Updated: February 18, 2023

Fiddle leaf fig plants are a popular choice for indoor decor due to their large, glossy leaves and elegant appearance. However, like any living thing, they are susceptible to diseases that can negatively impact their health and beauty. In this article, we will discuss some of the most common fiddly fig plant diseases, how to identify them, and the best ways to treat them.

Leaf Spot

Leaf spot is a common disease that affects many types of plants, including fiddle leaf figs. It is caused by a fungal infection that manifests as small brown or black spots on the leaves. These spots can grow larger over time and may cause the leaves to turn yellow and drop off.

To treat leaf spot, remove any infected leaves and dispose of them properly. Avoid getting water on the leaves when watering your plant, as this can promote fungal growth. You can also use a fungicidal spray to help prevent the disease from spreading.

Root Rot

Root rot is another common problem for fiddle leaf figs. It is caused by overwatering or poor drainage, which leads to an accumulation of moisture around the roots. Symptoms of root rot include yellowing leaves, wilting, and stunted growth.

To treat root rot, you will need to repot your plant in fresh soil with better drainage. Be sure to remove any affected roots before replanting. Avoid overwatering your plant in the future and make sure it has adequate drainage.

Anthracnose

Anthracnose is a fungal disease that can affect fiddle leaf figs as well as many other plants. It causes dark, sunken lesions on the leaves and stems and can lead to defoliation if left untreated.

To treat anthracnose, remove any infected plant parts and dispose of them properly. You can also use a fungicidal spray to help prevent the disease from spreading. Be sure to water your plant at the base to avoid getting water on the leaves, which can promote fungal growth.

Mealybugs

Mealybugs are small, white insects that can infest fiddle leaf fig plants. They feed on the sap of the plant and can cause yellowing leaves, stunted growth, and even death if left untreated.

To treat mealybugs, you can use a cotton swab dipped in rubbing alcohol to remove them from the leaves and stems. You can also use an insecticidal soap to help control the infestation. Be sure to inspect your plant regularly for signs of mealybugs and other pests.

Scale Insects

Scale insects are another common pest that can infest fiddle leaf figs. They are small, oval-shaped insects that attach themselves to the leaves and stems of the plant. They feed on the sap of the plant and can cause yellowing leaves, stunted growth, and even death if left untreated.

To treat scale insects, you can use a cotton swab dipped in rubbing alcohol to remove them from the leaves and stems. You can also use an insecticidal soap to help control the infestation. Be sure to inspect your plant regularly for signs of scale insects and other pests.
