Bought this product and Sedgehammer. We found the OrthoMax was more effective plus it's premixed and ready to go whereas with Sedgehammer you have to buy the dispenser and a "sticking agent" also and mix it in the dispenser (translation - hassle). The Ortho Max killed the nutsedge without killing the other (desirable) grass very effectively and it was easier to use. Oh and no, I'm not affiliated in any way with the manufacturer or seller, I just have a lawn obsessed hubby who hates Nutsedge and asked me to buy several types of product and he also hired a professional service to address the problem.

Of all the options, we were most skeptical of the OrthoMax working, but it worked the best, fastest and cheapest and didn't do damage to our lawn; whereas the professional service killed the nutsedge AND the entire lawn...months later we still have an enormous brown patch where the professional treated...nothing but nothing is growing there (no weeds - yey! no grass, not one blade survived - boo!). They treated the back yard, we treated the front so it was a clear comparison.

The areas sprayed with the Ortho Max, the nutsedge hasn't returned.

The areas with the Sedgehammer, the nutsedge returned with a vengeance.

The entire area treated by the professional is brown. At least in the front yard, we still have a lawn!

We have truly tried a variety of methods to kill the nutsedge and have a clear understanding of what did and didn't work. Ortho Max works. We bought more from Amazon (only place I've found it) and treated the other side of our front yard with the same results..I am confident this product works the best of everything we tried.

I bought this product to kill or control nutsedge in a decorative garden in Minnesota. I had tried the usual products with no success. Even glyphosate (generic Roundup) didn't work. The Ortho Nutsedge Killer wasn't available locally, so I ordered two bottles. This one works! The nutsedge started to yellow and droop 2-3 days after application. Weeds dead in 5-7 days. Be careful applying. Get close to the weed and don't allow any over-spray. This product will kill off any decorative plants. Follow the instructions on the label.

We landscaped our front yard in 2009, a few months after moving into our newly constructed home, and ordered a full dump truck load of topsoil from a local landscaper to build up our natural areas. It must have been full of nutsedge because the grassy weeds not only started appearing shortly thereafter, but they multipled like wildfire, and 3 years later I'm still struggling to get rid of the crazy infestation. I've tried Round Up, which seemed to work at first, turning the grassy blades yellow, then brown. But it didn't kill the numerous tubers at the root, and within a few weeks there were more weeds coming up than I originally killed. I've tried pulling, but that obviously didn't work either, because for every weed I pulled out, there were 2 to 3 tubers still left underground that broke off of the main plant when I pulled it up.

I hate using chemicals of any kind to treat weeds. I'm more of a pull them up as I see them kind of person. But I was at my wit's end until I found this little green bottle. Yes, it's expensive for the small quantity that you get, but it works. I originally ordered 4 bottles, which covered about 90% of the weeds, and then had to order another 4 for a second treatment. But at this point, $80 seems cheap for the results! Two weeks after the first treatment, most of the nutsedge has turned brown and is dying. I just came in from spraying a second treatment, and made sure to cover all new sprouts that have appeared since the first one. My ornamental grasses, shrubs, and trees didn't seem to be affected at all by the overspray.

My front lawn used to be a pretty healthy hybrid bermuda. A few years ago some nutgrass got into it, and spread (not quite like wildfire - maybe because we were in a drought). We did battle using the usual weapons - Montery Weed Hoe, Manage, Sedgehammer. all of them needed some significant prep. This year was a banner year for spring rain, and while bermuda prefers dry weather, nutgrass THRIVES in wet soil. This summer I had more nutgrass than bermud! all was lost. A friend suggested this product, and i resisted. until he bought me a bottle "because it's really cheap" Now I really had my doubts. As an experiment, i sprayed a 4-foot by 8-foot area of lawn, in the area most choked by the nutgrass. After three weeks. the gardener observed that I had a rectangle of bermuda in the middle of a sea of nutgrass. The rest of the lawn got the treatment last weekend, hope our hot weather holds out. Man, this stuff works.
I agree with some reviewers, in that it should come in a larger container, but i used it sparingly and maybe a little less thoroughly than the label says, but i can't be happier with the results. it is the most effective nutgrass killer i've ever used, and it costs 1 tenth what the others did.
