I plan on creating my first raised bed in the spring. I can't wait! I want to plant Lilacs in what will probably be cedar boxes. How much soil would I need, and is this doable in my zone?
Thanks in advance.
My mother grew Lilacs in soil that was almost all gravel in a Zone 5 climate (Spokane, Wa.) with an average of 17 inches of rainfall a year. She never watered them and they grew very well. She finally had a backhoe take them out when she upgraded her garden.
