Herbicide - 1 Pack of 1.33oz Bottle of USA-Made Post-Emergent Nutsedge Killer for Lawns - Lawn & Pet Safe Weed Killer for Commerical & Large Area Use - Also Works on Horsetail & Kyllinga

At first, i didn't think it was working. After about 10 days, i noticed that the nutsedge was starting to change. It began to turn light brown, then after a month, i could tell it was working. I had a lot of the nutsedge in my yard, and i couldn't stand them i tried a few other things, but nothing worked. This Sedgehammer is a bit pricey, but well worth it

This stuff is truly amazing. We have St. Augustine grass and about 5 spots were growing nut grass the last couple of years. One spot about 8’X8’ was total nut grass, all the st. Augustine had died. I used as directed. Mixed 2 gal twice over 2 weeks. I thought it was a tiny dose but this stuff has killed my nut grass and has not harmed my grass. I never would have believed it. This is the perfect product and does exactly what it claims to do. The bottle has enough that I could let all my neighbors use it and still have product left.

This stuff works!

The good: It didn’t kill existing grass and it appeared to work 1-2 weeks after application. The bad: my sedge has grown back I guess it’s time for another round

This is my second year using this product. My yard was initially overrun with Nutsedge and some Kyllinga, and this product worked perfectly. Both of these weeds are nearly impossible to control in bermudagrass (cannot use mesotrione for pre-emergent control in bermuda unfortunately). It is a little pricey, but just buy the bottle and don't be a sucker for the lower price on the small packets. As this is not a preemergent, so you will need this product continuously throughout the spring and summer on new weeds that emerge. It will require more that a couple little packets. Overall, it is easy to use, works substantially better than other products for nutsedge, and worth the price. Tips: - Mix as instructed on the label, but add a couple ounces of blue dye to the mix. - I bought a cheap 1 gallon sprayer just for Sedgehammer. I use it about once a week on any new nutsedge or kyllinga I see sprouting up. Never use twice on the same weed within 14 days per the product label, and that is what the blue dye is for! If you have already sprayed a weed, it will still be slightly blue from the dye. There is really no reason to spray weeds twice with this product anyways. - Spray when weeds are young. This requires spraying about once every 1-2 weeks to catch them before they get too big. Kills nearly 100% of the Nutsedge if you catch them in the early 3 leaf stage. It does take about two weeks to turn weeds yellow and a month to fully kill weeds. Resist the urge to pull Nutsedge, it seems to make the problem worse. - Know what your spraying! It has a fairly narrow spectrum of weeds it will control. Don't waste your product on other weeds or use more than is necessary.

Very impressed in a southern bermuda lawn. I have a large property. I mixed all 1.33 oz in a 32 gallon sprayer with surfactant. Pulled at 4-5 mph and targeted about one load per acre. I know it's supposed to take a while, but I did note after 3-4 days, I had browning on the areas that got a larger dose due to speed or overlapping. Some areas that got a lighter dose still look green after about a week, so we will see. I will follow up with a second round later this year and will concentrate it a bit more. I was worried about how it would affect the bermuda, but suprisingly, zero stress on the grass, so next time will be stronger.

This product is a one trick wonder. Mix it up per the directions, spray it on the type of weed it is specifically designed to kill, and it kills it! I am about to make my third pass around my yard trying to wipe out all the spurge poking its head up in my zoysia lawn. Whereas originally just a couple of days after I mowed there were dozens of spurge plants poking their heads up all across certain sections of my lawn, this pretty much ended after my first round of spot spraying. And a few very mature spurge plants hiding in one of our flower beds were wiped out with that first spraying ... without any noticeable damage to other nearby desirable plants which may have been hit by over spray. But there were still a few showing up here and there that I had missed ... just not as obnoxiously as before. Now I have noticed a few of those ugly heads showing up scattered around in various parts of my lawn which I hadn't seen before, so I want to hit them one more time this fall before they overwinter and then show up again next spring. It is an expensive little bottle, but it works like a charm without damage to my lawn or other nearby plantings ... and now I have a ten year supply for any that does show up later!

I still have some nut grass. Hoping no roots get under my above ground pool!! It got rid of some. I need to reapply it I’m sure & I will.
