Calla lilies, with their elegant, trumpet-shaped flowers and lush, green foliage, are a favorite among gardeners. But can you plant a potted calla lily outside? The answer is a resounding yes. This article will guide you through the process, providing expert advice and tips to ensure your calla lilies thrive in their new outdoor home.
Understanding Calla Lilies
Before we delve into the planting process, it’s important to understand a bit more about calla lilies. Native to South Africa, these perennials are known for their hardiness and adaptability. They can grow in a variety of conditions, from full sun to partial shade, and are relatively easy to care for.
According to the USDA, calla lilies are hardy in zones 8-10. This means they can withstand temperatures as low as 10-15 degrees Fahrenheit. However, in colder climates, they can be grown as annuals or overwintered indoors.
Types of Calla Lilies
There are numerous varieties of calla lilies, each with its own unique characteristics. Some popular types include:
- Zantedeschia aethiopica: Also known as the common calla lily, this variety is known for its large, white flowers.
- Zantedeschia elliottiana: This variety boasts yellow flowers and spotted leaves.
- Zantedeschia rehmannii: This type features slender, pink flowers.
Choosing the right variety for your garden depends on your personal preferences and the specific conditions of your outdoor space.
How to Plant a Potted Calla Lily Outside
Now that we’ve covered some background information, let’s move on to the main event: planting your potted calla lily outside. Here’s a step-by-step guide:
- Choose the right location: Calla lilies prefer a spot with full sun or partial shade. They also need well-drained soil.
- Prepare the soil: Amend the soil with organic matter, such as compost or well-rotted manure, to improve its fertility and drainage.
- Remove the lily from the pot: Carefully take the lily out of its pot, making sure not to damage the roots.
- Plant the lily: Dig a hole that’s about twice the size of the lily’s root ball. Place the lily in the hole, making sure the top of the root ball is level with the soil surface. Backfill with soil and firm it gently around the base of the plant.
- Water the lily: After planting, water the lily thoroughly.
Remember, the best time to plant calla lilies outside is in the spring, after the threat of frost has passed.
Caring for Your Outdoor Calla Lily
Once your calla lily is happily settled in its new outdoor home, it’s important to provide the right care to ensure it thrives. Here are some key tips:
- Watering: Calla lilies need regular watering, but be careful not to overwater. The soil should be kept moist, but not waterlogged.
- Fertilizing: Feed your calla lily with a balanced fertilizer every two weeks during the growing season.
- Mulching: Apply a layer of mulch around the base of the plant to help conserve moisture and suppress weeds.
- Pruning: Remove spent flowers to encourage more blooms. In the fall, cut back the foliage after it has died back.
With the right care, your outdoor calla lily can provide you with a stunning display of flowers year after year.
Common Problems and Solutions
While calla lilies are relatively easy to grow, they can sometimes encounter problems. Here are some common issues and how to deal with them:
Pests
Calla lilies can be affected by pests such as aphids and slugs. Aphids can be controlled with insecticidal soap, while slugs can be deterred with a ring of crushed eggshells or diatomaceous earth around the base of the plant.
Diseases
Calla lilies can also be susceptible to diseases such as root rot and bacterial soft rot. Both of these can be prevented by ensuring your lily is planted in well-drained soil and not overwatered.
Conclusion
So, can you plant a potted calla lily outside? Absolutely. With the right location, proper planting, and appropriate care, your calla lily can thrive in its outdoor home, providing you with a stunning display of flowers for many seasons to come. Happy gardening!
