Calla Lily Plant Care

Calla Lily (Zantedeschia aethiopica) belongs to the Araceae family within the Zantedeschia genus. Calla Lily is native to southern Africa in Lesotho, South Africa, and Eswatini. Calla Lily is also known as Arum lily, Lily of the Nile, Pig lily.

Calla Lily displays a clumping perennial growth habit, reaching up to 2 inches tall with a spread of approximately 1.5 inches. Calla Lily produces showy, trumpet-shaped flowers in various colors.

Leaf size: approximately 12 inches.

Zantedeschia aethiopica requires watering every 5–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Calla Lily thrives in bright indirect light light conditions. The optimal light range is 1000–2000 lux. Avoid placing Calla Lily in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Zantedeschia aethiopica grows best at temperatures between 60°F and 75°F. Calla Lily prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with plenty of organic matter. Good drainage is essential for Calla Lily to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 1-2 years in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Calla Lily can be propagated through division of rhizomes, seeds.

Calla Lily is susceptible to aphids, spider mites, thrips. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Calla Lily grows outdoors in USDA Zone 8a – 10b. Native to southern Africa in Lesotho, South Africa, and Eswatini, Calla Lily is adapted to warm climates. In cooler regions, grow Calla Lily as a houseplant or bring it indoors before the first frost.
