Q.Does Blue-eyed Grass Regrow In September After Drying Dead In August?
Our summer was so hot that the Blue-eyed grass all dried up and the dead blades were pulled out in August. I see what looks like about 2″ growth of grass. I am wondering if this is the blue-eyed grass or just weed grasses?

It probably won't bloom again till spring. The leaves gather energy that is stored in the rhizomes. Browned foliage can be cut back at the crown.
You may have some weed grasses filling in.
