over them?
Our next selection, kalanchoe, also favors rootbound conditions and shouldn’t be repotted often.
There are many different types of kalanchoes (Kalanchoe spp.) – but one thing these succulents have in common is that they don’t mind being snug in their containers.
But perhaps one of the most well-known is K. blossfeldiana, commonly known as florist’s kalanchoe or flaming Katy, a houseplant popular for its brightly colored flowers and fleshy green foliage.
Grow kalanchoes in bright, indirect light, and water when the soil is dry three to four inches down.
As noted, these succulents don’t mind being rootbound, but look for roots emerging from drainage holes as a sign that it’s time to repot.
‘Calandiva Red’ is a kalanchoe cultivar that has dark green foliage and red, double blooms.
These make great gifts for that special someone – and maybe that special someone is yourself!
Whether it’s a gift to give or a gift to get, you’ll find live specimens of ‘Calandiva Red’ kalanchoe in four-and-a-half-inch nursery pots, available for purchase from the Succulents Box Store via Amazon.
This next selection, lipstick vine, performs beautifully when allowed to become rootbound rather than repotting it frequently.
Nontoxic and related to African violets, lipstick vines (Aeschynanthus spp.) are epiphytes that have elliptical, green or variegated leaves, and reddish flowers that look like little tubes of lipstick.
Lipstick vine.
Lipstick vines grow best in bright, indirect light. Allow the top few inches of soil to dry between waterings.
These houseplants don’t require frequent repotting, usually every two to three years is sufficient. In fact, they actually produce more flowers when somewhat potbound.
Black pagoda plant (A. longicaulis) is a type of lipstick vine with gorgeously patterned foliage and orangish-red flowers.
Do you have just the perfect spot for a hanging basket with lipstick vines trailing down?
Speaking of flowers, keep this next selection rootbound rather than repotting it for a more floriferous hoya.
When picking a houseplant you often have to choose between either eye-catching foliage or showstopping blooms – but hoyas (Hoya spp.) give you both.
Hoya.
Safe for households with pets and small children, there are many, many different types of hoyas, and not all have the same light and water preferences.
But a good rule of thumb when you don’t know what kind you have is to offer bright, indirect light and to let the growing medium dry out completely between waterings.
Many Hoya species are epiphytes so they have small root systems, and they produce blooms more generously when rootbound. These are often grown in smallish pots compared to the large masses of foliage they produce, and only need to be repotted infrequently.
H. latifolia ‘Variegata’ (formerly known as H. macrophylla ‘Variegata’) is a beautiful hoya with large, thick, spear-shaped leaves, prominent veins, and outer variegation – that’s to say variegation on the margins of its leaves.
Need one of these to start off your hoya collection?
Our next selection, Norfolk Island pine, can be allowed to grow in rootbound conditions rather than repotting it to keep it from outgrowing our homes.
There aren’t many conifer trees that can grow happily indoors as houseplants, but Norfolk Island pines (Araucaria heterophylla) take to the indoor environment like superstars.
Norfolk Island pine.
With green needles and softly drooping branches, these pyramid-shaped trees can serve as stand-in Christmas trees, or create a stately presence in a large space.
These nontoxic trees will thrive with a few hours of direct sunlight, supplemented with bright, indirect light. Water when the top inch of the growing medium is dry.
Repotting your Norfolk Island pine may be a chore you should put off – by repotting less often, it’s possible to keep this tree – which outdoors, can grow to 200 feet tall! – at a manageable size.
These conifers make gorgeous living Christmas trees that you can decorate – with lightweight baubles only, please! – year after year.
Ready to bring one of these home for some holiday cheer?
Our next selection, Peperomia, is a genus with many indoor-friendly species that grow well when rootbound, and don’t need frequent repotting.
Peperomia houseplants come in many shapes and sizes, but most of them are known for their attractive, fleshy foliage.
Peperomia.
Peperomias thrive in bright, indirect light and need their growing medium to dry out slightly between waterings – the top inch of soil should be allowed to dry.
With small, fine roots, these nontoxic houseplants don’t require frequent repotting and it’s fine to let them get a little rootbound.
Once the potting medium starts to dry out too often, or you check the roots and they are filling up the pot, that’s a good sign that it’s time to repot.
Watermelon peperomia (P. argyreia) is a species of peperomia whose leaves are patterned with stripes reminiscent of those on a watermelon rind.
Do you have a home office or tabletop in need of some peperomia joy?
The next houseplant on our list, rex begonia, should be allowed to become rootbound to prevent transplant shock from repotting.
With brightly colored foliage, hypnotizing patterns, beguiling leaf shapes, and somewhat fussy care requirements, rex begonias (Begoniaxrex-cultorum) are often thought of as divas in the houseplant world.
Rex begonia.
These houseplants need very bright, indirect light and consistently moist soil, accompanied by excellent drainage.
Rex begonias don’t care for being repotted, so they should be allowed to grow in the same container until their roots fill their pot completely.
You can pull a plant out of its container to check for this – if any loose soil remains in the pot when you lift out the plant, it’s not time to repot yet.
Harmony’s ‘Love Potion’ is a cultivar that has green and purple leaves with splatters of white dots.
Ready to bring one of these fascinating rex begonias home?
Our next selection, snake plant, benefits from somewhat negligent care, which includes allowing it to become rootbound rather than repotting frequently.
If you want a live houseplant that will put up with being treated as part of the decor, snake plant (Dracaena spp.) makes a great option.
Snake plant.
With their long, leathery leaves, snake plants can get by with low light and very little water.
However, growth will be better if they are provided with bright, indirect light. The growing medium should be allowed to dry out almost completely between waterings.
Snake plants make excellent starter houseplants, and when it comes to repotting, they will happily keep growing in the same container until the overgrown roots cause it to crack.
You will need to refresh the growing medium every five years if you don’t repot sooner than that.
What’s better than one snake plant? A grouping of more than one!
This next selection, spider plant, is a resilient, adaptable option that remains happy and healthy when rootbound and infrequently repotted.
Spider plants (Chlorophytum comosum) are perhaps one of the most widely kept houseplants and are easy to recognize – they look like a pot of pale green or green and white grass.
Spider plant.
Mature specimens often have spiderettes extending from long thin stems, and they may be the quintessential hanging basket houseplants.
There’s a reason for their popularity – these nontoxic houseplants are supremely easy to care for.
Spider plants can be grown in bright, indirect or medium light and should be allowed to dry out somewhat between waterings. They are fairly adaptable to different watering routines, as long as you don’t overwater.
Growing thick white roots that gradually fill up their pots, there’s no need to repot spider plants until they are bursting out of their containers or until they start drying out too frequently.
In fact, being rootbound will encourage spider plants to produce spiderettes.
‘Ocean’ is a cultivated variety of spider plant that is more compact than the species plant, with leaves reaching eight to 12 inches long at maturity.
Don’t leave this trusty standby of the houseplant world off your wish list – there’s a reason they’re so popular!
This next option on our list, tree philodendron, is best kept somewhat rootbound to keep it from getting too big.
With large, green, lobed leaves, tree philodendron (Thaumatophyllum bipinnatifidum) is a giant of the jungles that will provide a tropical vibe when you bring one into your home.
Tree philodendron.
Tree philodendrons thrive in low light to bright, indirect light, and have moderate water needs.
These houseplants thrive with potbound roots, but you’ll need to refresh the potting soil periodically and the roots to keep it in check.
Our final selection, weeping fig, is a sensitive option that would rather be rootbound than repotted.
Often appearing with braided trunks or variegated foliage, weeping fig (Ficus benjamina) is another classic houseplant.
Weeping fig.
Thriving with bright, indirect sun and moderate watering, weeping figs don’t like changes – and repotting definitely counts as a change!
Weeping figs can be allowed to become rootbound, these shouldn’t be repotted until there are roots coming out of their drainage holes, or circling the surface of the soil.
With their lofty heights and lush foliage, these trees help brighten up corners and soften edges in our homes. Sound like the perfect decorating fix?
Once you determine that your houseplant finally needs to be repotted because it is far too rootbound – its roots are emerging from the surface of the soil or the drainage holes, there’s no soil left in the pot, or it’s drying out much too quickly between waterings – here are a few tips to follow:
Water the rootbound specimen first, pot up only one size, and while transplanting, be sure to untangle the outer layer of roots.
Gently tease them away from the root ball – you can do this by rubbing the palm of your hand against the ball of roots. If they are too tightly tangled and you can’t loosen them with your hand, you can rub the tines of a fork along the root ball instead.
Untangling its mass of roots will help them spread into their new potting medium more easily, otherwise they may just remain in a tangled ball and won’t get the benefits of new soil and more room.
Now that you know which houseplants will be happy living rootbound in their plastic, ceramic, or terra cotta “homes” for long stretches of time, which ones will you pick to add to your own home? Let us know in the comments section below!
Are you wondering if any of your other favorite houseplants will be happy to live a rootbound life too? If so, feel free to pose your questions in the comments section as well.
It seems so straightforward: grab the watering can, pour some water into the pot your houseplant is growing in, and get on with your day.
But proper watering is one of the most complicated elements of caring for houseplants. And the consequences can be dire if you get it wrong.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
Watering at the wrong time, with too much or too little water can lead to fungal and bacterial diseases that can kill your plants, and underwatering can starve your plant to death.
Advice on hydrating your houseplants can often be vague.
In this guide, we’ll help you understand how, when, and what type of liquid to use to keep your houseplants healthy.
Here’s what we’ll discuss:
I find that in general most beginners to the houseplant world tend to overwater their plants. That was certainly the case for me, and it took me years to break the overwatering habit.
As we go into this, try to consider your current watering habits.
Do you irrigate on a specific schedule? Do you regularly splash liquid on the leaves of your plant? Do you check the soil for moisture regularly?
We all make mistakes, that’s part of life. Let’s discuss how to do it right.
How Often?
If you’re someone who waters on a schedule, stop immediately. Anytime someone recommends that you irrigate a plant according to the calendar, they’re steering you in the wrong direction.
There are so many elements that impact how quickly the soil dries out. It can vary from home to home and even from room to room.
A plant situated in your kitchen might need watering every two weeks, while the exact same specimen set in your living room may need irrigation once a week.
Of course, watering needs vary from species to species. A cactus needs far less than a pilea, for example.
The amount of light the plant receives, if there is any sort of air circulation around the plant from a heat or AC vent, the relative humidity in the air, how compacted the soil is, how much drainage the container has, and what kind of soil you use, are some of the factors that can impact how quickly the soil dries out.
How often you irrigate will depend entirely on your specific plant, and it might change from season to season.
If you’re feeling lost, don’t worry. It’s easy to determine when to water by checking the soil.
This can be done with your finger or by using a soil moisture meter. Once you get to know your plant, you might even be able to tell just by the weight of the pot when you lift it up.
You can also tell if the plant starts to wilt and the soil feels dry. Plants can wilt for other reasons, so don’t immediately assume it’s a drought situation.
The best time of day to water is in the morning rather than the evening because it gives the leaves time to dry and gives you time to empty the drainage saucer or cachepot.
How Much?
As with determining how often to hydrate your plants, working out how much to apply is incredibly subjective.
Again, if someone tells you to add a certain amount, like a cup of water each time, they are steering you wrong.
The amount of water you’ll need to provide depends on the needs of the species you are growing, your particular environment, and the water-retentive qualities of the potting medium.
In the same way as determining when to irrigate, you will need to rely on the soil moisture level to tell you how much to add.
This is where a soil moisture meter comes in handy. It will tell you exactly how damp the potting soil is and then you can compare that to the recommended moisture level for the species you’re growing.
If you don’t have a moisture meter, you can stick your finger in the soil.
“Moist” would be a texture similar to a well wrung-out sponge. Dry would feel like a dry sponge. Wet would feel like a sponge that hasn’t been wrung out yet.
You can also ball the soil up in your hand. If it falls apart, it’s dry. If it stays together but no water squeezes out, it’s moist. If moisture squeezes out, it’s wet.
What Type?
For the majority of plants, good old municipal tap water will do just fine.
If you’re worried, go ahead and leave the liquid in a container without a lid for 24 hours to let some of the chemicals evaporate.
If you have soft water, don’t use it on your plants. Soft water has salts that can rapidly build up in the soil and kill your specimen.
Some species are extremely sensitive to water quality, so for these plants, use rain, filtered, or distilled water.
The water should always be near room temperature. Cold or hot liquid can harm your plant.
How to Water
Now for the easy part, right?
Take your watering can and fill it up. Pour the water out slowly onto the surface of the potting medium.
When you water, apply the moisture to the soil, not like rain on the foliage. Wetting the foliage can often lead to problems with fungal diseases.
Add enough water so that it starts to run out of the drainage holes at the bottom of the pot.
What’s that you say? Your pot doesn’t have drainage holes? You’re playing with fire, my friend.
Unless you’re growing a species that doesn’t mind wet feet – and very few do – a pot without drainage is going to result in standing water around the roots and will inevitably lead to root rot.
You want to make sure the soil is saturated all the way through. If you just add a little bit on the surface, it won’t reach the roots and will encourage shallow root growth, which isn’t ideal for most plants.
Wait 30 minutes after you irrigate, and then empty the outer pot or catchment saucer.
You can also use a process known as bottom watering.
Plants usually aren’t shy about telling you the moisture situation is wrong.
Too much typically results in yellowing leaves, brown patches on the foliage, wilting, and dropping leaves.
Under the soil, the roots turn dark or black and mushy. If you take the plant out of the container, you might get a whiff of something unpleasant.
That’s the build-up of bacteria or fungi and it smells a lot like a vase that has been holding cut flowers for a week.
Too little water results in wilting and dry foliage. If you touch the soil, it will feel extremely dry. Sometimes, this can happen if the medium has become hydrophobic as a result of allowing the soil to dry out too much and too often.
Hydrophobic soil has a waxy layer on top, so when you water, the moisture runs off and down the sides of the container rather than soaking into the medium. Either replace this medium or use the bottom watering method instead.
If your container doesn’t have drainage holes, you need to repot as quickly as possible.
Without adequate drainage, there’s nowhere for the water to escape and even if you don’t add too much, it can still stagnate in the bottom of the pot. This leads to a buildup of bacteria and fungi.
Use a container with drainage and set it inside a decorative pot instead.
In addition, please don’t put rocks or other material at the base of the pot to improve drainage. If I could get rid of one gardening myth, I think this would be it.
Adding this drainage material won’t work and it actually increases the risk of root rot. That’s because there’s a process called capillary action that causes water to pool when it encounters a different texture.
So, the water will collect at the transition between the soil and the rocks or drainage material, sitting closer to the roots, before it eventually drains down into the rocks.
Healthy Plants Start With Water
Mastering the art of watering well is probably the most crucial part of becoming an expert at caring for houseplants.
Finding the right amount, the right timing, and the right type of water for your houseplants will make all the difference in the world in their health.
What kind of houseplants are you growing? Have you run into any trouble figuring out how to water them? Let us know in the comments section below.
African violets (Streptocarpus subg. Streptocarpella sect. Saintpaulia) are one of the few species that bloom indoors with traditional-looking flowers rather than funky inflorescences or itty-bitty blossoms.
The flowers are often violet, but blue, red, white, fuchsia, pink, salmon, and multicolored types are available as well.
They grow perfectly fine in low light, but if you want them to bloom, they need bright, indirect light for a few months out of the year. Otherwise, you’ll have some pretty foliage but not much else.
Since they stay so small, African violets work really well on a desk or shelf under a grow lamp placed about eight inches away.
Amaryllis (Hippeastrum spp.) are some of the most instantly recognizable indoor flowering plants and they brighten up our homes during the holidays with their red, purple, pink, salmon, white, green, or cream blooms.
Anthurium plants are easygoing and will grow in low light, but in these conditions the inflorescences might be lacking in color, or the plant may not bloom at all.
I have one in a woefully dark spot, and it does bloom, but it only produces a few flowers, and they’re muted in color. Instead of red, they’re mostly green with a faint red hue.

I don’t complain because I’m out of spots with perfect light, so it either does its best with what I can give it, or I’ll have to send it to the big garden in the sky.
But if you want yours to put on a big show, give it bright, indirect light, or supplement with grow lights, at least for a few months out of the year. There are lots of color choices out there.
If you want something clean and contemporary, this mini white option from Hirt’s Gardens, available at Walmart, would be perfect. It comes in a three-inch pot.
Honestly, I don’t even care if my begonias (Begonia spp.) blossom. Some of them have such exciting leaves that the flowers are merely supporting players.
I keep my polka dot begonia in pretty dismal light. I just don’t have enough bright spots, and it’s more tolerant of low light than many of my other houseplants.
Polka Dot Begonia.
When you want to encourage blooms, move the plant into morning sun for a few months, and you’ll be treated to a flowering performance.
There are even a few species and hybrids that will bloom in low light.
They’re such accommodating plants! Not all begonia species bloom, by the way, so check the one you’re considering to be sure it’s a flowering type.
For example, the Dragon Wing® hybrid will bloom in pretty much any spot you can find in your home.
The flowers on bromeliads are insignificant, but the spikes that hold them which are leaf-like structures called bracts, are pretty impressive. Most of them won’t bloom indoors, and especially not when they’re growing in low light.
So what is this plant doing on this list? The colorful bracts give you flower vibes even in dark exposure.
The bracts come in red, orange, yellow, green, cream, white, burgundy, or purple. Pretty much all colors except blue. They add color and interest that won’t leave you missing the blossoms.
If you do want to bring on the blooms, it’s possible, regardless of the light you have them in. The secret is to place the plant in a large, clear plastic bag and put an apple in there with it. Seal it shut and leave it like that for three days.
After three days, toss out that apple (or eat it) and take off the plastic. Between six weeks and three months later, depending on the species, the plant will bloom.
Just know that after the flower spike – which can last for months – fades, the plant will die. Don’t worry, you can propagate it by the pups it sends out.
The African violet, Streptocarpus subg. Streptocarpella sect. Saintpaulia, is a compact flower with a whorl of fuzzy foliage that is round or heart shaped, green on top, and often purplish on the underside.
Blossoms in shades of blue, orange, pink, purple, red, or yellow, sometimes bicolored or fringed, perch atop the leaves and are the star attraction.
Aloe vera, aka A. barbadensis, is an evergreen tropical succulent with a very short stem. It stores water in fleshy, pointed, serrated foliage.
Young leaves are green and flecked with white. Indoor plants are unlikely to flower, but those outdoors produce a stalk approximately three feet tall and greenish-yellow blossoms.
Aloe leaves have gel-like centers that contain anti-inflammatory properties. This gel has been long used in herbal medicine to treat burns and stings. Please note that the leaves also contain a layer of latex that may cause an allergic reaction in some people.
When grown indoors, expect mature heights of one to three feet with a spread of two to three feet. Plants prefer loose, sandy soil and have low water needs.
Set in a bright spot, the ideal temperature for cultivation is 55 to 85°F. Aloe does not require humidity, so an average indoor humidity between 30 and 50 percent is suitable.
You can find a 10- to 14-inch tall aloe vera plant in a grower’s pot available from Terrain.
Anthurium, Anthurium spp., is a tropical perennial epiphyte that clings to other flora for support in its native setting.
Some species produce leaf variations called “spathes” that are brightly colored and punctuated by a central “spadix” or fleshy stalk with many tiny blossoms.
Spathe colors may be variegated and include shades of gold, green, purple, red, yellow, and white.
Note that this species is toxic to humans and animals so be cautious about placement if you have curious kids and pets.
Expect a mature height of 12 to 24 inches with a spread of five to 12 inches. Anthuriums prefer a loose, airy potting medium like you would use for a cactus or an orchid. Water needs are moderate.
Provide a setting with bright light and a temperature range of 78 to 90°F during the day and 70 to 75°F at night. A humid environment of 50 percent or higher is best.
Ever-blooming Anthurium ‘Sweet Dream Pink,’ grows to a height of 14 to 18 inches and a width of five inches and is available from FastGrowingTrees.com.
Tropical areca palm,Dypsis lutescens, aka bamboo palm, makes a bold statement in home decor with its multiple stems and narrow, feathery, green foliage fronds.
Expect mature dimensions of five to eight feet tall and three feet wide. Areca palms prefer organically rich soil and have moderate water needs.
The Christmas cactus, aka holiday cactus, Schlumbergera spp., is a flowering tropical succulent.
In its native rainforest home, it grows without soil as an epiphyte, relying on tree bark and other natural elements for support.
The foliage is unique for its segmented cladodes. Multi-petaled, tubular flowers appear at the arching terminal ends in shades of orange, pink, purple, red, salmon, white, and yellow.
Mature dimensions are one foot tall and two feet wide. Christmas cacti prefer organically rich soil and have low to moderate moisture needs.
Ideal bright-light growing environments have daytime temperatures around 70°F and nights in the 60 to 65°F range. High indoor humidity of over 50 percent is best for these plants.
The coffee plant, Coffea arabica, features glossy, dark green foliage and produces red fruits that cluster along its woody stems, each containing one to two coffee seeds or “beans.”
Indoor cultivation is less likely to result in flowering and fruiting than plants growing outdoors.
Mature dimensions may be six feet tall and three feet wide. Indoor plants are usually smaller and easy to prune. Coffee plants prefer loamy, organically-rich soil and have moderate water needs.
They prefer abundant bright light, cool temperatures in the 64 to 72°F range and high humidity over 50 percent.
Donkey’s tails can grow to four feet long with a one-and-half-foot spread. They prefer well-draining cactus and succulent potting medium and have low to moderate water needs.
Keeping pots outdoors in a sunny spot during the warm summer months and in a location between 50 and 69°F in the winter may promote blooming.
To grow clementines, provide bright light and maintain a temperature between 65 and 70°F during the day and 55 to 60°F at night. Keep the humidity above 50 percent.
Another dwarf citrus tree you may like is the Meyer lemon, Citrus x limon ‘Meyer,’ with its glossy green leaves and scented white flowers.
Believed by many in culinary circles to be one of the most flavorful lemon varieties, it is actually a hybrid cross between a citron and a mandarin or pomelo.
Mature heights are six to 10 feet tall with a spread of four to five feet, but indoor plants tend to be smaller and are easy to prune. Cultivate in sandy loam. Moisture needs are low.
Elephant’s ears, Alocasia spp., have bright green leaves accented by prominent white veins.
They are long, pointed, and resemble the ears of the majestic Asian pachyderms of their native lands. Note that these plants are toxic to people and pets.
Species vary, but generally, indoor plants grow between one and six feet tall and one to four feet wide. Elephant ears grow best in a soilless potting medium with moderate moisture.
They require temperatures of 60°F or higher and humidity of at least 50 percent.
Alocasia ‘Black Velvet’ is an exemplary elephant ears cultivar that features velvety leaves in a green-black hue. Mature dimensions are one to two feet tall and wide.
Flaming Katy kalanchoe, Kalanchoe blossfeldiana, aka Christmas kalanchoe, is a succulent species with fleshy, waxy, scalloped leaves and tiny, multi-petaled flowers in vivid shades of orange, pink, purple, red, yellow, and white.
Please note this plant is toxic to people and pets.
Mature dimensions are six to 18 inches tall and wide. Cultivate it in cactus and succulent potting medium with low moisture.
The ideal temperature range is 60 to 75°F, with average humidity, in a bright, sunny location. Flaming Katy may be prone to leaf spot diseases if it’s grown in overly humid conditions.
Haworthia, Haworthia spp., is a fleshy, stemless succulent with pointed, speckled foliage resembling an aloe.
While blooming is not guaranteed when it’s cultivated indoors, haworthia may produce a raceme or flower stalk adorned with tiny, star-like white flowers.
The mature height ranges from three to 20 inches, depending on the species. Widths measure one and a half to 12 inches.
Expect mature dimensions of one to three feet tall and one to two feet wide. Cultivate in water or cactus and succulent potting mix. Plants have moderate water needs.
Lucky bamboo likes a bright placement and can withstand temperatures ranging from 50°F to the high 90s. The average home temperature and humidity are suitable.
The moth orchid, Phalaenopsis spp., is a tropical epiphyte that clings to bark or rocks in the rainforest. It’s one of the easier orchids to grow.
Wax-like brown, orange, pink, yellow, white, or bicolored flowers cluster along gracefully arching racemes protruding from leathery green basal foliage.
Mature dimensions are up to three feet tall and a foot wide. These plants prefer a loose bark orchid potting medium and moderate water.
A bright spot with an indoor temperature of approximately 80°F and nights dropping to about 65°F is ideal. The humidity should be in the 40 to 70 percent range.
Tropical rex begonia, Begonia x rex-cultorum, is prized for its artistically variegated foliage with bumps, ridges, ruffles, a silvery shimmer, and colors ranging from pink and red to maroon and purple, as well as lavender and lime green.
Expect mature dimensions of six to 18 inches tall and wide. Rex begonias prefer a loose, peat-based potting medium and have moderate water requirements.
The ideal temperature is 70°F during the day and 60°F at night with 50 percent or more humidity. Provide bright, indirect light. Note that this species is toxic to pets and people.
Shamrocks, Oxalis spp., have green, purple, or variegated heart-like foliage and pink, red, white, or yellow flowers.
Botanically they are not true shamrocks (Trifolium spp.) but bear a likeness to the three-lobed leaves.
Mature heights range from six to 18 inches tall with a spread of 12 to 24 inches. Shamrocks do best in organically rich, moisture-retentive soil and have a moderate need for water.
Sunny spots with daytime temperatures of 70 to 75°F and 50 to 60°F at night are best. Heat stress and premature dormancy may occur at temperatures above 80°F. The ideal humidity is above 50 percent.
Succulent sweetheart hoya, Hoya kerrii, is an epiphyte that clings to other plants in its native tropical habitat.
Noteworthy for its thick green heart-shaped leaves, this vining species will likely produce wax-like, cream-colored flowers indoors.
Mature dimensions may reach 10 feet long and one to two feet wide. An airy orchid potting medium or a very coarse, loose cactus and succulent soil, and low to moderate water suit this species.
The ideal growing environment has temperatures in the range of 65 to 80°F and never lower than 60°F. The humidity should be in the 25 to 49 percent range.
Venus flytraps prefer bright light and temperatures ranging from 70° to 95°F during the growing season and tolerate a dip as low as 40°F during winter dormancy.
The weeping fig, Ficus benjamina, aka ficus tree, has multiple intertwining trunks and glossy green or variegated foliage. The branches gradually arch with maturity for a cascading presentation.
It may reach up to 14 feet tall with a spread of four feet; however, pruning is an option to keep it more compact. Cultivate in standard potting soil and provide moderate water.

The first time I ever propagated a stem cutting, it was by accident.
I was throwing a party, and I didn’t have time to run to the market to buy flowers for the table centerpiece. So I cut a few stems off my overgrown Swiss cheese plant and stuck them in a vase filled with water.
The leaves stayed lush and healthy, so I left them in the vase for weeks.
I even left them when I went on a week-long vacation. I came back and checked the stems, and what do you know? They had developed a mass of roots.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
I put the surprise plants in some soil, and years later, they still grow happily in my home. In fact, I’ve propagated new specimens for dozens of people in the same way.
I handed them out, along with some of my sourdough starter, during the early days of the COVID-19 pandemic to friends and neighbors who had caught the houseplant and bread making bugs.
All that is a long way of saying that, at least with some species, propagation via stem and leaf cuttings is reliable, simple, and easy-as-pie. Much easier than mastering a sourdough boule.
While we can’t help you perfect your bread baking in this guide, we can help you master the art of propagating houseplants with stem and leaf cuttings.
To help make that happen, we’re going to talk about the following:
The process for either propagation method is fairly similar. It’s mostly a difference in what parts of the plant you snip away from the parent.
Let’s start by looking at some of the species that can be propagated this way.
Species to Propagate via Cuttings
All plants have something called a meristem. It’s the part of the plant that contains cells that are capable of dividing and developing into other types of tissue.
That means the meristematic cells can become roots, leaves, stems, petioles, or any other part of the plant.
Meristems are divided into different types depending on where they occur in the plant.
Apical meristems are present in the roots and the tips of shoots.
Intercalary meristems are in the internodes of the stems (the parts between the nodes) and the bases of the leaves.
Lateral meristems are contained in the cambium layer.
You can make cuttings for propagation based on the types of meristems present in the plant. Basically, you remove the meristematic region, place it in a medium in which it can reproduce, and watch the cell division happen.
Rooting stem cuttings works well with the following plants:
Species that grow adventitious roots, which are roots that develop on the stem above the soil, are all good candidates.
For leaf cuttings, these can be used for:
Before you can take your cuttings, you need to be able to determine which material will work best.
Preparation
While it can vary from species to species, most propagation methods work best if you choose healthy, mature tissue.
In the case of stems, you want a cutting about six inches long with at least two nodes. The leaves for leaf cuttings should be large and mature, and without any discoloration or dead areas. Avoid tiny or new leaves.
The best time of year for propagation is typically during spring and summer when plants are actively growing.
Many species go dormant in the late fall and winter, and that means they might not develop roots before rot sets in.
Avoid propagating stunted leaves and stems and any tissue with brown or yellow areas, spots, or other signs of disease, such as the presence of fungal spores.
Whether you reuse pots or choose new ones, wipe them out with isopropyl alcohol or a 10 percent solution of bleach and water (one part bleach to nine parts water).
Young specimens are extra vulnerable to disease and you want to prevent any pathogens from infecting your plants by sterilizing your tools.
You should always use fresh potting medium for this reason, and avoid those that contain garden soil. Seed-starting mixes are a smart option.
Tank’s Pro-Lite Seeding and Potting Mix is one of my favorite options. It’s light and airy thanks to the addition of coconut coir and perlite.
Make sure your tools are clean, too. You can wash them in soapy water and then wipe them with alcohol or watered-down bleach.
Regardless of the method of propagation you choose, make a note of the light preference of the species you are propagating.
Most houseplant cuttings do best in bright, indirect light, but there are exceptions. Some species need direct light for at least part of the day.
There are few, if any, plants that should be propagated in a dark spot.
Stem Cuttings
Stem cuttings can be taken in several ways. For plants that have canes, you can take the cane along with some leaves.
Leaf bud cuttings involve removing a small piece of stem with the petiole, if the plant has them, and a leaf. A standard stem cutting includes a piece of the stem and at least two buds.
Leaf Bud Cuttings
Devil’s ivy (Epipremnum aureum), dracaena, jade plants, rubber trees (Ficus elastica), fleshy peperomia, and philodendron can all be propagated by leaf bud cuttings.

For a bud cutting, take just an inch or two of stem that contains a single bud and a single leaf. Moisten the stem and lightly coat the cut end in rooting hormone.
Place the cutting in the medium so that the bud is buried, but the leaf is above the medium.
Water the medium well so that it feels like a well-wrung-out sponge and tent a piece of plastic over the new plant.
The plastic should never touch the leaves, so you might need to prop it up with a stick. I save my take-out chopsticks for just such an occasion.
Cane Cuttings
Chinese evergreen, dracaena, dumb cane, and any other species with thick stems or canes can be grown via cane cuttings.

To take the cuttings, remove a section of stem with a sharp knife.
Section the cane into two-inch segments, taking care to include a node, bud, or horizontal ring in each segment. Roots will emerge from these areas.
Note which side is up on each segment so you don’t accidentally plant the segment upside-down.
Dip the cut end in root hormone and set each segment in the medium, buried by about a third. You can also place the canes horizontally, pressed into the surface of the soil.
Water the medium and cover the cane with a tented plastic bag.
Herbaceous or Softwood Stem Cuttings
Many plants can be propagated via herbaceous or softwood stem cuttings.
Photo by Kristine Lofgren.
To take a stem cutting, remove a piece of stem between three to six inches long that includes at least three sets of leaves. The bottom cut should be just below a node.
Remove half to two-thirds of the lower leaves. If the specimen has large leaves, like a fiddle-leaf fig, for example, cut the remaining leaves in half.
Dip the cut end in powdered rooting hormone. Poke a hole in the potting medium with a chopstick or pencil and gently lower the stem into the hole.
A quarter of the length of the cutting should be submerged in the medium.
Photo by Kristine Lofgren.
Moisten the potting medium. You can tent plastic over the container, but it isn’t required with these cuttings unless the particular species you are propagating needs high humidity.
Leaf Cuttings
There are three types of leaf cuttings suitable for propagation. The first is a leaf with its petiole, which is the stem-like growth that holds the leaf to the stem.
The second is a leaf without the petiole, sometimes called a leaf blade cutting.
This propagation method is commonly used with cacti and succulents, as well as African violets and Cape primroses (Streptocarpus spp.). Plants with thick, fleshy leaves work best for this method.
The third is vein cuttings. Begonias are the classic choice for propagation via this method.
Some species, such as snake plants, have leaves that can be chopped up into several sections for planting. You should take the entire leaf of plants like ZZ plants and African violets.
These types of cuttings generally take longer than stem sections to develop sufficient roots that they can be transplanted.
Don’t be surprised if it takes several months before you see any evidence of roots forming.
Leaf Blade
To propagate with a leaf blade, snap or cut off the leaf from the stem or just above the soil.
In the case of thick, succulent leaves, these should be left out on a piece of cloth or a paper towel for a day to develop a callus on the cut end. This callus helps prevent rotting.
Photo by Kristine Lofgren.
Once the end is callused over and feels firm and dry, moisten it and dip the cut end in rooting hormone. Insert the leaf into the growing medium so the leaf sits about a third of its length deep.
Keep the medium moist until roots develop. Even cacti should be kept slightly moist until they develop roots.
If the species you’re working with thrives in high humidity, cover with a cloche or plastic bag propped up with a stick.
Leaf Petiole
This method is similar to leaf blade propagation, but you simply take the cutting to include some or all of the petiole.
Photo by Kristine Lofgren.
When planting the leaf in the medium, only the very bottom of the leaf should be in contact with the medium.
After planting, moisten the medium and cover the pot in plastic propped up with a stick or a cloche, and place the container in an area with bright, indirect light.
Most species will develop several plantlets from each cutting. You can gently separate these and plant them individually or leave them together.
Leaf Vein
For plants like begonias, cut off a leaf that has lots of prominent veins.
Lightly dust the bottom with rooting hormone and lay it on top of the potting medium. Use horticultural wire or paper clips to anchor the leaf into the mix.
The whole section must remain in contact with the medium or roots won’t be able to form.
Moisten the potting mix and cover the pot with plastic. Eventually, plantlets will emerge from the leaf. Separate these and place them in their own containers.
When to Transplant
Regardless of the type, most popular houseplants do best in bright, indirect light and in soil that is moist, like a well-wrung-out sponge.
You can check for roots after a few weeks by working your fingers under the plant and gently lifting it up. If you don’t see any roots or the roots you do see are just beginning to emerge, put it back in place and check again in a few more weeks.
As long as there is no sign of rot, you can keep waiting for roots to develop. Some species take months, so don’t lose heart.
Once you see root development, remove the plastic bag if you used one. Give it another week or two in the same conditions, and then move it into a permanent pot or location.
How to transplant depends entirely on the species you’re working with. In general, you don’t want to move a young specimen to a container that is too large.
One size up from the existing container should be sufficient. When you transplant, try to dig up some of the soil surrounding the new roots, if you can, to reduce shock.
Make More Marvelous Plants
It’s expensive to buy new houseplants. If you have access to a parent plant, whether your own or one belonging to a generous friend, you don’t need to buy them. You can propagate your own.
