    This weed is popping up in many yards that I maintain. Its a grassy weed so that makes it even harder to control.

    Can anyone help with identifying it?

    I have this weed too. It is about 1/3 of the grass in one yard. I am looking for a way to get rid if it.

    its fescue clumps....its going to appear in most newly sodded lawns in new development. Its from erosion control....so really its not a weed, and will not die from regular broad-leaf pre and post emergent once its visible....

    Im not sure its fescue, becasue the first pic is a fecuse lawn with the weed in it. It could be a different types of fescue but I know I cant spray corsair or revolver on these lawns. If that is fescue I would most likely have to pull these weed by hand in my fescue lawn.

    Do we have any other opinions?

    You will get lots of different answers on this. If your photo was zoomed in a bit more, it might be easier to get an id.

    These situations can be difficult. You obviously have a Fescue lawn, so that makes it somewhat easier to start guessing. I can tell you for sure it is not any type of crabgrass.

    When seeding Fescue, there are often many types of unwanted grasses that are present in your seed mix.

    One of those is orchardgrass, however what you have does not appear to be that. It tends to spread out more in its growth pattern, and has a blue color. I've seen lots this lately, and yours does not have the same appearance.

    It could actually be a less desirable Fescue such as KY 31 in your mix.

    But if I had to bet, I would say Poa Trivialis. Poa Trivialis often contaminates Fescue seed mixes. It grows more vertical and much faster than your Fescue. It also has a lighter green color.

    If you cannot get a certain ID, take a sample to your local extension office.
