I have a few spots in my lawn that even in these drought conditions have a tough time achieving a dry-out period every few days. Subsequently, the areas get diseased every year. I had always thought it was brownpatch, but I'm not so sure. This year I put down Heritage G on May 26, July 7, and July 30. This year the extreme heat and lack of rain has kept the moisture to a minimum until a few weeks ago. Now that the humidity has set in, the crap, whatever it is, is back. Can anyone identify what this is and how I can remedy this problem with out putting in drainage tile? Thanks.
