Mealybugs are also pests of desert roses. They usually appear as small, white, cottony spots on leaves and stems.

This rot occurs in the swollen stems and main stems of desert roses. This causes the leaves to turn yellow, but not always fall off.
Before you throw the plant away, see if it heals itself. Larger desert roses can sometimes survive this type of rot.
