How to Care for Potted Calla Lily Bulbs After Blooming

Calla lilies grow from rhizomes, a bulb-like type of root that stores energy. Calla lilies can't survive cold winters, so in cold locations, you must dig up the rhizome and store it until spring. If you are in a warm location, you may be able to enjoy your calla lily's foliage all winter, although it won't bloom again until the weather becomes warmer.
