Discover the Secret to Planting Calla Lilies Outside: Essential Tips and Tricks
What To Know
- Dig a hole twice the width of the Calla lily bulb and as deep as the bulb itself.
- Mix in a generous amount of compost or peat moss to enrich the soil and improve drainage.
- Gently cover the bulb with soil, making sure the top of the bulb is slightly below the soil level.
The elegant, trumpet-shaped blooms of the Calla lily (Zantedeschia) are a stunning addition to any garden. Their graceful, almost ethereal presence adds a touch of sophistication and charm to landscapes. But knowing how to plant calla lily outside is essential to ensure they thrive and reward you with their beauty year after year. This comprehensive guide will walk you through each step, from choosing the right location to nurturing your calla lilies for optimal growth.
Understanding Calla Lily Varieties
Before we delve into the planting process, it’s crucial to understand the different types of Calla lilies. There are two primary categories:
- Hardy Calla Lilies: These varieties, such as Zantedeschia aethiopica, are known for their resilience and ability to withstand colder temperatures. They can tolerate frost and even survive in USDA hardiness zones 7-10.
- Tender Calla Lilies: These include varieties like Zantedeschia rehmannii and Zantedeschia elliottiana, which prefer warmer climates. They are typically grown as annuals in colder regions or require protection during winter.
Knowing the specific type of Calla lily you’re planting will determine your planting strategy and care routine.
Choosing the Perfect Spot
Calla lilies thrive in moist, well-drained soil with partial shade. Here’s how to find the ideal location:
- Sunlight: While Calla lilies prefer dappled shade, they can tolerate full sun, especially in cooler climates. However, avoid planting them in scorching hot areas where the soil might dry out quickly.
- Soil: The soil should be rich in organic matter and have good drainage. Before planting, amend the soil with compost or peat moss to improve its structure and fertility.
- Water: Calla lilies require consistent moisture. Choose a location that receives regular rainfall or has access to irrigation.
Preparing for Planting
Once you’ve selected the perfect spot, it’s time to prepare the soil for your Calla lilies:
- Dig a Hole: Dig a hole twice the width of the Calla lily bulb and as deep as the bulb itself.
- Amend the Soil: Mix in a generous amount of compost or peat moss to enrich the soil and improve drainage.
- Space the Bulbs: Space the bulbs about 12 inches apart to allow for adequate growth.
Planting Your Calla Lily Bulbs
Now that your location is prepared, it’s time to plant your Calla lily bulbs:
- Position the Bulb: Place the bulb in the hole with the pointed end facing upwards.
- Backfill the Hole: Gently cover the bulb with soil, making sure the top of the bulb is slightly below the soil level.
- Water Thoroughly: Water the newly planted bulbs deeply to settle the soil and encourage root development.
Nurturing Your Calla Lilies
After planting, it’s essential to provide your Calla lilies with the right care to ensure they thrive:
- Watering: Calla lilies need consistent moisture, especially during the growing season. Water them regularly, ensuring the soil remains moist but not waterlogged.
- Fertilizing: Feed your Calla lilies with a balanced fertilizer every few weeks during the growing season. This will provide them with the nutrients needed for healthy growth and blooming.
- Deadheading: Remove spent flowers to encourage further blooming.
- Winter Care: Hardy Calla lilies can withstand winter temperatures in their designated zones. However, you might need to mulch them for added protection. Tender Calla lilies require overwintering indoors in a cool, dry place.
A Celebration of Bloom: Enjoying Your Calla Lilies
With proper care, your Calla lilies will reward you with their exquisite blooms. These graceful flowers will add a touch of elegance to your garden, attracting pollinators and brightening your landscape.
Beyond the Bloom: Propagating Calla Lilies
Calla lilies can be easily propagated through division. This method allows you to expand your collection or share these beautiful plants with others:
- Timing: The best time for division is during the dormant period, usually in late summer or early fall.
- Process: Gently dig up the clump of Calla lilies and separate the bulbs. Each bulb should have at least one healthy growth point.
- Replanting: Plant the divided bulbs in fresh soil, following the same steps outlined earlier.
Preventing Pests and Diseases
While Calla lilies are generally resistant to pests and diseases, they can occasionally be affected by:
- Aphids: These small insects can suck sap from the plants, causing stunted growth and leaf discoloration. Control them with insecticidal soap or a strong jet of water.
- Leaf Spot Diseases: These fungal diseases can cause brown or black spots on the leaves. Good air circulation and proper watering practices can help prevent them.
