When we moved last year, I dug up some of my favorite Calla Lilies that I had been growing for years and I repotted them to save for my new garden this year. I let them overwinter in a ceramic pot on my back porch in regular potting soil. I potted them and just let them be. I manually watered them maybe twice and just let the occasional rain water them. I didn’t have to care for them at all. I just left them in the pot in a sunny spot where they would get rain water. I planted the bulbs in my new garden the same day after I separated them.
