Unlocking the Mystery: Can Calla Lily Be Planted in the Ground? Find Out Now!

Calla lilies, with their elegant trumpet-shaped flowers and lush foliage, are a beloved addition to gardens worldwide. But can these stunning blooms thrive in the ground, or are they best suited for containers? Let’s delve into the world of calla lilies and explore the best ways to cultivate these captivating plants.

The Beauty of Calla Lilies

Calla lilies, scientifically known as Zantedeschia, are not true lilies but rather belong to the Arum family. They are native to South Africa and are prized for their striking flowers, which come in a range of colors, from classic white to vibrant shades of yellow, pink, orange, and even purple. These flowers are actually modified leaves called spathes, which surround the true flower, a tiny spadix that sits in the center.

Calla Lilies: Ground Dwellers or Container Queens?

The answer to the question “Can calla lily be planted in the ground?” is a resounding yes! Calla lilies can indeed be grown successfully in the ground, especially in regions with mild climates. However, there are a few factors to consider before making your decision:

Climate Considerations

Calla lilies are generally frost-tender, preferring temperatures above 50°F (10°C). In areas with cold winters, they are best treated as annuals or grown in containers that can be brought indoors during the colder months. However, in warmer climates with mild winters, calla lilies can be planted directly in the ground and will return year after year.

Soil Preferences

Calla lilies thrive in rich, well-draining soil that is slightly acidic to neutral (pH 6.0-7.0). They prefer moist conditions but can be susceptible to root rot if the soil is too wet. Adding organic matter like compost or peat moss to your soil can improve drainage and fertility.

Sunlight Requirements

Calla lilies enjoy partial shade to full sun, especially in hot climates. In areas with cooler temperatures, they can tolerate more sun. Aim for a location that receives at least 4 hours of sunlight per day.

Planting Calla Lilies in the Ground

If you’re ready to plant your calla lilies in the ground, follow these steps:

1. Choose the right location: As mentioned above, select a spot that receives at least 4 hours of sunlight per day and has well-draining soil.
2. Prepare the soil: Amend your soil with compost or peat moss to improve drainage and fertility.
3. Plant the tubers: Dig a hole about 4-6 inches deep and 6-8 inches wide. Place the tuber with the pointy end facing upward and cover it with soil. Space tubers 12-18 inches apart.
4. Water thoroughly: After planting, water your calla lilies deeply to help establish the roots.
5. Mulch: Apply a layer of mulch around the plants to help retain moisture and suppress weeds.

Caring for Ground-Planted Calla Lilies

Once your calla lilies are established, they require minimal care. Here’s what you need to know:

Watering

Calla lilies need consistent moisture, especially during the growing season. Water deeply once or twice a week, allowing the top inch of soil to dry out between waterings. Avoid overwatering, which can lead to root rot.

Fertilizing

Feed your calla lilies with a balanced liquid fertilizer every 2-4 weeks during the growing season. Avoid fertilizing during the dormant period.

Deadheading

Deadhead spent flowers by snipping them off at the base. This will encourage the plant to produce more blooms.

Dormancy

In colder climates, calla lilies will go dormant in the fall. Cut back the foliage and leave the tubers in the ground. They will re-emerge in the spring.

Calla Lilies: A Touch of Elegance in Your Garden

Calla lilies are a beautiful and relatively easy-to-grow plant that can add a touch of elegance to any garden. Whether you choose to plant them in containers or directly in the ground, these stunning blooms are sure to impress. Remember to consider your climate, soil type, and sun exposure when making your decision.
