Description: Yellowing of leaves in Plumeria cuttings can be caused by nutrient deficiencies and improper light conditions. Causes: 1. Nutrient deficiencies: Inadequate or imbalanced nutrient supply can lead to yellowing leaves. 2. Improper light conditions: Plumeria cuttings require adequate sunlight, but excessive direct sunlight can scorch the leaves, leading to yellowing. Solutions: Balanced fertilization: Provide a balanced and appropriate fertilizer to ensure the cuttings receive essential nutrients for healthy growth. Adjust light exposure: Place the cuttings in a location with bright, indirect sunlight to avoid leaf burn while promoting healthy growth. Monitor and care: Regularly check the leaves for any signs of yellowing or nutrient deficiencies, and adjust care accordingly.
