Mealybugs

Mealybugs are small, soft-bodied insects that secrete a white, waxy, cottony substance to protect themselves. They congregate in the crevices of Lily Bright Joy leaves and flower buds, sucking sap and weakening the plant.

Very Common

Cottony Blotch (Fungal/Oomycete)

Certain fungal pathogens can manifest as white, fuzzy patches on the foliage of Lilies. This is often triggered by high humidity and poor air circulation around the dense leaves of the Bright Joy variety.

Common

Scale Insects (Cottony Scale)

Some species of scale insects produce a white, cottony appearance as they mature. They attach themselves firmly to the stems and leaves of the Lily, causing localized discoloration.

Common
