I had Zeon Zoysia grass put down in my back yard this past May. This was the grass that was recommended to us due to having more shade, and told it was more tolerate. I first had a drain system install due to bad draining that was killing my previous grass and taking away my soil. I then had the grass laid down. I cut the grass high and watered frequently. Everything was going fine while the weather was hot. Once the weather started to change, so did our grass. Right now it is thinning really bad and turning brown. I have worked really hard to maintain this grass and do not want to loss it. I have a sweeper, that I run over the grass to keep it clean of all excess grass clippings, leafs and pine straw. I live in Augusta, Georgia to give you an idea of our climate. Any tips or information you can give me to help save my grass would be much appreciated. I do not work any where near as hard on my Bermuda grass in my front yard!Thank you, Steve Lawver ( I can send pictures if this would help )

It could be that it has onctracted a fungal or bacterial infection. Especially if it is over-watered. This grass is quite tolerant of dry conditions. You can put down some wettable sulfur and dolomitic lime around the affected area, and this should help significantly.
