Powdery Mildew

A fungal disease caused by high humidity and poor airflow around the lily foliage. It manifests as a white, flour-like coating on the surface of the leaves rather than distinct cottony clumps.

Common

Cottony Cushion Scale

These scale insects secrete a thick, white, waxy substance that looks like tufts of cotton on the lily's stalks. As they feed, they can excrete honeydew, which may lead to secondary black sooty mold growth.

Common
