When To Divide Calla Lillies

Question

I live in Wisconsin and have Calla Lillies that come up every year for the past 5 years. The plant is on the sunny side of the house, that’s probably why it has been surviving the winters all this time. It’s time to divide them. I started getting odd looking flowers, sometimes twins and triplets on one stem. Should I wait until next spring when the ground warms up or can I divide them in fall after turning brown? I’m afraid to disturb them and do not want to end my Calla Lily legacy 🙂 Thank you, Sue in WI

Since you leave them in the ground, wait till next spring after all danger of frost has passed before dividing them. Here is how:
