    Help identify this stuff and figure out why this spot is destroyed.

    not sure why the third one wont load. There is a section of grass completely destroyed. Looks like it was sprayed with round up. If you took a rake to the grass it would take it down to dirt.

    Nutsedge.

    The grass surrounding doesn't look too bad though.

    If you've got smoked grass, then someone either sprayed sedgehammer (or equivalent) when the temps were too high and smoked the turf, or they tried round-up on it.

    I know about sedgehammer and high temps and the ill effects, done it.......

    I pulled it up last night and couldn't find a single grub. Checked green areas around it and it was well rooted as well.

    Third picture. Mysterious. It looks OK on the left side of the tree--like there is another property and a straight line between healthy and brown grass behind the square tree ring. How come? Better irrigation? Where are the nearest irrigation heads? Was this burned out a few weeks ago and now is partially recovered due to recent rains in our area? Is this tall fescue? Rye?

    It looks a bit dry in the foreground--wilted perhaps? Dig down--how dry or moist is it? Compare to nearby areas.

    How come the grass is green in a border around the stone mulch?

    Was this tree recently removed or a year or two old? What kind of tree? Killed by lightning?

    Are there any weeds in the stones? So did the owners spray a strong vegetation killer (like Ortho Triox) on the stones? Thereby killing the tree and injuring the grass?
