Mealybugs

These small, soft-bodied insects secrete a white, waxy, cotton-like substance to protect themselves as they feed on the sap of the lily stem and leaves. They tend to cluster in the crevices between the Fedora lily's scales and leaf junctions.

Very Common

Powdery Mildew

This fungal pathogen manifests as white, flour-like patches on the surface of the foliage, which can eventually lead to yellowing and leaf drop. It thrives in high humidity and poor air circulation around the dense Fedora lily foliage.

Common

How to confirm: Check if the white spots can be rubbed off with your finger; if they appear as a fuzzy coating rather than distinct clumps, it is likely fungal.

Cottony Blotch (Botrytis cinerea)

While typically known for flower rot, Botrytis can cause grayish-white, fuzzy patches on the lily's foliage in damp conditions. It often starts as small necrotic spots that develop a moldy appearance.

Common
