Appears to be fungus
I am trying not to give up on my lawn this season. I switched to organic lawn care two years ago. This year I have numerous browning of the grass blades. It happens right after it rains or when I water. I used to water my yard at night, since I have enough water pressure and its convenient for me. I water deeply for an inch every week or so. I mow properly, etc. After the grass gets wet, some places turn in to bluish green, then it turns into golden color and then to brown and i loose the grass. I live in upstate SC, where we have extreme drought condition. The grass is bermuda. I dont want to loose my lawn. Any help is greatly appreciated. Should I apply corn meal every month or so until it is controlled? What are your thoughts.
