Question From: l. osman - Fort Lauderdale, Florida, United States
Q: my hibiscus tree has many leaves with large white patches on them. Any idea what it could be? I don't see any bugs or other problems.
A: Sounds like fungus powdery mildew. Take a sample of the leaves to your local independent nursery for a positive Id. They will be able to recommend a fungicide. Best And Happy Yardening, Nancy
