Gardenia Bush Care

Question

Both of my gardenia bushes’ leaves are turning dark brown/black. What can I do to save them? Are they dying? I live in Orlando, FL with plenty of rain and humidity right now. Please advise.

Answer 1

This may be sooty mold. It happens when the plant gets a pest infestation. I would recommend using neem oil, as this will get rid of the sooty mold fungus and kill the pests. Here is some articles that will help you:
