Calla lilies thrive in consistently moist soil. If the soil becomes too dry, the plant will start to droop as a survival mechanism to conserve water. The leaves and stems lose their turgidity, causing them to wilt. To fix this, water the plant deeply until the soil is evenly moist but not waterlogged. Ensure proper drainage to prevent root rot while maintaining adequate moisture levels.
While calla lilies need moisture, overwatering or poorly draining soil can suffocate the roots, leading to drooping. Soggy soil prevents oxygen from reaching the roots, causing root rot, which weakens the plant. Check the soil before watering—if it feels wet, delay watering. Repot the plant in well-draining soil and ensure the pot has drainage holes to avoid water accumulation.
Calla lilies prefer temperatures between 60-75°F (15-24°C). Exposure to extreme heat or cold can cause stress, leading to drooping leaves. High temperatures increase transpiration, while cold drafts or frost damage cell tissues. Move the plant to a stable environment, away from heaters, air conditioners, or open windows during temperature extremes.
Native to tropical regions, calla lilies require moderate to high humidity. Dry air causes the leaves to lose moisture faster than the roots can absorb, resulting in drooping. Increase humidity by misting the leaves, placing a humidifier nearby, or setting the pot on a tray filled with pebbles and water (ensuring the pot isn’t submerged).
A lack of essential nutrients, particularly nitrogen, potassium, or phosphorus, can weaken the plant, causing drooping. Yellowing leaves often accompany nutrient deficiencies. Feed the calla lily with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season. Avoid over-fertilizing, as salt buildup can harm the roots.
If the calla lily has outgrown its pot, the roots may become cramped, restricting water and nutrient uptake. This leads to drooping and stunted growth. Check the root system—if roots are circling the pot or growing through drainage holes, repot the plant into a larger container with fresh soil.
Infestations by aphids, spider mites, or fungal infections like powdery mildew can stress the plant, causing drooping. Inspect the leaves and stems for pests or discoloration. Treat pests with insecticidal soap or neem oil, and remove affected foliage. For fungal issues, improve air circulation and avoid wetting the leaves when watering.
Calla lilies enter a dormant phase after flowering, usually in late fall or winter. During this time, the leaves may yellow and droop as the plant conserves energy. Reduce watering and allow the foliage to die back naturally. Resume regular care when new growth appears in spring.
Recently repotted or divided calla lilies may droop due to transplant shock. The roots need time to adjust to the new environment. Minimize stress by keeping the plant in a shaded, stable location and maintaining consistent moisture. Avoid fertilizing until the plant shows signs of recovery.
Too much direct sunlight can scorch the leaves, while insufficient light weakens the plant. Calla lilies prefer bright, indirect light. If drooping occurs with sunburned leaves, move the plant to a shadier spot. If the stems are leggy and weak, provide more filtered sunlight.
