Mealybugs

These small, soft-bodied insects secrete a white, waxy, cotton-like substance to protect themselves. They congregate in the crevices of Lily Matrix leaves and stem nodes, sucking sap and weakening the plant.

Very Common

Botrytis Blight (Gray Mold)

This fungal pathogen thrives in high humidity and can manifest as fuzzy, white-to-gray patches on Lily flowers or foliage. It often enters through damaged tissue and can cause rapid decay of the lily's structure.

Powdery Mildew

A fungal disease that appears as a white, dusty coating on the surface of the leaves. Unlike mealybugs, this looks more like flour sprinkled on the plant and does not move.

Common

How to confirm: Rub the white spots with your finger; if it wipes off like dust rather than being a textured mass, it is likely mildew.

warning

Cottony Scale

Certain scale insect species produce a white, filamentous covering that resembles cotton. They attach firmly to the stem of the Lily Matrix and can lead to leaf yellowing.

Common
