Are Calla Lilies Suitable For Winter Storage?

Calla lilies are a beautiful and versatile flower that can be grown indoors or in pots. They are known for their stunning flowers, which are traditionally used in wedding bouquets and Easter arrangements. To keep them healthy during winter, it is recommended to dig up the rhizomes of potted calla lily plants and store them in a dry place with a 50F temperature. In warm climates, mulching the spot where the calla lilies grow is another effective way to keep them healthy.

To overwinter calla lilies, dig up the entire plant, including the bulb, in late fall before the first frost. Gently shake off any debris. The humidity and warmth indoors during winter provide ideal conditions for seed propagation, and dividing calla lily bulbs is another option for increasing growth.

Calla lilies are tender perennials, and their rhizomes must be dug up in fall and stored indoors over the winter months. After a killing frost, cut off the foliage 1 to 2 inches above the soil surface. If you live in USDA plant hardiness zone 8 or higher, your calla lilies can survive the winter outdoors in the ground without needing to be dug up. However, calla lilies are not hardy and cannot overwinter outdoors in our country.

Hardy varieties of Calla lily tend to be white and will survive overwintering outdoors in many climates. More tender varieties are usually colored and may be frost-tender. Most calla lilies are frost-tender, and their rhizomes or fleshy roots can be stored over winter and then replanted the following spring.
