I need help with my lawn. I have patches of brown grass mixed in my yard. A knowledgeable person at the local farm supply store has told me it is bermuda grass. If this is the case it should green up, however these patches never really green up all year. This is not a new problem they have been like this for several years. This is an established yard, and I live in southwest Virginia. Here are some pictures, I have three large areas of this brown grass.
