Why does your Anthurium andraeanum Mont Blanc have white cottony spots? Diagnose the cause and fix it with our step-by-step guide.
These small insects secrete a waxy, white substance that looks like cottony tufts to protect themselves. They congregate in the leaf axils and undersides of the Anthurium leaves, sucking sap and weakening the plant.
This fungal disease manifests as white, flour-like patches on the leaf surfaces, often appearing when humidity is high but air circulation is poor. It can cause the leaves of Anthuriums to become distorted or necrotic.
Certain soft rot pathogens can create localized areas of white, water-soaked tissue that eventually look fuzzy as the plant tissue breaks down. This is common in Anthuriums kept in overly damp, stagnant environments.
