So I have this new all season account, typical cool season blend of grass in the front.Now in the back 50% is cool season ,then there's a straight horizontal seam if you will, where the other 50% of grass butts up to it.I have no idea what kind of turf that is, its a bit of a nightmare to work with.It lays flat, if you cut it too short I would imagine you'd see brown and stolons,air blowing the clumps turns it all raggedy,then going back over it with the mower puts it back into shape.Shes a nice lady & I think she would agree to Round up that mess in Sept.
