Do calla lily bulbs need to be dug up in the winter?
Hardiness Zone: 7b
By Chelle from Savannah, TN
I also live in central VA--Zone 7 and according to packaging labels the Calla Lilies are not hardy to Zone 7. I did dig mine up the first year (about 10 years ago). What a job!! I decided then that they weren't worth it and I would buy new ones every year. Didn't have to buy new ones because they have come back every year since.
In the fall I cut the old foliage down and just leave it on the bed as an insulation. I have so many now that I am giving them to all our neighbors and relatives. This past winter was one of the coldest in many years. I'll just have to wait & see if they come back. If you live any further north than zone 7 you may need to dig them up or treat them as an annual.
