Q.Graffiti mixed penta question
I love in South Florida. We are growing graffiti mixed pentas. They were very healthy but now the leaves are turning yellowish brown. Should i cut them back, it is getting cooler here?

You seem to be right on the edge of where these can survive in the ground outdoors. With this being said, it is best to treat these as an annual in your area. If they do come back, it will be a plus but is not guaranteed.
These are susceptible to some pests, and this can cause what you are seeing. Can you include photos? This will help me to rule this out. That old saying "A photo is worth a thousand words" could never be more true here.
