overwintering canna tubers - best method?
How should I store my canna tubers for the winter? I got some this spring from my sister in St. Louis, and the plants were magnificent this year, and multiplied like crazy. I really want to save them. Should I dig them up and layer them in a box with loose mulch or peat moss? How damp/dry should they be stored? Would a cool basement be suffucient for them? Thank you for your help!
