Description: Leaf drop in Plumeria cuttings during propagation can occur due to various factors, including environmental stress, improper care, or natural shedding. Causes: 1. Environmental stress: Sudden changes in temperature, light, or humidity can cause leaf drop. 2. Improper care: Inadequate watering or nutrient deficiencies can lead to stress and leaf shedding. 3. Natural shedding: Some cuttings may naturally shed leaves during the rooting process. Solutions: Stable environment: Maintain stable environmental conditions to prevent sudden changes in temperature, light, or humidity. Proper care: Provide appropriate watering and balanced fertilization to minimize stress. Accept natural leaf drop: Some leaf drop may be natural, and the cuttings can still root successfully. Monitor and adjust: Regularly inspect the cuttings for any signs of leaf drop and adjust care accordingly.
