Calla lilies are typically divided in spring or fall, especially in warm climates where the rhizome can remain in the ground year-round. The best time to divide calla lily bulbs is during their dormant period, typically in late winter or early spring. This allows the bulbs to establish new roots before growing. In cooler areas, the best time to split calla lily plants is in the spring or fall, as the plant is not actively growing.
There are two ways to split calla lilies rootstocks: at the end of winter or the beginning of spring when there are no rhizomes, and replant the separated calla lilies 2 to 4 inches deep, allowing 18 inches between each rhizome. Water the area deeply one time after splitting. Lilies produce from bulbs and need to be divided and transplanted in the fall for the best results. Experts recommend late September or early October for moving lilies and dividing them immediately.
The Royal Horticultural Society suggests dividing calla lilies in spring if needed, as small rhizomes that have been overwintered in pots under cover can be cut up into sections with visible buds. In late winter/early spring just before new growth begins, dig the rhizomes (or unpot) and divide by breaking apart the mass.
Growing calla lilies is easy, but it is important to let them go dry, giving them a rest for a few more weeks before starting them again during spring or summer months.

Calla lilies multiply very fast. You need to thin them down every 2 to 3 years otherwise they will not bloom well.

Calla lilies bloom in springtime when the weather is still cold and damp. Once they are done blooming, you can divide them and …
Such a helpful article. Since you did this at the end of summer and got new growth during the fall do you cut it all the way down during the winter or just let the leaves brown and remove the old foliage in the spring? Do you keep your containers inside during the winter ? I read in some places you should put the bulb in a paper bag, is that necessary when growing in containers. Thank you for the reponse.
@easy Peasy gardening I really enjoyed your article & knowledge! Great Job!! 😍 I bought a calla Lilly kit (one tiny bulb) is it possible to expect a healthy robust plant from such a small bulb? I’m planning on purchasing 2 more kits (for a variety of colors) and plant all three in a big pot, I will make sure they have adequate spacing….Love the pink, yellow & purple hues. 🤗 🙏💖 God Bless you immensely in this year.
Ok now I make a tough comment. After you divided them the mother plant threw up a new flower shoot but it didn’t stand up properly. The angle you shot it on was not showing how it wasn’t fortified enough to stand up. Is that permanent or did it take a, season for it to start sending out a straight up flower stem. Because dividing the bulbs during the rest period at the end of the season is perhaps less traumatic on the plants where you could separate the smaller bulbs by washing the roots down of soil and exposing the area to divine. Did that mother plant ever send flowers that stood straight up ever again? Thank you.
We have these same white calla lilies in our yard, but unfortunately a few of the plants have turned yellow and started to limp over (early May of 2020). Could this be because they are receiving too much sunlight? We have had record-breaking warm weather this spring, in California, as well. So, maybe it has been too hot for these plants that get more sun?
Hi. I just ordered some white calla lily bulbs but they are a little dry and they don’t have any sprouts. Now I am super confused which side is up. I don’t want to put them upside down what should I do? I have some asiatic lily bulbs chilling in some damp cocopeat mixed with fungicide. Should I put them there to sprout?
