When And How Calla Lilies Should Be Divided?

Calla lilies are beautiful and elegant plants that can add a touch of beauty to any garden or indoor space. They are best divided in spring or fall, when the plants are dormant and there are no more threats from frost. In warm climates, the best time to divide calla lilies is either late winter or early spring after all danger of frost has passed or in late summer or fall when the plants have finished blooming for the year.

Dividing calla lilies is a simple process that can help propagate and rejuvenate your plants. The Royal Horticultural Society suggests dividing in spring, especially in warm climates where you can leave the rhizome in the ground year-round. In cooler areas, you can wait until after the last frost date in late winter or early spring. In colder climates, divide calla lilies in the fall once foliage has begun to die back.

To split up the rhizomes of your calla lilies, the best way and time to do this is when you first notice the tiny green new shoots begin to form. The best time to divide calla lily bulbs is during their dormant period, typically in late winter or early spring. Divide calla lily rhizomes in late winter before replanting.

There is no set timetable for dividing calla lilies, as they can be divided during the winter months whenever it’s necessary. The clumps are dug up and segmented into smaller pieces.
