Treating Hibiscus with White Spots and Flying Insects

Neem Oil Spray for Hibiscus Pests and Disease

Mary's hibiscus has white spots on leaves and buds that turn into flies, plus yellowing, dropping leaves. She used Ortho spray without success.

Recommended Treatment

Use a neem oil-based 3-in-1 spray (e.g., Garden Safe) that acts as insecticide, fungicide, and miticide. This single product addresses the likely complex of pests (whiteflies, aphids) and possible fungal spots. Apply thoroughly to all surfaces, including leaf undersides, following label directions. Repeat as directed. If no improvement in 2–3 weeks, seek further diagnosis.
