Sedgehammer Plus Turf Herbicide - 4 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

I have been dealing with a nutsedge problem in my lawn for years. Nothing seemed to work so I thought I’d give this product a try. Very reasonably priced so I figured nothing to lose. Sprayed the sedgehammer a week ago and left for vacation. Came back yesterday and every blade of nutsedge was gone! Very impressed!! I just wish I had taken before pics..

I have used this product in the past and I will admit it lasts me about 2 years between applications before I see the grass come up again. I've tried over the counter stuff to no avail and I had a landscaper fill me up a sprayer for free. Said give it a few weeks and that's about what it takes. You forget about it really and then you look and see oh there is no more of that nutsedge. I buy the one application because that's all I've ever needed. I have this crap coming up ever couple of years and this does the job. Eventually they find a way but it's at least a couple years before I see it again. Buy this if you want to get rid of that nutsedge grass and not have to worry about it for a long time. Dont have to worry about chemical storage and effectiveness this one application. Covers a lot of area. When something works you stick with it and this stuff works and granted not super cheap but also not really expensive considering a spray bottle of hose end crap is $10 and that doesn't work except feed the weeds.

I've been using this product for 2 years, and it does exactly what it claims.I had a really bad infestation. Almost a 1/3 of my lawn was covered in sedge back in 2010. I had no idea what it was. I was pulling it out, which just made it worse. I discovered Sedgehammer in 2011. This saved my lawn.The price has dropped since then, but I noticed they raised the shipping cost. It should not cost $10 to ship such a small package in the mail. I do not like sellers that do this.There are a few things you must do for success.1. Wait to apply the product 3 days after you mow the lawn. This gives the sedge leaves a chance to grown.2. Make sure it will not rain for at least 4 hours. My first time using the product, it rained after 3 hours, and the product still did the job.3. Mix as directed. Do not add any other chemicals to mix. I have tested this product mixed in a 1 gallon and 2 gallon water solution, and I achieved the same results. 2 gallons of water allowed me to cover a wider area.4. Spray on the sedge plant leaves. no need to apply to the ground. The chemicals are absorbed into the leaf, and will make it's way down to the nut, and kill the plant, root and nut.5. The plant takes a while to die. You may not see anything for 7 days. Eventually you will see the plant die.NEVER PULL THE PLANT OUT OF THE GROUND. This will turn one plant into 5 or more, because the nuts will stay in the ground, and sprout their own new plant.6. Do not mow lawn for at least 3 to 4 days.7. Mow the lawn. You will notice the sedge will not outgrow the grass. This is how you know it's working.I recommend buying enough for a second application. There may be nuts that did not sprout during the first application, and will pop up a few weeks later.

Takes a few weeks to work as stated. Very happy with the results. Every year we have had a tremendous amount of nutsedge. Not now! Follow the instructions for the best time to apply. Be sure to not store the mixed product as noted in the instructions. It is not effective if stored mixed. From all the choices out there, this one appeared to be the safest for other grass and the most effective.

Perfect product. One application killed all nut grass and they don't come back

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

For those that say it didn't do anything, be patient! It takes about a week. This photo is my nutsedge a week after spraying. Works well!! Will buy again for another small patch growing in the back yard.
