My new tall fescue lawn has been taken over by brown patch. I purchased a scotts brand fungicide and treated my lawn 2 weeks ago, but I don't know what to do next? Should I retreat in a week or so with the same product? Or should I rake up all of the dead or dying grass and try to reseed those areas? Or just wait untill fall and aerate and reseed? My yard is a little over a year old. In Aprill it looked great, but then I think I made every mistake in the book. 1. I watered late when I got home from work! 2. I fertilized in the fall with scotts, then I re fertilized my new lawn in the spring with scotts. Too much nitrogen? 3. I I noticed that my grass had a few brown spots so I watered it every day when I could, and guess what? The spots increased!! 4. I have been using mulching blades and spreading throughout my yard. HELP!! Thanks for you help!
