Why does your Anthurium andraeanum Joli have white cottony spots? Diagnose the cause and fix it with our step-by-step guide.
Mealybugs are small, soft-bodied insects that secrete a white, waxy, cottony substance to protect themselves. They congregate in the leaf axils and crevices of the Anthurium, sucking sap and causing yellowing or leaf drop.
While often appearing as hard bumps, certain scale species can produce white fungal growth or waxy exudates that look cottony. These pests attach to the stems and undersides of leaves, draining nutrients from the plant.
This fungal pathogen thrives in the high-humidity environments preferred by Anthuriums. It manifests as white, fuzzy mycelium spreading across leaf surfaces or stem bases, eventually leading to tissue rot.
