The calla lily, with its trumpet-shaped blooms and glossy leaves, is a stunning addition to any garden. But can a calla lily be planted outside? The answer, like many things in gardening, is a bit more nuanced than a simple yes or no. While these lilies can thrive outdoors in certain climates, they require specific conditions to flourish. This guide will delve into the factors that determine whether your calla lily can thrive in your outdoor garden.
Understanding Calla Lily Needs
Calla lilies, scientifically known as Zantedeschia, are native to South Africa and prefer warm, humid environments. They are considered tender perennials, meaning they can’t tolerate freezing temperatures. This makes their suitability for outdoor planting highly dependent on your geographic location and the specific variety of calla lily you choose.
Climate and Calla Lilies: A Match Made in Heaven?
The ideal climate for outdoor calla lily cultivation is one with warm summers and mild winters, free from frost. USDA hardiness zones 8-10 are generally considered suitable for growing calla lilies outdoors year-round. However, even within these zones, microclimates and specific locations can influence their survival.
Calla Lily Varieties: Choosing the Right Fit
Not all calla lilies are created equal. Some varieties are more tolerant of cooler temperatures than others. For example, the “Black Magic” calla lily, with its deep purple blooms, is known for its cold hardiness compared to other varieties.
Outdoor Planting: A Step-by-Step Guide
If your climate allows, planting calla lilies outdoors can be a rewarding experience. Here’s a step-by-step guide:
1. Choose the Right Location: Select a spot that receives partial shade, especially in hot climates. Calla lilies prefer moist soil and will thrive in areas with some protection from the midday sun.
2. Prepare the Soil: Calla lilies thrive in rich, well-drained soil. Amend your soil with compost or other organic matter to improve drainage and fertility.
3. Planting Time: The best time to plant calla lilies outdoors is in spring after the last frost.
4. Spacing and Depth: Space your calla lily bulbs 12-18 inches apart. Plant the bulbs with the pointed end facing upwards, about 4-6 inches deep.
5. Watering and Care: Water your calla lilies regularly, especially during dry periods. They appreciate consistent moisture. Fertilize with a balanced fertilizer every few weeks during the growing season.
Overwintering Calla Lilies: Bringing Them Indoors
If you live in a climate that experiences frost, you’ll need to bring your calla lilies indoors for the winter. Here’s how:
1. Dig Up the Bulbs: In late fall, before the first frost, dig up your calla lily bulbs.
2. Clean and Dry: Gently brush off excess soil and allow the bulbs to air dry in a cool, dry place for a few days.
3. Storage: Store the bulbs in a cool, dark, and dry location, such as a basement or garage.
4. Replanting: In spring, after the last frost, you can replant the bulbs outdoors.
Calla Lilies in Containers: A Versatile Option
For regions with colder climates or for those who prefer the flexibility of container gardening, growing calla lilies in pots is an excellent option.
1. Choose the Right Pot: Select a pot with drainage holes and a size that allows for adequate root growth.
2. Prepare the Potting Mix: Use a well-draining potting mix enriched with organic matter.
3. Planting: Plant the bulbs in the pot, with the pointed end facing upwards, and cover them with potting mix.
4. Watering and Care: Water the potted calla lilies regularly, keeping the soil consistently moist. Fertilize every few weeks during the growing season.
Calla Lily Care: Tips for Success
To ensure your calla lilies thrive, follow these additional care tips:
- Deadheading: Remove spent flowers to encourage new blooms.
- Pest and Disease Control: Monitor for pests and diseases and treat them promptly.
- Winter Protection: If you live in a borderline climate, consider providing winter protection to your outdoor calla lilies with mulch or a layer of straw.
