Calla lilies, with their elegant trumpet-shaped blossoms, are a symbol of beauty and have deep roots in African culture, especially in South Africa where they originate. These attractive flowers have adapted to varying environments, allowing them to be revered both as outdoor perennials in warm climates and as beloved indoor plants in cooler regions. Their versatility, however, doesn’t exempt them from the challenges of proper care, which can lead to a common issue many gardeners encounter: drooping.
In my experience, the drooping of calla lilies is more than a mere aesthetic concern; it’s an indication of the plants’ health. Numerous factors contribute to this condition, ranging from watering habits to diseases. It’s crucial to observe the plants carefully and assess their growing conditions to pinpoint the exact cause. Whether it’s due to environmental stressors or cultivation missteps, understanding the underlying reasons can help rectify the issue and restore the lilies to their iconic stature.
The drooping of calla lilies can be caused by both underwatering and overwatering, excessively sunny conditions, root rot, and even the natural weight of their flowers.

Optimal Conditions for Calla Lily Growth
Calla lilies flourish when provided with the right balance of light, temperature, and moisture. I’ll outline the essentials to ensure these elegant blooms thrive in your garden or home.
Understanding Light and Temperature Needs
Calla lilies enjoy a warm environment with temperatures ranging between 60-75°F. In terms of lighting, these plants thrive in full sun to partial shade. I find that my calla lilies do best with morning sunlight and afternoon shade, especially in areas with hotter climates, to prevent the leaves from scorching.
💥 Light & Temp: Full sun in the morning; partial shade in the afternoon. Ideal temps are 60-75°F.
Soil Composition and Drainage
Successful growth of calla lilies hinges on well-draining soil. These plants do not tolerate “wet feet,” meaning that overly saturated roots can lead to rot. I mix my potting soil with perlite or sand to enhance drainage. Ensuring that the pot has sufficient drainage holes is also critical.
💥 Soil Needs: Well-draining soil is crucial. Amend with perlite or sand for best results.
The Role of Humidity and Air Circulation
Calla lilies enjoy a bit of humidity but not to the extent that the air becomes stagnant. My experience tells me that a balance must be struck. While appreciating moisture in the air, these flowers also need good air circulation to help prevent fungal diseases. I sometimes use a small fan to gently circulate air in indoor environments, which seems to do the trick.

Watering and Feeding Your Calla Lilies
Proper watering and fertilization are crucial for the health of calla lilies. I will discuss how to maintain the right soil moisture and choose an appropriate fertilizer to prevent your calla lilies from drooping.
Balancing Moisture: Avoiding Overwatering and Underwatering
Calla lilies thrive in moist soil, but it’s essential to avoid both overwatering and underwatering. I always check the soil before watering by inserting my finger about an inch deep. If the soil feels dry, it’s time to water. Conversely, if the soil is wet, I wait for the top inch to dry out before watering again. This prevents issues of root rot associated with too much moisture and the wilting that occurs from dry conditions.
- Water when the top inch of soil is dry.
- Reduce watering in the dormant season.
- Avoid letting the soil become completely dry.
Choosing the Right Fertilizer
The right fertilizer aids in the robust growth of calla lilies without causing droop. I prefer using a balanced fertilizer that does not have an excessive nitrogen content. High levels of nitrogen can promote foliage over flowers and lead to the drooping of plants. Feeding should occur during the growing season, following the instructions on the fertilizer packaging for the correct application rate.
- Balanced N-P-K ratio, like 10-10-10 or 5-10-5.
- Slow-release formulas for sustained nutrition.
- Avoid high nitrogen fertilizers to prevent drooping.
Common Issues and Their Remedies
When your calla lilies begin to droop, it may be disheartening. However, identifying the exact problem is the first step to reviving your beloved blooms. I’ll highlight some usual culprits and provide effective fixes to get your calla lilies standing tall.
Identifying and Treating Diseases
If your calla lilies exhibit drooping or mushy stems, it could be due to soft rot, a fungal disease.
Soft rot and fungal diseases like Anthracnose can cause drooping. I take immediate action to remove affected parts and apply fungicides, ensuring good air circulation to prevent these diseases.
Addressing Pest Problems
Pests like aphids, spider mites, and thrips can stress calla lilies, causing leaves to wilt. I check regularly for these pests and treat them promptly with insecticidal soap or neem oil.
Fixing Physical and Environmental Stressors
Calla lilies are prone to drooping due to environmental and physical stressors. Here’s how I tackle common issues:
💥 Dehydration and Overwatering
- Dehydration can dry soil and cause wilting. I ensure to water the lilies sufficiently.
- Overwatering leads to root rot; thus, I maintain a balance, letting the soil dry slightly between watering.
💥 Light and Temperature
- Insufficient light stunts growth, so I place them in bright, indirect sunlight.
- Calla lilies react poorly to sudden temperature changes, particularly in winter. I protect them from drafts and drastic temperature swings.
Avoid over-fertilizing as it can contribute to drooping and general plant stress.
Maintaining these parameters keeps my calla lilies healthy and upright.
Caring for Calla Lilies Throughout the Year
Caring for calla lilies involves understanding the seasonal needs of these attractive plants, ensuring they’re pruned, potted correctly, and maintain health throughout the year.
Seasonal Care Tips
In spring, I ensure the risk of frost has passed before planting calla lily rhizomes. They prefer a spot with bright, indirect light and a moderate watering routine to prevent root rot.
In the hot summer months, calla lilies often bloom, requiring frequent watering but always making sure the soil drains well to keep roots from staying mushy. I stress the importance of proper drainage, especially if unexpected heavy rainfall occurs.
When fall approaches, I lessen watering and prepare the plants for dormancy in winter. I ensure they’re shielded from severe cold, especially in zones where they are not hardy.
Pruning and Repotting for Healthy Growth
Pruning is essential for preventing disease and encouraging new growth. I remove only the dead or yellowing leaves with pruning shears, being cautious not to cut any new growth.
For repotting, I choose spring before new growth starts. An unglazed pot is ideal since it allows the soil to breathe, aiding in moisture regulation.
Always ensure that bulbs or rhizomes are not sitting in waterlogged soil after repotting to prevent the onset of root rot.
