I've had Tall Fescue sod in for about 5 weeks now and it seems to be doing pretty good for Atlanta heat. I have had a couple of brown patches come out of no where and I've treated the grass with a fungicide about a week ago to see how it will do. However, I have noticed when cutting the grass that I've got some areas where it doesn't seem to be growing anywhere near as fast as other areas. It seems that the areas with the most shade grow faster that the areas that get more sun. Is that normal?
