Leaf Drop

Underwatering

To address leaf drop caused by underwatering, it's crucial to establish a consistent watering schedule. Rubber trees prefer their soil to be kept lightly moist. Allow the top inch of soil to dry out before watering again. In dry environments, consider increasing humidity around the plant by placing a humidifier nearby or setting the pot on a tray filled with pebbles and water. Adjust your watering frequency with seasonal changes, as plants may require less water in the winter.

Spider Mite Infestation

Spider mites are tiny pests that thrive in warm, dry conditions. They feed on the sap of rubber tree plants, causing yellowing, speckled leaves, and overall plant stress.

To combat spider mites, first isolate the affected plant to prevent spread. Increase humidity around the plant, as spider mites prefer dry conditions. Wash the plant with a strong stream of water to physically remove the pests. For severe infestations, apply neem oil or insecticidal soap directly to the leaves, ensuring to cover both sides. Repeat the treatment every 7-10 days until the infestation is under control. Regularly inspect the plant and maintain proper care to prevent re-infestation.

Powdery Mildew

Fungal infection

Powdery mildew is a fungal disease that appears as white, powdery spots on the leaves and stems of rubber trees. To manage this issue, increase air circulation around your plant and reduce humidity levels if they are excessively high. Infected leaves should be removed and destroyed to prevent the spread of the fungus. For severe infections, apply a fungicide specifically designed to combat powdery mildew, following the manufacturer's instructions carefully. Ensure the plant is not overcrowded and receives adequate light.
