Cultivation Conditions

Light Requirements

Zantedeschia thrive in bright, indirect light, similar to the dappled shade they receive in their natural habitat. Avoid exposing them to direct sunlight, as it can scorch their delicate leaves.

Temperature and Hardiness

Most Zantedeschia species are tropical or subtropical, preferring warm temperatures between 60-75°F (15-24°C). They are not cold-hardy and should be protected from frost and freezing temperatures. In colder regions, they can be grown as annuals or overwintered indoors.

Soil and Drainage

Zantedeschia prefer well-drained, organic-rich soil with a pH between 6.0 and 6.5. The soil should retain moisture but not become waterlogged.

Planting and Propagation

Planting Corms

Zantedeschia are typically grown from corms, which are underground storage organs. Plant the corms pointed end up, about 2-3 inches deep and 4-6 inches apart. Water well after planting.

Division

Mature Zantedeschia plants can be propagated by division. Carefully dig up the plant in spring or fall, and separate the corms into smaller clumps. Replant the divisions immediately.

Care and Maintenance

Watering

Water Zantedeschia regularly, especially during the growing season. Allow the soil to dry out slightly between waterings. Overwatering can lead to root rot.

Fertilizing

Feed Zantedeschia with a balanced liquid fertilizer every 2-3 weeks during the growing season. Stop fertilizing in the fall.

Pruning

Remove spent flowers and yellowing leaves to promote new growth and prevent disease.

Pest and Disease Control

Zantedeschia are generally pest and disease resistant, but they can be susceptible to aphids, spider mites, and snails. Treat infestations promptly with appropriate pesticides or organic remedies.
