Why does your Calathea makoyana have white powder? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyA fungal disease that thrives in high humidity with poor air circulation, common in Calathea. It manifests as white, flour-like spots on the surface of the leaves.
These small, sap-sucking insects produce a white, cottony waxy secretion to protect themselves. They often congregate at the leaf nodes and junctions of the Peacock Plant.
Calathea makoyana is sensitive to chemicals in tap water. As water evaporates from the leaf surface, calcium and magnesium salts can leave a white, crusty film.
While mites themselves aren't white, their webbing can look like a fine white dust or powder across the foliage. They thrive in dry environments which is detrimental to this tropical plant.
