Mini Calla Lily: A Guide to Care and Propagation

Introduction

The mini calla lily, also known as Zantedeschia aethiopica, is a stunning and versatile plant often grown for its elegant, funnel-shaped flowers. These compact varieties, typically reaching heights of 12-18 inches, are perfect for adding a touch of sophistication to indoor or outdoor spaces. Their delicate blooms come in a range of colors, including white, yellow, pink, and purple, making them a versatile choice for any décor or landscape.

Care

Lighting

Mini calla lilies prefer bright, indirect light but can also tolerate partial shade. When grown indoors, place them near a window that receives several hours of sunlight per day. Outdoors, they can be planted in a location with morning sun and afternoon shade.

Watering

Water mini calla lilies regularly, allowing the soil to dry out slightly between waterings. Overwatering can lead to root rot, so it’s important to avoid keeping the soil constantly wet. During the growing season, water deeply and less frequently, and reduce watering in the winter months when the plant is dormant.

Soil

Mini calla lilies thrive in well-draining, organic-rich soil. A potting mix designed for African violets or a mixture of equal parts peat moss, perlite, and compost is ideal. Ensure the soil pH is between 5.5 and 6.5, slightly acidic to neutral.

Fertilizing

Fertilize mini calla lilies monthly during the growing season with a balanced liquid fertilizer. Use a fertilizer with a ratio of 10-10-10 or similar and dilute it to half strength. Avoid over-fertilizing, as this can lead to foliage burn.

Humidity

Mini calla lilies appreciate high humidity, especially during the winter months when indoor air can be dry. Misting the plant regularly or placing it on a tray filled with pebbles and water can help increase humidity levels around it.

Propagation

Dividing

The most common method of propagating mini calla lilies is by dividing established plants. In spring or fall, gently dig up the plant and divide the rhizomes into sections, each with several healthy stems and roots. Replant the divisions in well-draining soil and water deeply. Keep the soil moist and provide bright, indirect light until new growth emerges.

Seeds

Mini calla lilies can also be propagated from seeds, although this method takes longer and is less reliable. Sow seeds in spring or summer in a seed starting mix and keep them moist and warm. Provide bright, indirect light and transplant the seedlings outdoors once they have developed several true leaves.

Troubleshooting

Yellowing Leaves

Yellowing leaves can indicate several issues, including overwatering, under-fertilizing, or a lack of light. Adjust watering and fertilizing schedules accordingly and ensure the plant is receiving adequate sunlight.

Brown Tips on Leaves

Brown tips on leaves can be caused by low humidity or excessive salt accumulation. Increase humidity by misting the plant regularly or placing it on a tray filled with pebbles and water. Flush the soil thoroughly to remove excess salts.

Pest and Diseases

Mini calla lilies are generally pest and disease-resistant, but they can occasionally be affected by aphids, spider mites, or thrips. Treat infestations promptly with an appropriate insecticide or pesticide.
