Hello, I am a really new lawncare trainee and don't know much. I have gotten a lot of help here reading other threads and I really appreciate it. A lot of the little I know came from here I have St. Augustine with a lot of Bahia (I think) mixed in. There seems to be almost as much Bahia as St. Augustine. My problem is in trying to find a chemical to get rid of the Bahia. I don't know if it can even be done. Can it? If so, how do I select a product when they say that you can, or you CANNOT use on floratam. How can I tell Floratam from regular St. Augustine grass? I have found this warning about floratam on fertilizer and other chemicals. I am afraid to try any kind of chemical on my lawn until I find out which type I have. I am going to insert an image, although it is rather fuzzy. I am in middle Georgia and it has been a very hot, dry summer. Hope someone can help.
