The Q&A Archives: White Edges On Hibiscus Leaves

Question: Some of the leaves' edges of our hibiscus are turning fuzzy white. We have no idea what that is or how to get rid of it. Do you have any sugguestion?

Answer: If the leaves have actually sprouted a fuzzy coating, you're probably dealing with powdery mildew, a fungal disease. You can pinch off the infected leaves to keep the disease from spreading, and to open the plant up to better air circulation. Powdery mildew can attack plants when daytime temperatures are warm, nighttime temperatures are cold, and humidity is high. Best wishes with your hibiscus!
