Fiddle leaf fig plants, also known as Ficus lyrata, are popular houseplants that have gained a lot of attention in recent years. These plants feature large, violin-shaped leaves that add a touch of elegance to any room. However, as with any plant, fiddle leaf figs can encounter some issues that can cause concern for plant owners. One such issue is the presence of brown spots on the leaves. In this article, we’ll explore the cause of brown spots on fiddle leaf fig plants and discuss ways to prevent and treat this issue.

What Causes Brown Spots on Fiddle Leaf Fig Plants?

Brown spots on fiddle leaf fig plants can be caused by a variety of factors. Here are some of the most common reasons:

1. Overwatering

One of the most common reasons for brown spots on fiddle leaf fig plants is overwatering. When the soil is constantly wet, it can lead to root rot, which can cause brown spots on the leaves. Additionally, overwatering can cause the plant to become susceptible to fungal infections, which can also cause brown spots.

2. Underwatering

On the other hand, underwatering can also cause brown spots on fiddle leaf fig plants. When the plant doesn’t receive enough water, it will start to dry out, which can lead to brown spots and crispy leaves.

3. Low Humidity

Fiddle leaf fig plants are native to tropical regions, where they thrive in high humidity environments. When grown indoors, they may not receive enough humidity, which can cause brown spots on the leaves.

4. Too Much Sunlight

While fiddle leaf fig plants require bright indirect sunlight to grow, too much direct sunlight can cause brown spots and sunburn on the leaves.

5. Pests

Finally, brown spots on fiddle leaf fig plants can be caused by pests such as spider mites and mealybugs. These pests can damage the leaves and cause brown spots to appear.

  • Water your plant only when the top inch of soil is dry
