Black Spots on Aloe Plants

Overwatering

• Despite their lush green leaves, aloe plants are from the desert, where the rainfall is very low. Black spots can be a sign of overwatering or of mold due to overwatering. Only water aloe plants when the soil feels dry to the touch.

Aloe Rust

• Aloe rust is a fungal disease that causes both black and brown spots on the leaves. To avoid this disease, do not let water stay on the leaves.

Solution

• When you see black spots on the aloe, reduce watering immediately. If that does not solve the problem, you may choose to pinch off the affected leaves or to take a cutting and start over from scratch.
