    Here's a couple pictures of it. I'm having trouble killing the light green grass off. Not sure what it is and what to put down to kill it. I am already putting down a crab grass preventer, 2 weed and feeds, and a winterizer every year. Tried spot spraying this with weedbgone but didn't have any luck.

    Yellow Nut sedge....
    sedge hammer works great
    or go to the big box store and they have a spray bottle of nutsedge killer ... works great!

    Awesome thanks! That was pretty painless, I'll pick up some of the herbicide. Out of curiosity though what is a sedge hammer or was that a misspelled sledge and you were making a joke?

    Sedge hammer is a chemical that will kill it too but it cost a little more. Just get the stuff at the big bkx store its in a green bottle. Dont pull the grass out it will break and multiply....

    This time of the year spray Sulfentrazone (dismiss), Sedgehammer will promote tillering while dieing late in the season. You can also tank mix sedgehammer and dismiss. Might cause yellow on turf stand but ultimate is to control spread of nutsedge.

    Can be weeded. They come up easy. Pulling them does not cause them to multiply. Nutsedge sends out a large rhizome/root network that will send up new plants.

    Just keep picking and eventually the rhizome's energy stores will be depleted and will not be able to grow new shoots, so the root system then dies off.

    I have seen a ton of it this year in Indiana. I have customers that have it. I really don't mind it gives me something to cut in this dry spell.

    Can not stop it by pulling, or digging em up. And it will be back next year even with chemical spraying. At least that is how nut grass works in our area.
