Why does your Pachyphytum compactum have white cottony spots? Diagnose the cause and fix it with our step-by-step guide.
Mealybugs are common pests for succulents like Pachyphytum compactum that secrete a white, waxy, cotton-like substance to protect themselves. They feed on the plant's sap, often clustering in the crevices between the fleshy leaves.
This fungal disease manifests as white, flour-like patches on the surface of the leaves, often appearing in humid conditions. While less common in succulents than in leafy plants, low airflow around the compact leaves can trigger it.
Certain types of scale can produce small, white, cottony accumulations as they grow and produce wax. These pests attach themselves to the stem or leaf base of the Moonstone, making them hard to spot initially.
