Green Doc and the experts please chime in to this post. I don't know if I over did it with the FE apps on the Zoysia, but am going through serious issues now. Pictures to come at the end of the day. Spots in the Zoysia are starting to turn brown almost look just like it's died out. In the areas that are turning brown the blades are turning purple. The purple only appears in the areas that are brown but is spreading more and more now across the lawn.
