Mealybugs

These small insects secrete a white, waxy, cotton-like substance to protect themselves. In Graptopetalum, they often hide in the tight crevices between fleshy leaves and at the base of the rosette.

Very Common

Powdery Mildew

This fungal pathogen manifests as a white, dusty coating on the leaf surfaces. While more common in high humidity, it can affect succulents if air circulation is poor around the rosette.

Common

warning

Cottony Blight (Botrytis)
