I have this EVERY year. I am on the East Coast (transition area) and get this every year around late July/August. I killed my whole front lawn last year with Gly and overseeded. I did 3 split applications to make sure everything was dead-even the little bit of vinegrass which eventually died. The lawn came up excellent, and has been awesome all year up until now. I keep getting this!! I looks like a very fine lighter green grass (to me it's a W E E D) and comes in in patches all over the place!! Weed killers won't touch it because it must be a type of grass......? Please help me out.
