How to Look After Calla Lily Houseplants: Expert Advice for Beautiful Blooms
What To Know
- If you only have a south or west-facing window, ensure the plant is positioned at least 3 feet away from the glass.
- Overwatering is a common mistake that can lead to root rot, so it’s crucial to strike a balance.
- You can increase humidity by grouping your plants together, placing a humidifier nearby, or placing the pot on a tray filled with pebbles and water.
Calla lilies, with their elegant trumpet-shaped flowers and vibrant colors, are a popular choice for indoor plant enthusiasts. However, knowing how to look after calla lily houseplant is key to enjoying their beauty year after year. This comprehensive guide will equip you with the knowledge and techniques to cultivate healthy and flourishing calla lilies in your home.
Understanding the Needs of Your Calla Lily
Calla lilies, scientifically known as Zantedeschia, are native to South Africa, where they thrive in moist, subtropical environments. To successfully cultivate them indoors, it’s crucial to recreate these conditions. Here’s a breakdown of their essential requirements:
Light: The Source of Life
Calla lilies thrive in bright, indirect light. Avoid direct sunlight, as it can scorch their delicate leaves. An east-facing window, providing morning sun, is ideal. If you only have a south or west-facing window, ensure the plant is positioned at least 3 feet away from the glass.
Water: The Lifeblood of Growth
Calla lilies are thirsty plants, requiring consistent moisture. The soil should be kept evenly moist, but not waterlogged. Allow the top inch of soil to dry out between waterings. Overwatering is a common mistake that can lead to root rot, so it’s crucial to strike a balance.
Temperature: The Comfort Zone
Calla lilies prefer temperatures between 60°F and 75°F (15°C to 24°C). Avoid placing them near drafts or cold windows, as sudden temperature fluctuations can stress the plant.
Humidity: The Tropical Touch
Calla lilies appreciate humid environments. You can increase humidity by grouping your plants together, placing a humidifier nearby, or placing the pot on a tray filled with pebbles and water.
Nurturing Your Calla Lily: Essential Care Practices
Fertilizing: A Boost for Blooms
During the growing season (spring and summer), fertilize your calla lily every two weeks with a balanced liquid fertilizer diluted to half strength. Avoid over-fertilizing, as it can burn the roots. During the dormant period (fall and winter), reduce fertilization to once a month.
Repotting: Providing Room to Grow
Calla lilies are vigorous growers and may require repotting every year or two. Choose a pot that is slightly larger than the previous one, ensuring adequate drainage with drainage holes. Use a well-draining potting mix designed for flowering plants.
Pruning: Maintaining a Healthy Shape
Pruning is essential for maintaining a healthy and attractive calla lily. Remove any dead or yellowing leaves as they appear. After flowering, cut back the flower stalks to encourage new growth.
Troubleshooting Common Calla Lily Problems
While calla lilies are generally hardy plants, they can be susceptible to certain problems. Here’s a guide to identifying and addressing common issues:
Yellowing Leaves: A Sign of Stress
Yellowing leaves can indicate several issues, including overwatering, underwatering, insufficient light, or nutrient deficiencies. Inspect the soil moisture, adjust watering frequency, and ensure adequate light exposure. If the problem persists, consider a balanced fertilizer.
Brown Spots on Leaves: A Sign of Disease
Brown spots on leaves can be a sign of fungal or bacterial diseases. Improve air circulation around the plant, avoid overwatering, and remove any affected leaves. Consider using a fungicide or bactericide if necessary.
Lack of Blooming: A Sign of Improper Care
Calla lilies may not bloom if they are not receiving enough light, water, or nutrients. Ensure they are exposed to bright, indirect light, watered consistently, and fertilized regularly. Also, ensure the plant is not overcrowded in its pot.
The Art of Propagation: Expanding Your Calla Lily Collection
Calla lilies can be easily propagated through division. During repotting, carefully separate the plant into smaller divisions, ensuring each division has at least one growth point (bud). Repot the divisions in fresh potting mix, and water them thoroughly.
Embracing the Dormant Period: A Time for Rest
Calla lilies enter a dormant period in the fall and winter. During this time, the foliage may yellow and die back. Reduce watering to once a month and cease fertilization. Place the plant in a cool, dark location. The dormant period is essential for the plant to conserve energy and prepare for the next growing season.
Reawakening Your Calla Lily: Springtime Revival
As spring approaches, your calla lily will begin to emerge from dormancy. Gradually increase watering and fertilization, and move the plant to a brighter location. Within a few weeks, you should see new growth and eventually, vibrant flowers.
Beyond the Basics: Tips for Advanced Calla Lily Care
Pest Control: Protecting Your Plant
Calla lilies are susceptible to pests such as aphids, mealybugs, and spider mites. Inspect your plant regularly for signs of infestation. If you discover pests, use insecticidal soap or neem oil to control them.
Disease Prevention: Maintaining a Healthy Environment
Provide optimal growing conditions to prevent diseases. Avoid overwatering, ensure good air circulation, and use sterile potting mix. If you suspect a disease, remove any affected leaves and consider using a fungicide or bactericide.
A Farewell to Your Calla Lily: A Final Touch
As your calla lily reaches the end of its life cycle, it may be time to say goodbye. You can either discard the plant or try to propagate it. If you choose to discard it, ensure you dispose of it properly, as some parts of the plant can be toxic to pets and children.

A: The best time to repot a calla lily is during the dormant period (fall and winter) when the plant is not actively growing.
Q: Can I grow calla lilies outdoors?
A: Calla lilies can be grown outdoors in warm climates, but they are generally considered indoor plants. If you live in a region with cold winters, you will need to bring your calla lily indoors during the winter months.
Q: What is the best way to prevent root rot in calla lilies?
A: To prevent root rot, ensure the soil is well-draining and avoid overwatering. Allow the top inch of soil to dry out between waterings.
Q: What are the signs of a calla lily being overwatered?
A: Signs of overwatering include yellowing leaves, wilting, and a mushy or soggy soil.
Q: Why is my calla lily not blooming?
A: Several factors can prevent a calla lily from blooming, including insufficient light, water, or nutrients, overcrowding in the pot, or a lack of dormancy. Ensure the plant is receiving optimal care and conditions.
