Calla Lily Plant Facts

August 18, 2023

Calla lilies (Zantedeschia spp.) are renowned for their graceful elegance, making them a popular choice among gardeners and florists alike. With their distinctive trumpet-like shape and captivating colors, Calla lilies add a touch of sophistication to gardens, landscapes, and floral arrangements. These perennial plants, native to southern Africa, are known for their striking presence and are a favorite for weddings, special occasions, and artistic floral displays.

Planting Zones: Calla lilies thrive in planting zones 8 to 10. They are generally not suited for colder climates but can be grown as tender bulbs in cooler areas or brought indoors during the winter.

Growing Guide:

1. Location: Choose a location with well-draining soil that receives partial to full sunlight. Calla lilies prefer slightly acidic to neutral soil pH levels.

2. Planting: Plant Calla lily bulbs in the spring after the last frost date. Space the bulbs about 12 to 18 inches apart and plant them 2 to 4 inches deep, with the pointed end facing upward.

3. Watering: Keep the soil consistently moist but not waterlogged. Water thoroughly when the top inch of soil feels dry. During the growing season, increase watering frequency, especially during hot and dry periods.

4. Fertilization: Feed Calla lilies with a balanced, all-purpose fertilizer every 4-6 weeks during the growing season. Follow the manufacturer’s recommendations for application rates.

5. Mulching: Apply a layer of organic mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

6. Care:

7. Overwintering: In colder climates, dig up the bulbs after the first frost once the foliage has turned yellow. Allow them to dry for a few days, then store them in a cool, dry place for the winter. Replant the bulbs in the spring.

Pruning: Cut back the faded flowers and stems to encourage new growth and prolong the blooming period. After the growing season, cut the foliage back to the ground.

Calla lilies are prized for their long-lasting and stunning blooms. By following these planting and care instructions, you can enjoy these exquisite flowers in your garden or bring their beauty indoors for elegant floral arrangements.
