Introduction

Calla lilies, with their elegant trumpet-shaped flowers, are a beloved addition to any garden. Planting their bulbs is an easy and rewarding task that yields stunning blooms. This comprehensive guide will provide you with all the knowledge and tips you need to ensure successful calla lily bulb planting.

Choosing Healthy Bulbs

Selecting healthy bulbs is crucial for successful growth. Look for bulbs that are:

• Firm and plump, without any soft or mushy spots
• Free of blemishes, scars, or bruising
• About the size of a golf ball or slightly larger

Preparing the Soil

Calla lilies prefer well-drained, fertile soil with a pH between 6.0 and 6.5. If your soil is heavy or clay-like, amend it with compost or peat moss.

Dig the planting holes twice the width of the bulbs and as deep as the bulbs are tall.

Planting the Bulbs

Position the bulbs pointy side up, about 6 inches apart. Gently press them into the soil, leaving the tops exposed.

Cover the bulbs with soil and gently firm it around them. Ensure that the tops of the bulbs are just above soil level.

Watering

Water the bulbs thoroughly after planting. Keep the soil moist but not waterlogged.

Fertilization

Fertilize calla lilies every 4-6 weeks with a balanced liquid fertilizer.

Sunlight and Temperature

Calla lilies thrive in partial shade to full sun. They prefer temperatures between 55 and 75 degrees Fahrenheit.

Mulching

Mulching around calla lilies helps retain moisture, suppress weeds, and regulate soil temperature. Use organic mulch such as compost or shredded bark.

Common Pests and Diseases

Calla lilies are relatively pest- and disease-resistant, but they can be susceptible to:

Aphids

Treat aphids with a mild insecticidal soap spray.

Slugs and Snails

Handpick slugs and snails or use slug bait.

Root Rot

Avoid overwatering or planting in poorly drained soil, which can lead to root rot. If root rot occurs, remove the affected plants and improve soil drainage.

Tips for Optimal Bloom

• Choose cultivars that suit your climate and bloom time.
• Provide adequate sunlight and water.
• Fertilize regularly.
• Deadhead spent flowers to encourage new blooms.
• Divide overgrown plants every 3-4 years.
