Potted calla lilies should be placed in an area that receives plenty of sunlight in the morning and evening shade or in an area with partial shade throughout the day. The lilies should be planted in a coarse growing medium that is well-draining, such as a combination of pine compost and sand, rather than soil. Lime and root rot suppressants may be added to the growing medium as needed to promote healthy growth and prevent disease from affecting the lily.

Calla lilies bloom in spring and prefer temperatures of 75 degrees Fahrenheit or lower directly before blooming. Use a sun shade if the lilies are in a sunny location. If possible, prevent dew and humidity to ensure the root systems are protected from rot. Water the potted lilies when the topmost layer of the growing medium is dry, and fertilize twice monthly during the growing season to produce ample blooms.

Calla lilies are grown from rhizomes that can be used year after year to produce blooms. The rhizomes should flower within 8 weeks, but in some cases the rhizome may take much longer to produce blooms. Store the calla lilies in the container during winter, and water sparsely until the next growing season to preserve and reuse the rhizomes.
