I plan to plant some ginger this year (if I ever get the time). I am in zone 5 so I know it won't survive the winter. I have a cold cellar and thought I might plant some in a pot, let it go dormant in the fall and store the pot in the cellar until next spring.
Is there any reason this would not work? Do I need to grow it indoors as a houseplant instead? This can be done, I just don't have a lot of room in a sunny location for houseplants.
I want to grow some of the decorative flowering gingers so I thought it would need a long life span to reach that stage.
I also want to grow some for eating from roots at the grocery store. I am going to look for sprouting older roots at my next visit to the store.
