Fiddle leaf fig plants are a popular choice for indoor plants due to their large, attractive leaves. However, they are prone to fungal infections, which can lead to yellowing or black spots on the leaves and even death if left untreated. In this article, we will discuss various ways to get rid of fungus on fiddle leaf plants.

Identify the Fungal Infection

Before you start treating the fungus, it’s essential to identify whether your fiddle leaf plant has a fungal infection. The common signs of fungal infection in fiddle leaf plants include:

  • Yellowing or black spots on the leaves
  • Stunted growth
  • Wilting leaves
  • Powdery substance on the leaves

If you notice any of these signs, it’s crucial to act fast to prevent the fungus from spreading.

Remove Infected Leaves

The first step in treating a fungal infection in your fiddle leaf plant is to remove all infected leaves. Use sterile pruning shears or scissors to cut off any leaves that have large patches of fungus. Make sure you cut the entire leaf and not just the affected part, as this could spread the fungus further.

Improve Air Circulation

Fungal infections thrive in moist environments with poor air circulation. To prevent the fungus from spreading, make sure your fiddle leaf plant is placed in an area with good air circulation. You can also use a fan to improve air movement around the plant.

Reduce Humidity

High humidity levels can also encourage fungal growth. To reduce humidity levels around your fiddle leaf plant, avoid overwatering and misting the leaves. You can also use a dehumidifier in the room to keep humidity levels low.

Use Fungicides

If removing infected leaves and improving air circulation and humidity levels doesn’t work, you may need to use fungicides to treat the fungus. There are several fungicides available in the market specifically formulated for fiddle leaf plants. Follow the instructions carefully when applying the fungicide, and make sure you wear protective gear such as gloves and a mask to avoid inhaling the chemicals.

Repot the Plant

If your fiddle leaf plant is severely infected with fungus, it may be time to repot the plant. Fungal spores can remain in the soil, leading to recurring fungal infections. Repotting the plant in fresh, sterile soil can help prevent future fungal infections.
