    Hi all- I've been struggling to properly ID a weed or some sort of grass that is growing in my yard. My yard is fescue and I live in KS. It really showed up last summer when we had a rainy period. It's a light green color and grows much quicker than my fescue. I've had a few companies come out and haven't got a proper ID from any of them, or any way to get rid of it. I use the various Scott's products for weed control, etc but it doesn't seem to phase it. I don't think it's goose or duck grass but I'm at a loss at what it is or how to get rid of it besides a non selective herbicide.

    Redo your photos: Go outside and dig up a small plant with roots, blades and seed head; then photograph it against a white cloth or piece of paper with the sun coming in from the side instead for overhead to get a view of the texture and get as close as possible without leaving out the roots to seed head. Then do some close up of the seed head.
    Yes, I'm a master photographer for a very long time.
    Re-submit them...but from even that it may look like poa anna or annual blue grass.
    We'll look closer

    Any tips to get rid of it besides round up? Unfortunately there are a lot of patches throughout the yard.

    Dig up patches and re-seed

    I was thinking the same thing. Never chimed in only because of house loose of a clump it is.

    But, regardles, a weedy grass is a weedy grass when treating. Either dig, or use roundup.

    I used roundup last fall on about a dozen fescue patches and one other unidentified grass. Just spot sprayed, and then re-seaded with a garden weasel.

    Had bad germination last fall during the late season drought. Some of it came up, but not as well as I liked.

    But, to my surprise, there is more in the patches than I expected that came back even after the hard winter. Though the patches are still visible, in about 4-6 weeks of optimal conditions and they'll fill in.

    What's the point? Patience is a virtue, and having a dead patch of grass for a total of 8 months isn't that big a deal.

    Also, I want to add that I've seen people pull it, and not get all the roots and it comes back, and I've seen people use round-up and not get it all. But I'd go with the roundup......

    K31 is a HUGE problem around here. Only mechanical removal or roundup treatment are options, and even that isn't fullproof as the stuff crops up in different places the following season.
    Even worse, quackgrass! Can one of the chemical companies PLEASE come up with a selective to take out quack?? And I am not talking about Certainty either, that stuff was near worthless on K31 and quackgrass.

    I've got one lawn (1860's farm house) that has nothing but quack grass in the entire lawn. When I first started working there, I couldn't figure out why I could barely get a spade to cut through the sod. Turns out it was the rhizomes from the quack grass. I have over 1000' of cut edges on that property and they are at least 6" deep so that try and stop the rhizomes from going into the landscape beds.

    Also starting to see quack grass pop up in newer sub-divisions. Obviously it's from the stripped off black dirt that was riddled with quack grass and then put back into the lawns after the houses were built.

    Worked on one lawn like this. Lots of quack grass. Only option was to smoke off the lawn and start over, but, the neighbors had it also, so over time it would eventually creep back in.
