Caring for Calla Lily
- Keep them adequately fertilized and watered, misting the plant every so often to keep the ambient humidity high.
- They are susceptible to aphids so, take a look closely and apply insecticide.

Grow calla lily bulbs in well-drained soil, especially in spring, to grow best and to avoid bulb rot. In the ground or containers apply a monthly dose of an organic fertilizer during the growing season. Keep container bulbs well-watered for best growth. Harvest flowers in the cutting garden as they color up and open for indoor arrangements.
Once calla lilies have stopped flowering and the foliage begins to die back in fall, dig up and store the bulbs in cold climates. Even if growing calla lily bulbs in a warm climate, every few years dig up, divide and replant the bulbs to stimulate better growth and more flowering. Bring containers of calla lilies indoors in fall in cold climates to overwinter in a cool, dark basement.
