When we moved in our new place in Feb., we noticed this grass/weed everywhere. How do you get rid of it? Can you get of it?

I believe that there is a rule of thumb that if your lawn is over 50%-60% weeds, the recommended course of action is to kill off the whole lawn and start over. Fall is the perfect time to do that! If your lawn is less than 50% weeds, applying weed n' feed that you can get at any home depot or Lowe's works to eliminate most weeds, and overseeding grass seed a month or so after that to fill in bare spots. I am not familiar with nutgrass. From its name, I'm assuming that it is a grassey weed, so weed n' feed would probably not work to kill it too well. However, if it is like crabgrass, it will die in the fall, and weed n' feed will work to prevent new nutgrass seeds (and all seeds) from germinating if you apply it in the spring. There may be products available at your local hd or lowe's or other local nursery that are made to deal specifically with nutgrass. If your lawn isn't too big, and the nutgrass not too extensive, you could also try good ol' fashioned weed pulling. So, first decide whether or not there is enough actual grass to make it worth it to try to save your current lawn. If there is, any weed n' feed product will certainly do some good in restoring your lawn. Fertilizing your lawn a couple of times a year is a good idea anyway to keep your grass healthy, even if you didn't have a weed problem. Hope this helps.

Nutgrass is also called nutsedge, and the best you can hope for is to control the above-ground portions of this weed. There are several products marketed for this; one is called Sedgehammer, but you can google to find others, or ask your local lawn supply company or extension agent.

The problem with nutsedge is that its underground reproductive system is a system of little nutlets that are pretty deep in the soil. You can keep spraying it to kill the topgrowth, but the nutlets will not die. I have been told by knowledgable turf people that if you persist in killing off the topgrowth for a number of years, you may 'frustrate' the plant to death, but that takes time.

One thing I know for sure -- DO NOT PULL IT. Pulling nutsedge only encourages the underground nutlets to generate new growth, which makes your problem worse.

We have a lot of here in Kansas, too, and last summer we had a bumper crop of it, so I sympathize!

I just read on the WWW that PREEN for grass and weeds claims to be able to kill nutgrass.

I live in Mason Ohio and am reducing the impact nutgrass has had to my yard. This area is getting overgrown with nutgrass, the golf courses have it, my neighbors have it. It feels like I am the only anal one who wants to destroy it.

I lost about 1/20 of my front yard a couple years ago to nutgrass, just came up nobody knew about it. Each year I have gotton "smarter" reducing the impact to my yard.

This year, I have able to identify the early light green stages of the weed.

My current plan of attack to rake out the spots with a 4 prong rake and spray use Ortho crabgrass killer (list nutgrass).


Any ideas to improve / reduce the weed.
