My normally immaculately green lawn has taken a bad turn. I have several blotches of completely brown grass (pics below). I water regularly, probably overwater if anything. A couple weeks ago I applied some Scotts Turf Builder plus Weed Control. I had previously applied the same weed control about 2 months ago. I think it says do it only twice per year, so maybe that's where I messed up? A couple days after application, I think my entire lawn had a slightly brownish look but it only lasted one day (except for the bad spots in the back) after I gave it a good watering....now some of my lawn is great, some far from great. Anyways, what do I do now? I've been watering the dry spots extra, but they don't seem to be making much progress after a week. I have a sinking feeling that it will not come back. Any ideas? Thanks!
