What kind of grass is it. You are way up north so I figure it is a cool season grass. My grass is a mix of fescue, bluegrass, and Bermuda. The bermuda is done, and the fescue and bg would grow if we could get some rain. I did notice that the cool season grass on the north side of the house is getting some fungus on it. I might put some fungacide on it still just to help it get into the fall in a healthy state.
