The plant requires wet growing conditions and basks in bright and indirect light for at least six hours a day. If living in humid and hot summer weather, calla lilies thrive better when placed in spots with good drainage and sunlight.

Calla lilies have a bloom window of about 3-8 weeks, with flowers persisting for up to 12 weeks in containers or beds. To maintain their health, keep the plant root bound and maintain a well-draining soil, adequate sunlight, and regular watering. Cut calla lilies can last up to two weeks if kept in a vase with fresh water and regularly trimmed and cared for.

The plant usually blooms for about six weeks during the late spring and early summer but may bloom at any time when indoors. Keep container-grown plants potbound to ensure proper growth. Calla lilies are easy to grow outside, as long as you live in USDA hardiness zones 8-10. They grow from a single rhizome, not from a bulb, which is crucial for their health.

Calla lilies make a strikingly beautiful houseplant and are low-maintenance, with a little care they will return year after year.

Root rot in Calla lilies is a common issue due to overwatering or poor drainage, which can cause fungal infections like Phytophthora or Pythium. Symptoms include yellowing leaves, wilting, a mushy or smelly root system, and overall plant health decline.

What to do with indoor calla lily after flowering?

Zantedeschia, a plant known for its annual flowers, requires proper care and maintenance. After flowering, the foliage will begin to yellow and die off. To maintain the plant, prune it back above the soil line and place the potted rhizomes in a dark location with low humidity and temperatures around 10°C (50°F) for a couple of months. Water sparingly to prevent root or pythium rot. Once the foliage re-emerges in spring, weakly fertilize the plant using a ‘Houseplant’ labelled feed and increase the number of waters per week. Relocate the specimen in a bright location with little to no direct sunlight to acclimate to the new surroundings.

Root rot is a common issue with Zantedeschia, causing rapidly yellowing leaves, mouldy soil, stunted growth, and a rotten collapsed base. If the roots show a yellow tinge, the plant is healthy, but brown and mushy roots must be addressed immediately. If the plant develops basal collapse, it may be the end of its life. To manage root rot, remove the plant from the pot, prune away rotten areas, check the base for a softened profile, remove rotten plants, repot healthy specimens in fresh compost, provide a brighter location, and reduce watering slightly to avoid further rot.
