Why does your Lilium Hybrid Termolie have white powder? Diagnose the cause and fix it with our step-by-step guide.
This fungal pathogen thrives in high humidity and moderate temperatures, common in Lily hybrids. It forms a distinct white, flour-like coating on the surface of the leaves, which can eventually lead to leaf yellowing and necrosis.
While typically associated with grey fuzzy mold, early stages or certain environmental conditions in Lilium can manifest as pale, whitish patches on petal edges and leaves before turning necrotic.
A heavy infestation of spider mites can cause 'stippling,' where tiny white or silver dots appear on the lily leaves due to cell damage. In severe cases, fine webbing may accompany these light-colored spots.
If you use overhead watering or foliar sprays with hard water, calcium or magnesium carbonates can dry on the leaf surface as a white, crusty residue.
