Before attempting to revive a dying calla lily, carefully examine its current state. Look for yellowing leaves, wilting stems, root rot, or pest infestations. Calla lilies may decline due to improper watering, insufficient light, or nutrient deficiencies. Identifying the root cause is essential for effective revival.
Calla lilies prefer consistently moist but not waterlogged soil. Overwatering can lead to root rot, while underwatering causes dehydration. If the soil is soggy, reduce watering frequency and ensure proper drainage. If the soil is dry, increase hydration gradually. Water deeply until excess drains out, but avoid letting the plant sit in standing water.
Calla lilies thrive in bright, indirect light. If the plant is in deep shade or direct scorching sunlight, relocate it to a spot with filtered light. Insufficient light weakens growth, while excessive sun can scorch leaves. Adjusting light conditions helps the plant recover and produce healthy foliage.
Poor soil can starve the plant of essential nutrients. Use a well-draining, peat-based potting mix enriched with organic matter. If the plant shows signs of nutrient deficiency (e.g., pale leaves), apply a balanced liquid fertilizer diluted to half strength every 4-6 weeks during the growing season. Avoid over-fertilizing, which can burn roots.
Gently remove the plant from its pot to inspect the roots. Healthy roots are firm and white, while rotten roots are mushy and brown. Trim damaged roots with sterilized scissors and repot the plant in fresh soil. If root rot is severe, propagate healthy rhizomes instead of saving the entire plant.
Common pests like aphids, spider mites, or fungal infections can weaken calla lilies. Wipe leaves with a damp cloth or use insecticidal soap for pests. For fungal issues, remove affected foliage and apply a fungicide. Ensure good air circulation to prevent future infestations.
Trim yellow or brown leaves to redirect the plant's energy toward new growth. Use clean, sharp shears to avoid spreading disease. Pruning also improves airflow, reducing the risk of fungal infections.
Calla lilies prefer temperatures between 60-75°F (15-24°C) and moderate humidity. Avoid placing them near drafts or heating vents. If indoor air is dry, use a humidity tray or mist the plant occasionally to mimic its natural environment.
After flowering, calla lilies enter a dormant phase where leaves naturally yellow and die back. Reduce watering and allow the plant to rest. Store rhizomes in a cool, dark place if grown outdoors in cold climates. Resume care when new growth appears.
Revival takes time. Continue providing optimal care and observe the plant's response. New shoots indicate recovery, while persistent decline may require propagation or replacement.
