    I treat this lawn three times a year so I haven't been at the property for several months until yesterday and there is a ton of this crap in this lawn. I'm not sure what it's called. In the past I have handled very small patches on other properties by just digging it out.

    I don't cut the grass at that lawn, but I know from other lawns that I do cut that it's not the blades on the mower that cause that. I sharpen my blades every couple of days and it will still cut like that with this particular weed.

    It has nothing to do with sharp blades.

    I had this problem on a lawn last year. I am curious as to what type of grass it is. It only shows up this time of year and I have not found anything to control it.

    I think this has been posted in the past with no answers. I took it to a golf superintendent and he had no answer either.

    Can anybody help with this weed?

    I beleive it was there in the early spring, but it doesn't start to get fuzzy looking until later in the year. It just looked like some sort of undesireable field grass or something in the spring.

    Could you possibly get a closer image of the grass in the lawn; maybe, a foot or so from it and a close up of the roots and stem as well.

    Almost looks like goose grass.

    We had a turf field day last week. We saw something similar--the graduate student called it "fountain grass". It is an ornamental grass used for landscaping. It escapes due to the seed. Very fibrous--very tough to cut.

    Let it seed and I will know what it is.

    Gravely,
    It seems that since you don't maintain this lawn that its not your fault. It isn't the other guys fault either! The edges of properties and residential lawns are usually where the weeds are the toughest. Line trimmers always cut too low along the edge-tops and edging keeps the area open for seed germination. The other person is mulching apparently as the weed tops are sprangled as they are. That is how some of these types of weeds look when I mulch using my Exmark.
    It looks like either goose or dallis grass.... it is hard to tell without a seed stalk. Goose grass is determined by looking down on the weed base, as the base is shaped like a plus sign and is white colored. I can't describe the seed pods without looking at them.
    Try some MSMA or whatever you have for grassy weeds in your turf zone. When I treat commercials or residentials, I always give an extra stripe of pre or post along the street edge or sidewalks.
