Better known as Yellow Nut sedge. Oh, it's a pain to get out. I wanted to throw out my 2 cents on my experiences so far with nut grass. In my backyard I have a really bad nut grass problem. I asked some friends on Facebook what they suggest. The best advice I got was once the nut grass is up if it before June 21st, spray it with Sedgehammer Herbicide. If it is after June 21st, use Dismiss Herbicide. For me when I decided to treat the nut grass it was after June 21st, so I chose Dismiss. At the top of the page is what my backyard looked like before. In the pictures below you can see how well Dismiss worked. Now, I still have to wait until next year to see my results. I am hopeful that it took out most of the nut grass, but we'll see. I also posted pictures of both Sedgehammer and Dismiss below. You can buy either one on Ebay. DO NOT SPRAY EITHER CHEMICAL ON THE DAYLILY FOLIAGE.
This was after my first treatment of Dismiss.
You can see most of the nut grass started to yellow the first week.
This picture above was taken in October at the end of the season. Hoping the nut grass does not come back. We will see this coming May.
