Fatsia is an evergreen shrub that belongs to the Araliaceae family. It’s a popular indoor plant because it’s easy to care for, and its large, glossy, and deeply lobed leaves add a tropical feel to any room. However, like any other plant, fatsia can be prone to problems. One of the most common issues with this plant is the appearance of brown spots on the leaves. In this article, we will explore the reasons behind these brown spots and how to prevent them.

Overwatering

One of the main reasons for brown spots on fatsia leaves is overwatering. Fatsia prefers moist soil but doesn’t like to sit in water. When the soil is too wet, the roots can’t get enough oxygen, leading to root rot. This condition causes brown spots on the leaves and can eventually kill the plant.

To prevent overwatering, make sure to let the soil dry out between watering. You can check if the soil is dry by sticking your finger about an inch into the soil. If it feels dry, it’s time to water your fatsia. Another way to prevent overwatering is by making sure your pot has proper drainage holes.

Underwatering

On the other hand, underwatering can also cause brown spots on fatsia leaves. When the plant doesn’t get enough water, it will start to wilt and develop brown spots on the leaves. To prevent this, make sure to water your fatsia regularly but don’t overdo it.

Pests

Another reason for brown spots on fatsia leaves is pests such as spider mites or mealybugs. These insects feed on the sap of the plant, causing brown spots and discoloration on the leaves. You can prevent pests by keeping your plant clean and free from debris. If you notice any pests, you can remove them by wiping the leaves with a damp cloth or using insecticidal soap.

Fungal Infections

Fungal infections can also cause brown spots on fatsia leaves. These infections occur when the plant is exposed to too much moisture, and the humidity levels are high. To prevent fungal infections, make sure to provide proper air circulation and avoid overcrowding your plant. If you notice any signs of fungal infection, such as brown spots or discoloration, remove the infected leaves and treat your plant with a fungicide.

Sunburn

Lastly, sunburn can also cause brown spots on fatsia leaves. When the plant is exposed to direct sunlight for extended periods, the leaves can become scorched and develop brown spots. To prevent sunburn, make sure to place your fatsia in a bright but indirect light location.
