1. Cut off rotten rootsIf the leaves of Calla Lily suddenly fall over, there may be a problem with the roots. If you find any blackening or rot, you need to cut them off in time, remove the blackened and rotten parts, place them in a disinfectant solution for disinfection, then wash them with clean water, place them aside to dry, apply rooting agent, and replant and maintain them.2. Adjust the water levelIt may also be affected by the water level. If the water level is too high, the coverage area will be larger, which can easily lead to rot. The growth of the leaves will also be affected, causing the leaves to become soft and fall. Try to choose a larger water tank. When adding water, pay attention to the amount of water. The water level does not need to be too high and should be flat and stable. If the water is too deep, some of it needs to be poured out.3. Adjust the water temperatureCalla lily likes to grow in a warm climate environment and is sensitive to water temperature. 15-24℃ is more suitable and it grows more vigorously. If the temperature is low for a long time, the respiration of the roots will be affected, the absorption of nutrients and water will be weakened, and it is easy to cause yellow leaves to fall over. Protect Calla Lily in winter, the temperature should not be lower than 5℃, it can be moved indoors and buried below the permafrost layer. |
