It is easy to split calla lilies. Do not lift calla lilies rootstock until the foliage turns brown and pulls away from the roots easily. Slide a shovel under the roots and pry upward to lift the clump. Clean all the leaves that remain and the soil as well. Cut or break apart the rootstock, remember that it is necessary to contain at least one eye in each part. Dry the rootstock for one day aiming at allowing the callus to form over the cut before you replant.

If live in an area cooler than USDA plant hardiness zones 8 through 10, you should store the rootstocks over winter and grow them in spring. Let them dry in a well-ventilated place for two to three days. Before dust the bulbs with bulb dust to prevent them from destruction, use your hand or dry paper to clean all the remained dirt. Use a paper bag or newspaper to wrap them. Then, place them in a cool, dry environment which stays around 50 F (about 10 C).

In the end of winter or spring, cut the sections of the plant apart by split a spade between them the sign of new growth appearing. Remove your chosen sections and replant them immediately. Add soil around the plants and use your hangs to firm it up. Starter may find this way for splitting calla lilies easier since there no need to define the eyes.
