Identification

Cottony white spots on top of dense orange leaves = powdery mildew (uncommon on citrus but possible in dry, 72°F conditions).

Pure Neem Oil (Dyna-Gro) – organic, fungicide, miticide, rain-fast. Alters leaf taste so pests leave.
Apply per label; cover both leaf surfaces.

Neem is a broad-spectrum, low-toxicity option.
