SEDGEHAMMERPlus Turf Herbicide - 2 Pack of 13.5 Gram Pack of USA-Made Purple & Yellow Nutsedge Killer for Lawns with Pre-Mixed Surfactant - Lawn & Pet Safe Weed Killer Mix for Residential Use

We have the worse problem with nutsedge and this works! It kills it and we reply 6 weeks later no issues. Doesn’t hurt my other plants either.

I have been using this product for years. Used regularly, it will get rid of the sedge in your yard. Guaranteed!

Used as instructions direct, Sedgehammer killed the target weeds without damaging or even stressing my St Augustine grass. The instructions could be a little clearer for application to small areas, but that aside, this product was easy to use, effective and although pricey, it is economical when you consider floundering around trying a variety of products that don’t work.

This stuff works great. Just follow the instructions and be patient.

I have tried alot of products to try and control sedge in my St. Augustine grass here in Florida. None worked. Took a chance with Sedgehammer. I don't understand some of the negative comments from nay sayers. I applied the product with a pump sprayer. Perhaps I used more than I should in the sedge areas of my lawn. The product also was applied with no rain or watering for 4 days....although not mandated by instructions. There were no visible signs the product was working on the sedge. Several days later I mowed the grass. To my happy surprise, once mowed, as of this writing, the sedge has not grown back. It's gone in all areas where I sprayed. Obviously, Sedgehammer gets down to the roots and destroys the weed. Thank you Sedgehammer. Perhaps it's best called Sedgekiller!

Bought two packs, and were not nearly enough for a large yard infested with nutsedge. So I used leftover Ortho product to cover the remaining parts. My biggest reservation about this product is that it requires a lot of patience to see visible results. It is very difficult to see any progress in 2-4 days. By day 6 some leaves turned color just a little, but not convincingly. It took about 9-10 days for the leaves to mostly yellow to demonstrate it was working. In contrast, the Ortho product, which you can sourced locally at HD, shows visible results in one day. By day 3, it is very clear they are dying. By day 9-10, most of the nutsedge have long died and the leaves are, brown, dead and diminished, whereas those treated with Sedgehammer+ are fully yellow but not decayed. Time will tell which product works better at killing the root system, but I will surely report back if there is a big recurrence. (See update at bottom)I'd suggest the Ortho type that hooks up to the garden hose is the best bet if you have a large yard and a large infestation, because in practice it is a lot easier and faster to sweep the lawn than with the Sedgehammer dispensed with a canister, despite the inconvenience of dragging the hose around. With the Sedgehammer+, I found myself looking moving slowly to look very carefully at the ground to spot the nutsedge, and when young it is not always easy to identify them in the bermuda. Also, the Ortho will give rapid feedback if you are impatient. Last year I did not bother finishing off the nutsedge, so naturally it returned this Spring with a vengeance. I also bought the Bonide product this month, so I may be applying that to missed areas to see how that works. With a small yard and small infestation, I would trust the other reviews about effectiveness and use this.With either product, I don't believe either failed to work on areas that were sprayed adequately. I believe both products state that the leaves should be glistening upon application, so I was careful to do that. Both have killed large areas of nutsedge, which is quite satisfying. But as I said, the long term results will be interesting.Update:The Ortho areas have much higher regrowth of nutsedge than the areas treated with Sedgehammer. Currently evaluating the Bonide product for comparison, which is as fast acting as the Ortho. After a few weeks and mowing, it is obvious that much of the Ortho treated areas require a vast re-treatment, although at this stage the lawn does look much better than in its original condition. However, I did discover a handful of new growths in the Sedgehammer treated areas, but the results are still very satisfactory. For incidental spot treatments after the fact, it is more convenient to have a hand spray bottle of Ortho around than to mix up a batch of whatever. Whatever the product, it is clear that every treated area needs to be re-walked every few days for a number of weeks or months and treated as needed until the nutsedge root system is finished off. A big problem with a large infestation is that it is extremely time consuming to treat areas with a hand pump sprayer because you need to move very slowly and methodically to spray every single nutsedge. The other day it took me a couple of hours to walk the lawn and spray every one I could find, and I used 2/3 of a bottle of Bonide, which covers about 2000 sq ft. Two days later, I found a few missed spots (often requiring me to bend over to carefully peer into the bermuda) and applied Ortho by hand.Depending on how well the Bonide works, I may be buying more Sedgehammer to finish the job once that bottle is exhausted. Performance aside, the main difference between Bonide and Sedgehammer is cost, because I believe I can treat an area about 3X as large using Bonide than Sedgehammer. Bonide also deals with crabgrass and many other weeds, so it is a more versatile product with more uses than just nutsedge. Unlike the Sedgehammer, the Bonide can stress the bermuda, so yellow spotting is a temporary side effect.The most important advice is to identify the problem early and tackle it aggressively and frequently before it blossoms into a widespread problem. Second, some time after treatments, if you get on your hands and knees, you will invariably find small and fine nutsedge that there is no way you can see from a standing height. No wonder why this is such a difficult weed. Every time I walk the lawn thinking there is just a handful to deal with, it almost always winds up turning into a bigger problem than anticipated. Those of you with small lawns should have a much more manageable problem.Update 2: There are some spots in the yard in which nutsedge have almost eliminated. I say "some" and "almost" because invariably I can walk the lawn over a couple months after waging the war and still find what I believe are new growth, as well as some lurking under the mowing height. From a glance though, the whole yard looks much better, but the problem simply has yet to be eliminated and will come back with a vengeance next year if not finished off. Last month there was about a two week period where I would systematically inspect and re-treat portions of the lawn every day or two before I applied four packs of Sedgehammer and went into a long wait and see mode. So far this year, I've used about 5 large spray bottles of Ortho, a dozen hand spray bottles of Ortho, four bottles of Bonide, and six packs of Sedgehammer.As a tip, I purchased a separate listing of Sedgehammer containing a six pack for a much better unit price than this single listing. May even purchase another soon.Aug 2 update: After a couple months of hot dry weather, last week we had 3 inches of rain which breathed new life into the nutsedge. Every single area of the lawn has resurged with that new moisture, including areas treated with Sedgehammer. And I mean every and all the usual suspect areas. It could be that because I had a longer term infestation, it is unreasonable to expect any product to quickly do the job. I went through my last pack of this and bought some more Bonide. The reasoning is that it is just not possible to determine for a couple of weeks whether you missed a spot or not with this, plus it is a post-emergent killer of other weeds. Meanwhile, while awaiting results of this, you are letting new and missed nutsedge mature. If you have a very mature and established turf, if you've read this whole review, you'll know that there is no way you can possibly see every single blade of nutsedge in your bermuda on one pass. Hopefully, by getting these new sprouts while relatively young, I wonder if I can get the better of this, since I was too late this Spring. I'm not sure what conditions those who claim that this works so well are dealing with

Woks on nut grass just takes a couple of weeks, I retreated specific area 1 time very week

Only thing I have ever used that will kill nutsedge.
