Cara Davies remembers the day the city inspector came to take a final look at her garden before signing off on the building permit: “He came around the corner and he was quite surprised—and he said, ‘Oh my gosh, it’s a little bit of paradise.’” The garden shed gets the credit.
No one would have described the .3-acre property in downtown St. Helena as paradise in 1999 when Davies and her husband, Tom, moved into the Napa Valley house. “There wasn’t much here, just a little lawn with a deck, so we completely redid the backyard,” she said. Landscape architect Josh Chandler designed the garden as well as the galvanized shed, which owes its charm both to its unusual proportions and facade of corrugated steel panels salvaged from old chicken coops.

Above: Chandler designed the 10-by-10-foot square shed to sit alongside Davies’ edible garden, next to the swimming pool. The shed’s unusual height–it’s 20 feet tall–and peaked roof make it the center of attention. Above: The shed’s siding is vintage galvanized steel panels, salvaged from a former farm with chicken sheds that dated to the 1920s. Growing next to the shed is salvia whose deep purple color is intensified by the gray backdrop. Above: The shed sits on a solid concrete pad etched with lines to evoke the look of pavers. A path of permeable pea gravel leads to the shed. (For more ideas about how to use pea gravel in the garden, see Hardscaping 101: Pea Gravel.)
I don’t know any gardeners who casually grow dahlias. Their fireworks riot of color has an intoxicating effect. You may start with one dahlia, but before you know it you have torn out the roses, planted five hundred tubers and (in at least one documented case), transformed an old tennis court into a fenced garden to make room for more flowers.
But dahlia devotees pay a price. In cold climates (read: the ground freezes), dahlia tubers need to come out of the garden if they are to survive the winter. Dig them up and store them in the basement, garage, or a protected shed—and dahlias will reward you next summer with more enormous puffball blooms. It’s worth the effort.
Here are step-by-step instructions for how to store dahlia tubers in winter:

1. Wait for the first frost.
Above: Dahlias will bloom well into autumn if you deadhead them to coax more flowers. But frost will put a stop to that.
Flowers will wilt, leaves will blacken, and dahlia stems will die back after the first frost; you’ll know it’s time to store tubers in a safe spot for the winter.
2. Dig up dahlias.
Above: Be careful when you dig up dahlias because, as you can see, a single plant may have a clump of connected tubers and a far-reaching root system.
To dig up, first cut back stalks to a height of 2 to 3 inches. Then start about a foot away from the plant, loosening soil all around the roots and digging deep enough (18 to 24 inches) to get your shovel underneath the dahlia to tease it out of the ground.
Dig up one clump of tubers at a time and be gentle; the tubers are fragile and break apart easily.
3. Rinse off dirt.
Above: Use a gentle spray from a garden hose to wash off soil so you can see the tubers and root system of individual clumps of dahlias.
