What is a Lemon Drop Calla Lily?
The Lemon Drop Calla Lily (Zantedeschia aethiopica ‘Lemon Drop’) is a captivating cultivar of the Calla Lily family, native to South Africa.

Growing Lemon Drop Calla Lilies
Hardiness and Sunlight Requirements
Lemon Drop Calla Lilies thrive in USDA hardiness zones 8-11, but can be grown as annuals in colder climates. They prefer full sun to partial shade, ensuring at least 6 hours of sunlight per day.
Soil and Planting
These lilies thrive in well-drained, fertile soil rich in organic matter. Before planting, amend the soil with compost or manure. Dig a hole twice the width of the bulb and plant it 4-6 inches deep, with the pointed end facing up.
Watering and Fertilizing
- Water regularly, especially during the active growing season (spring and summer).
- Keep the soil moist but avoid overwatering, which can lead to root rot.
- Fertilize monthly with a balanced liquid fertilizer during the growing season.
Care and Maintenance
Division and Repotting
As the plant matures, it may become crowded. Divide the bulbs every 3-4 years to promote healthy growth and flowering. Repot the divided bulbs into fresh soil in larger pots or replant them in the garden.
Pests and Diseases
- Aphids: Treat with insecticidal soap or neem oil.
