ok, grass is comming up, roots and all. everything was fine, till last week, when the hottest weather hit. i have two lawns, browning bad, and grass comes right out, roots and all. grubs u say? no way. i put so much crap on this lawn, im surprised the people are still living. what could it be? one was what i belived to be a fungus, hit it with bayleton, it stopped spreading, but the damaged areas are commin out in my hand. the other, the customer had a fence put in, and the fence man hammered the sprinkler pipes, but they never realized it. i thought heat stressed lawns just turned brown? this one is comming up like a carpet. there are no grubs present at either property.
