The calla lily, with its elegant trumpet-shaped blooms and striking foliage, is a popular choice for gardens and homes alike. But did you know that these beauties are surprisingly low-maintenance? While not exactly “set it and forget it” plants, understanding their needs isn’t rocket science.
This guide will walk you through the essential steps on how to care for calla lilies, from choosing the right location to ensuring proper watering and fertilization. We’ll even touch on common problems and how to address them, so you can enjoy their stunning beauty for years to come.
Understanding the Calla Lily: A Brief Overview
Calla lilies, scientifically known as Zantedeschia, are not true lilies but rather members of the Araceae family. They are native to South Africa and are popular for their distinctive flowers, which are actually modified leaves called spathes. These spathes come in a stunning array of colors, from classic white to vibrant shades of pink, yellow, orange, and even purple.
Light and Location: Finding the Perfect Spot for Your Calla Lily
Calla lilies thrive in bright, indirect light, especially during their growing season. While they can tolerate some direct sunlight, especially in the morning hours, prolonged exposure can scorch their leaves.
Ideal Indoor Location
If you’re growing calla lilies indoors, place them near a window that receives ample sunlight, but avoid direct sunlight, especially during the hottest part of the day. You can also use artificial light sources, such as grow lamps, to supplement natural light, especially during winter months.
Outdoor Location
When growing calla lilies outdoors, choose a location that receives partial shade, especially during the hottest part of the day. A spot under a tree or a shaded patio is ideal.
Watering: Striking the Right Balance
Watering is crucial for the health of your calla lilies. They prefer consistently moist soil, but overwatering can lead to root rot.
Watering Frequency
Water your calla lilies thoroughly when the top inch of soil feels dry to the touch. During the growing season, this may mean watering every few days, while in winter, you can water less frequently.
Drainage
Ensure that the pot has drainage holes to prevent water from accumulating at the base of the plant. Allow excess water to drain away freely.
Soil: The Foundation for Healthy Growth
Calla lilies prefer a well-draining soil that is rich in organic matter.
Ideal Soil Mix
A good mix for calla lilies consists of equal parts potting soil, peat moss, and perlite. This combination provides the necessary drainage and aeration while retaining moisture.
Soil pH
Calla lilies thrive in slightly acidic soil with a pH range of 6.0 to 6.5. You can adjust the pH by adding a small amount of sulfur to the soil.
Fertilization: Providing Essential Nutrients
Regular fertilization is essential for healthy growth and abundant blooms.
Fertilizer Type
Use a balanced liquid fertilizer specifically formulated for flowering plants. Follow the instructions on the label carefully.
Fertilizing Frequency
Fertilize your calla lilies every two weeks during the growing season (spring and summer). Reduce fertilization during the winter months when the plant is dormant.
Propagation: Expanding Your Calla Lily Collection
Calla lilies can be propagated through division or by planting their seeds.
Division
Divide the tubers of your calla lily plant in the spring before new growth emerges. Carefully separate the tubers and replant them in fresh potting mix.
Seeds
Sow calla lily seeds in a seed tray filled with a light, well-draining potting mix. Keep the soil moist and warm. Germination can take several weeks.
Pruning: Maintaining a Neat and Healthy Appearance
Pruning your calla lily plant is essential for maintaining its shape and promoting new growth.
Deadheading
Regularly remove spent blooms to encourage the plant to produce more flowers.
Leaf Removal
Remove any yellowing or damaged leaves to prevent diseases and maintain a healthy appearance.
Winter Dormancy: Resting for a New Season
Calla lilies enter a period of dormancy in winter, during which they require less water and light.
Dormancy Care
Reduce watering during winter and allow the soil to dry out slightly between waterings. Store the plant in a cool, dark place, such as a basement or garage.
Re-emergence
In spring, when new growth emerges, gradually increase watering and bring the plant back to a bright location.
Common Problems and Their Solutions
While calla lilies are relatively easy to care for, they can be susceptible to a few common problems.
Pests
Aphids, mealybugs, and spider mites can infest calla lilies. Use insecticidal soap or neem oil to control these pests.
Diseases
Calla lilies can be affected by fungal diseases such as leaf spot and root rot. Ensure good drainage and avoid overwatering to prevent these problems.
Yellowing Leaves
Yellowing leaves can be a sign of overwatering, underwatering, or nutrient deficiencies. Adjust your watering practices and fertilize as needed.
The Grand Finale: A Successful Calla Lily Journey
By following these simple tips, you can create a thriving environment for your calla lilies. With proper care, they will reward you with their elegant blooms and graceful foliage, adding a touch of beauty and sophistication to your home or garden.

A: Maintaining good hygiene, including removing dead leaves and stems, and providing adequate air circulation can help prevent pests and diseases.
Q: Can I force calla lilies to bloom indoors during winter?
A: Yes, you can force calla lilies to bloom indoors during winter by bringing them inside to a bright location and providing them with consistent watering and fertilization.
Q: How do I know when my calla lily is dormant?
A: The leaves will start to yellow and die back, and the plant will stop producing new growth. This is a natural process and should not be a cause for concern.
