Can I dig up my Calla lily bulbs now and put them in a bucket in the basement and plant early spring?

Your calla lilies should winter over in the ground in hardiness zone 7, covered with mulch. Your zip code came up with 6 and 7 for the zone, so if you are in 6, you may want to dig them up. They should be overwintered in a frost-free area. Here is how:
