Mealybugs

These small insects secrete a white, waxy, cotton-like substance to protect themselves. They congregate in the crevices of Echeveria leaves and at the base of the rosette, feeding on plant sap and weakening the succulent.

Very Common

How to confirm: Use a toothpick to gently probe the white spots; if they move or appear clustered in leaf axils, it is likely mealybugs.

Powdery Mildew

This fungal pathogen manifests as a white, dusty coating on the leaf surfaces. While more common in high-humidity environments, it can affect Echeveria if airflow is restricted around the rosette.

Common

How to confirm: Try wiping the white spots with a damp cloth; if the residue disappears easily and looks like dust rather than thick tufts, it is likely mildew.

2 Improve air circulation around the plant by spacing it away from other plants and ensuring a gentle breeze can reach the rosette.
3 Reduce humidity and avoid overhead watering, which can leave moisture trapped in the center of the rosette.
warning

Botrytis (Gray Mold)

In conditions of excessive moisture, Botrytis can cause white, fuzzy growth on decaying organic matter or wounded leaf tissue. It often targets the center of the Echeveria rosette if water remains trapped there.

Common

How to confirm: Check if the white spots are accompanied by soft, brownish, or mushy leaf tissue.
