Calla Lilies: A Guide to Planting Them in the Ground

Introduction

Calla lilies (Zantedeschia spp.) are beautiful, elegant flowers that can add a touch of sophistication to any garden. They are relatively easy to grow, but there are a few things you need to know about planting calla lilies in the ground to ensure success.

Varieties and Cultivars

There are many varieties of calla lilies available, each with its own unique color, shape, and size. Some popular varieties include:

• Calla ‘Black Magic’ (black flowers)
• Calla ‘Captain Nemo’ (dark purple flowers)
• Calla ‘Crystal Clear’ (white flowers)
• Calla ‘Picasso’ (yellow flowers with purple spots)

Planting Time

The best time to plant calla lilies in the ground is in the spring after the last frost. You can also plant them in the fall, but they may not bloom as well the first year.

Site Selection and Soil Preparation

Calla lilies prefer to grow in full sun to partial shade. They need well-drained soil that is rich in organic matter. Before planting, dig a hole that is twice the width of the root ball and just as deep. Loosen the soil at the bottom of the hole and add some compost or other organic matter.

Planting Instructions

1. Remove the calla lily from its container and gently loosen the roots.
2. Place the calla lily in the hole and backfill with soil, tamping down gently to remove any air pockets.
3. Water the calla lily deeply and regularly, especially during the first few weeks after planting.

Care and Maintenance

Calla lilies are relatively low-maintenance plants. Here are a few tips to help them thrive:

• Water: Calla lilies need regular watering, especially during the hot summer months. Avoid overwatering, as this can lead to root rot.
• Fertilizer: Calla lilies can benefit from a light application of fertilizer in the spring and summer. Use a balanced fertilizer, such as a 10-10-10 formula.
• Sunlight: Calla lilies prefer to grow in full sun to partial shade. In hot climates, afternoon shade is best.
• Deadheading: Deadhead spent flowers to encourage new bloom production.
• Winter Care: Calla lilies are not hardy in cold climates. In areas where the temperature drops below freezing, you need to dig up the bulbs in the fall and store them in a cool, dark place until spring.

Troubleshooting

• Yellow leaves: Yellow leaves can be a sign of overwatering, under watering, or nutrient deficiency.
• Brown tips on leaves: Brown tips on leaves can be a sign of overwatering or under watering.
• No flowers: Calla lilies may not flower if they are not getting enough sunlight or if they are not getting enough fertilizer.

Conclusion

Calla lilies are a beautiful and relatively easy-to-grow addition to any garden. By following the tips in this guide, you can enjoy these elegant flowers for years to come.
