Pests

Pests such as mealybugs, spider mites, and scale insects can also cause yellowing in succulents. These pests feed on the sap of the plant, causing the leaves to turn yellow or brown.

To get rid of pests, use an insecticidal soap or neem oil. Apply the treatment directly to the affected areas and repeat every week until the pests are gone.

Fertilizer

While succulents don't require fertilization, they can benefit from it. However, using the wrong type of fertilizer or applying too much can cause yellowing.

Root Rot

Root rot is a serious issue that occurs when the roots of a succulent are damaged by overwatering. The roots begin to rot, which prevents them from absorbing water and nutrients properly.

To fix root rot, remove the succulent from its pot and inspect the roots. Remove any rotten or dead roots with a clean pair of scissors or pruning shears. Repot the succulent into fresh soil and let it dry out completely before watering again.

To prevent fungal infections, make sure to provide adequate air circulation and avoid overwatering your succulents. If you do notice signs of a fungal infection, use a fungicide to treat the affected areas.
