Mealybugs

These small, soft-bodied insects secrete a white, waxy, cotton-like substance to protect themselves and the plant. They feed on the sap of Crassula species, often clustering in the crevices between leaves or near the stem nodes.

Very Common

Powdery Mildew

This fungal disease appears as a white, dusty coating on the surface of the leaves. In succulents like Crassula, it often occurs due to high humidity combined with poor air circulation around the foliage.

Common

How to confirm: Rub the white spots with your finger; if the residue wipes off easily like flour or dust, it is likely fungal.
