Customer Reviews for SedgeHammer Plus Herbicide

I've been fighting nutsedge for several years using nutsedge and crabgrass control products. They were disgustingly ineffective. I read of other people's experience with SedgeHammer on a daylily web page and decided to try it. Two days after spraying, the nutsedge started turning brown. Of equal importance, the daylilies surrounding it did not. They show no evidence of ever being near an herbicide. Am I satisfied? You bet!

This hot, dry summer we've been having here in Tidewater, Virginia has been awful for the fescue we grow here but perfect for nutsedge. My infestation was extensive. A few tips: Follow all the advice given in the instructions. Make sure the nutsedge has almost a week of growth on it; this is important. If the sedge is too small or you try to use it on a freshly cut lawn, the sedge won't have enough surface area to absorb sufficient herbicide to be effective. Also, make sure you sure use surfactent with the hebicide, it will help this very expensive chemical be absorbed more effectively by the sedge. Give the chemical time to work; the longer you can wait before mowing after application (I waited almost a week before mowing) the better the killoff. By that time (a week after application) I had an almost 95% killoff, the few live sedges were those few I had missed on the first application. One more application on the stragglers will finish the job.

I hate nut grass. It has been a problem for me from my first yard. I have used Roundup with an eye dropper and even a hypodermic syringe to kill the stuff. Then a man recommended SedgeHammer. The price was a little frightening but my resolve was firm. I bought it from DoMyOwnPestControl.com, received it promptly and used it with great success. The yellow nut grass began dying in 3 days and now is gone. I don't know if it will remain "gone", but I have enough of the stuff to "kill" it repeatedly.

Despite the fact that SedgeHammer is very expensive, I do not regret purchasing it because it WORKS! I bought the largest bottle which I think makes up to 40 gallons. So, I'll have enough to last me a few years. I recommend using an herbicide pump sprayer. I bought a Round-Up brand 2-gallon sprayer for $20 and it allows me to not waste as much SedgeHammer as I would if I used a watering can. I had A LOT of well-established sedge. About 7-10 days after the first application the sedge turned yellow and stopped growing and the grass was NOT harmed. I just did a second application because I had missed a lot sedge plants during the first application. This product is worth the $$.

I have been using this product for several years, and have found it to be the most effective for control of sedge, particularly in beds and around ornamentals in combination with Roundup. Because I am blessed with rich soil, everything grows well - sedge too; so control of sedge is an ongoing battle. The granular form of the product is convenient and easy to measure with the included measuring spoon.

I purchased SedgeHammer from DoMyOwnPestControl.com and it worked immediately. The process of getting my order filled and delivered was exceptional. I applied the product to the nutsedge that had taken over my front yard. After one application, no more nutsedge.

I have just under an acre and about 35-40% was infested with this nasty weed. I swear I'd be cutting my grass and when I would turn around to see how I was doing, the nutsedge was already an inch taller than the grass I just cut. I spent 5 hours on a Saturday covering my lawn with doubt. I cut my grass on Monday with despair not seeing any browning or "death". However, I sit here today with a big ol' grin on my face because it is evident that the weed isn't growing and my lawn is returning. It is truly amazing how this product does nothing to the grass and eliminates this pest of a weed. Best lawn purchase I've made in years.

SedgeHammer definitely worked on the yellow nutsedge that I applied it on. It is a little expensive, but the 1.33 oz. bottle is the way to go. A little bit goes a long way. I discussed my nutsedge problem with quite a few lawn pros and most agreed this is the most effective solution. I agree, and this product does kill the nutsedge, usually takes about a week. Works best on young plants but also kills mature ones. Does not harm the good grass.

SedgeHammer (SH) is great! Two days after application the Sedge shows yellowing and then it's gone. Last year was the first application of SH to our newly laid lawn. Little did we know that tilling the soil would multiply the Sedge, so it was not surprising to see them again this year. They're gone now. ;-)) BTW, the label calls for 2 Tablespoons of nonionic surfactant. That's a bit perplexing to a layperson, but I found that JetDry (for dishwashers) is a nonionic surfactant. It worked!

Best price on the Internet that I could find. Therefore, excellent value plus free shipping. A product that works well on Nut Sedge. Surely have this in my Favorites Folder to come back again.

I spent a good amount of money last year, = replacing grass with Palm Springs Gold, adding Hibiscus and Bird of Paradise plants to my little Eden, feeling assured it was practical, saving water, and would require minimum attention. WRONG ! From the golf course, adjoining my property came the nut grass, = ugly & aggressive =a frontal attack, & shooting up everywhere. Bottom Line = On the offensive ! SedgeHammer's on the job, and showing effects. Sprayed under the mid=day sun, initially fades the grass, while it works down to the root system. Very pleased with the product, and I'm also spreading the word to friends = for your excellent service.

I too had used other products to try to rid my yard of nutgrass. Products like Image and several others. Nothing really worked. I used one little one gallon pack from my local farm n ranch store and voilla, DEAD. It hasn't come back in months and I couldn't be happier! Do use a non-ionic surfactant with no less than 80 percent active ingredient.

I had an infestation of sedge weed in my Saint Augustine grass. The SledgeHammer herbicide application got rid of almost all of the sedge weed. Unfortunately, the herbicide does not seem to have a long-lasting effect, so some sedge weeds reappeared two or three weeks later. However, most of the weeds seem to be gone for good. I would recommend this herbicide. Scotts Bonus S does nothing. The only issue with this and other herbicides is that they are not to be used when the temperature is above 85 degrees, which is almost all the time in South Florida. But with some care, it is possible to use them and (again, with care) they do seem to work.

As it turns out, SedgeHammer is meant to be used before nutsedge has sprouted or is very young, something I missed in the review. I test sprayed some older grass and there some yellowing affect after 2 weeks. I will save the remaining until next spring. It cost far too much to waste!

I purchased the SedgeHammer 1 gallon sample, and applied to all my 1000+ nutgrass. It killed at least 900, so I purchased enough for 40 1000 gallons. The last 100 just got spread and I hope that the last I will see....However, I have enough to try and be sure that it will not return. It has been quite a problem in Ocean City, NJ....and we also have it my Retirement Community. In fact, it is the Landscape people of this large community I went to, to find their recommendations....They said SedgeHammer is the only way to go. So far I am very well pleased, Cy...Doc Woods Community

I have applied 3 applications of sedge hammer with absolutely no effect on any of the plants followed the directions explicitly. I did see the outer edge of one plant turn brown, however, it overcame it and came back green after that. I bought 5 packets so I will apply the last 2 and I think I will double the recommended strength. Couldn't be more frustrated.

  Expert response:
Thank you for your comments! We are sorry that you have not seen the expected results from using the Sedgehammer. Sedgehammer is one of our most popular products for nutsedge control, however, it does take time to work. You should allow at least 2 weeks to start seeing yellowing or browning on the target plants. It generally takes a full 28 days to kill nutsedge plants completely. It is also possible that maybe you have plants other than yellow nutsedge that you are needing to kill, such as kyllinga. Our Nutsedge Identification Guide can help you to identify this plant: http://www.domyownpestcontrol.com/nutsedge-identification-guide-a-561.html We do not ever recommend to use herbicides or insecticides at any rates other than those specific rates on the product label. Using more product than is recommend is not only illegal, but in this case it could be dangerous and/or damage your desirable turfgrass. Please let us know if we can further assist you. We appreciate your feedback and your business!

This is my second time to order this herbicide, and at $115 a bottle you can bet that it must work or I would not have reordered it. Follow directions and use only one level spoon per gallon and nut grass will be gone in about 4 weeks. Be sure to use the Non-Ionic Surfactant for Herbicides with Sedgehammer at the rate of two teaspoons per gallon.

I had a HUGE nutsedge problem that began 3 years ago. Thinking that it was just new grass, I let it go. Unfortunately, I found out this year that it was actually nutsedge and that it was a pain to get rid of it from the lawn. SedgeHammer WORKED!!!! Followed the directions...mixed it in a pump sprayer...sprayed the problem areas and in a few weeks it was gone!! YOU HAVE TO HAVE PATIENCE WHEN USING SEDGEHAMMER!!!! It's not like using regular weed killer that yellows the leaves in a day or two. It takes a week or two!!!!

After replacing a lawn due to nutsedge the nutsedge starting to come back again. After some research and speaking to a real "Master Gardener" I had two choices. Let the nutsedge take over or try SedgeHammer. Applied on August 4, 2013 following the directions carefully and I also viewed video of the application of this product. The nutsedge is dying. This weed has turned yellow as advertised. I can't wait to see this nutsedge in 4-6 weeks after treatment. At this rate I expect it to be dead. Just remember you will have to treat areas where sedge is still coming up. In time all the nutsedge will be gone. I did not cut the grass for 1 week after application. My order was filled quickly. I would purchase from this company again.

Sprayed our back yard earlier in the summer and we were so pleased that it seemed to eliminate the Nut Grass. But, this fall we have it all back. Read advice of our local garden expert here in Dallas, and he said you HAVE to spray again approximately 6 weeks after the first application. So ordered some more and I will try it again this coming spring and try spraying the yard twice.

I applied this over a smaller area than is stated as being effective.  Applied about 2 weeks ago and the weeds look as healthy as ever. No new "nuts" showing up but doesn't seem to be killing the grass like body.

I didn't have a lot of experience with Sedge before we moved into this house. I went down to the local spray store and was sold the wrong product (at a cost of $110). The next time I went in, I took a sample of the "grass" I was dealing with and they sold me this stuff at twice the amount I got it for here. Nonetheless, this stuff works great and I'm winning the battle against the sedge demons.

I ordered several packets of the product online. I used it precisely as directed, letting the nutsedge have at least one full week of time after mowing to attain good blade size so as to maximize the surface to absorb the herbicide. Then I sprayed it covering all blade surfaces and skipped mowing the following week to give the product adequate time to penetrate into the roots of the nutsedge. Within one week to 10 days all the nutsedge had turned yellow and died. The best product I have ever tried for this problem. I recommend it highly. In fact, my lawn service guy saw it and asked what I had used. I told him and he ordered some as well and was extremely pleased with the results.

My nut sedge was totally out of control--it was all through the mondo grass which was impossible to weed. I waited until the temp came down to under 85 degrees and applied it last week. Already can see the results with brown ends. Too soon for the product to totally work but it sure is nice to see the visible results.

I've been battling nutsedge for the past two year with little success. Local nursery recommended a Fertilome product that only yellowed the sedge, only to come back. One application of SedgeHammer and it has killed the nutsedge dead! Be patient, it takes about two weeks to show results. Would recommend to anyone battling nutsedge!!

I spot sprayed the nutsedge. It takes a while but the product works. Read and follow the directions. Buy enough for a second application. It take 2 application about 3 weeks a part to deliver the fatal blow.

As anyone with purple and yellow nutsedge knows, these plants are extremely invasive and tough to control. But SedgeHammer really works. It kills the sedge but (in my yard) didn't hurt the fescue grass around it. In three years I've not been able to completely eradicate it, but every year I see less and less. It's definitely good to have at least one extra packet on-hand. Highly Recommended.
