Calla lilies require consistent moisture but should not be overwatered. Water the plants when the top inch of soil becomes dry. Use a soaker hose or drip irrigation system to deliver water directly to the roots, preventing water from splashing on the leaves and reducing the risk of fungal diseases. In hot, dry climates, water calla lilies more frequently to maintain consistently moist soil.
Avoiding Overwatering and Underwatering
Overwatering can lead to root rot and other fungal diseases, while underwatering can cause the leaves to wilt and the flowers to fade. To prevent overwatering, ensure the soil has adequate drainage and avoid watering the plants if the soil is still moist. To prevent underwatering, monitor the soil moisture regularly and water the plants as needed. If you are unsure whether your calla lilies need watering, wait a day or two to observe any changes in the soil or plant appearance.
Fertilizing Calla Lilies
Calla lilies benefit from regular fertilization, which provides essential nutrients for optimal growth. Use a balanced, water-soluble fertilizer with a ratio of 10-10-10 (nitrogen-phosphorus-potassium) or a fertilizer specifically formulated for calla lilies. Apply the fertilizer every 2-4 weeks during the growing season, following the manufacturer’s instructions for the recommended application rate.
Best Fertilizers and Application Schedules
When selecting a fertilizer, choose a product with a slow-release formula, which provides a steady supply of nutrients over an extended period. Alternatively, use a liquid fertilizer, which can be easily diluted and applied through a watering can or drip irrigation system. Apply the fertilizer at the beginning of the growing season, then every 2-4 weeks thereafter, adjusting the frequency based on the plant’s response and the manufacturer’s recommendations.
By understanding the watering needs and fertilization requirements of calla lilies, you can provide the necessary care for these elegant blooms to thrive. Regularly monitor your calla lilies for any changes in their appearance or health, and address any issues promptly to maintain their overall well-being.
