Common Ficus Rubber Plant Diseases:
How to Identify and Treat

Updated: August 9, 2022

Ficus rubber plants are popular indoor plants that are loved for their attractive glossy leaves and easy care requirements. However, like any other plant, they are also prone to diseases that can cause discoloration, wilting, and even death. In this article, we will discuss some of the common ficus rubber plant diseases, how to identify them, and the most effective treatments.

Leaf Spot

Leaf spot is a fungal disease that affects the foliage of ficus rubber plants. It is characterized by small, dark spots on the leaves that gradually grow in size and turn yellow or brown. In severe cases, the leaves may fall off, causing defoliation. The disease thrives in humid conditions and can spread rapidly through contaminated soil or water.

Treatment

To treat leaf spot, remove and destroy all infected leaves to prevent the spread of the disease. Avoid overhead watering and keep the foliage dry as much as possible. Use a fungicide spray or systemic fungicide to control the disease. Repeat the treatment every two weeks until the symptoms disappear.

Root Rot

Root rot is a fungal disease that affects the roots of ficus rubber plants. It is caused by overwatering or poorly drained soil, which creates a favorable environment for fungi to thrive. The disease causes the roots to rot, leading to stunted growth, wilted leaves, and eventual death of the plant.

Treatment

To treat root rot, remove the plant from its pot and inspect the roots for any signs of rotting. Remove all affected roots with a sterile tool and repot the plant in fresh soil. Water the plant sparingly and avoid overwatering in the future. Use a fungicide treatment to prevent reinfection.

Mealybugs

Mealybugs are common pests that infest ficus rubber plants. They are small, soft-bodied insects that feed on the sap of the plant, causing yellowing, wilting, and stunted growth. Mealybugs also produce a waxy substance that covers their bodies, making them look like cotton balls.

Treatment

To treat mealybugs, use a cotton swab dipped in rubbing alcohol to remove the pests from the plant. Repeat the treatment every week until all the mealybugs are gone. You can also use insecticidal soap or neem oil to control the pests. Keep the plant in a well-ventilated area and avoid overfertilizing, as it can attract mealybugs.

Scale Insects

Scale insects are another common pest that infests ficus rubber plants. They are small, oval-shaped insects that attach themselves to the stems and leaves of the plant, sucking out the sap and causing yellowing, wilting, and discoloration. Scale insects also produce a sticky substance called honeydew that attracts ants and can lead to fungal growth.

Treatment

To treat scale insects, use a cotton swab dipped in rubbing alcohol to remove the pests from the plant. Repeat the treatment every week until all the scale insects are gone. You can also use insecticidal soap or neem oil to control the pests. Keep the plant in a well-ventilated area and avoid overfertilizing.
