Powdery Mildew

This fungal disease is very common in Camellia species when humidity is high and air circulation is poor. It manifests as white, flour-like patches on the surface of leaves, which can eventually cause leaf curling and premature drop.

Mealybug Infestation

Mealybugs are small, soft-bodied insects that secrete a white, waxy, cottony substance to protect themselves. They congregate on the undersides of Camellia leaves and near new buds, sucking sap and weakening the plant.

Common

How to confirm: Inspect the leaf axils (where the leaf meets the stem) for tiny, moving white clusters that feel slightly sticky.

Scale Insects (Cottony Scale)

Certain species of scale insects produce a white, powdery or waxy coating as they colonize the stems and leaves of Camellia plants. This can lead to stunted growth and the production of honeydew, which may attract sooty mold.

Common
