Calla Summer Sun: A Comprehensive Guide to Growing and Care

Introduction

Calla summer sun, also known as a Calla lily, is a stunning herbaceous perennial that adds a touch of elegance to any garden. With its vibrant blooms and lush foliage, it’s a popular choice for both novice and experienced gardeners alike. This comprehensive guide will provide you with all the essential information you need to grow and care for your Calla summer sun.

Growing Conditions

Light

Calla summer sun prefers full sun to partial shade. They thrive in areas that receive at least 6 hours of sunlight per day, but can also tolerate partial shade. If planting in partial shade, ensure the soil is well-draining and amended with organic matter to improve fertility.

Soil

These plants prefer well-drained, fertile soil with a pH between 6.0 and 6.5. Amend heavy clay soils by adding sand or compost to improve drainage and aeration.

Watering

Calllas require consistent watering, especially during hot, dry weather. Water the soil deeply and regularly, allowing the top 2-3 inches of soil to dry out before watering again. Avoid overwatering, as this can lead to root rot.

Fertilizing

Fertilize your Calla summer sun monthly during the growing season with a balanced liquid fertilizer. Alternatively, you can apply a slow-release fertilizer according to the manufacturer’s instructions.

Planting

1. Choose a planting site that meets the plant’s light and soil requirements.
2. Dig a hole twice the width of the root ball and just as deep.
3. Place the Calla summer sun in the hole and gently spread out the roots.
4. Fill the hole with soil, tamping it down lightly to remove any air pockets.
5. Water the plant deeply and mulch around the base to retain moisture and suppress weeds.

Care and Maintenance

Mulching

Mulching around your Calla summer sun is essential to retain moisture, suppress weeds, and regulate soil temperature. Use organic materials such as bark, compost, or shredded leaves.

Deadheading

Removing spent blooms (deadheading) encourages the plant to produce more flowers. Deadhead regularly by cutting back the stem to the base of the plant.

Overwintering

In colder climates, Calla summer sun may need to be protected from freezing temperatures. Dig up the corms after the first hard frost and store them in a cool, dry place until spring.

Common Pests and Diseases

Aphids

Aphids are small, soft-bodied insects that feed on plant sap. Control aphids by spraying with insecticidal soap or horticultural oil.

Thrips

Thrips are tiny, slender insects that feed on plant tissues. They can be controlled by spraying with insecticidal soap or neem oil.

Root Rot

Root rot is a fungal disease that can cause the roots of the plant to rot. Avoid overwatering and ensure the soil is well-draining to prevent root rot.

There are numerous varieties of Calla summer sun available, each with its own unique characteristics.

• ‘Yellow Calypso’: Large, fragrant yellow flowers with dark green foliage.
