I have several gardenia bushes. I live in the panhandle of Florida. My bushes were very green. After 2 weeks the leaves are all turning yellow and the good ones are starting to turn yellow. I applied a bug spray 2 weeks ago for all kinds of insects. What do I need to do to get the plants green again? I don't know if they are dying. This is the first year I had these types. I planted them last summer. Thank you so much.
