You probably would have to dig them Jeanne (unless you want to buy new ones next year). They are so easy to grow and are stunning flowers, always get great comments in the garden.
Callas are easy to dig up and store because they keep their foliage until fall. I like that you don't have to guess where the bulbs are. I just dry mine thoroughly, then put them in a paper bag and put them in the basement. Some people do store them in pots or add dry peat moss to the storage.
