Sedgehammer 51516 Herbicide, Clear

This really works on Nut Grass. I used it last year and it was gone. I should have applied it again in January or Early February. By late February it was back! I had to kill it again. I waited to long and let the grass get 6 to 8" high. I won't do that again. It's on my calendar for next year. I only have a couple of places I need to spot treat on 2 yards. I think that's really good.

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.

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!

5 days after mowing when I could see the Nutsedge growing I sprayed and it halted the Nutsedge growth until next mowing. Five days after next mowing there was still Nutsedge growing but less this time, sprayed again and it halted it. I'm now on the 4th iteration and it's less each time and nearing the end of Nutsedge season, so I will pick this up again next year. I believe the Nutsedge root system has already grown and continues to grow to a new location prior to the spray being able to kill it is why it's still coming up and you just have to be diligent with the product so I'll keep on it to get the last of the root system from it's new growth. My neighbor has it as well so I don't know that it will ever go fully away unless he sprays it too (will creep back in each year underground). One pain is you have to mix the product, but it comes with a small spoon per gallon so not to bad for that, but it also requires a surfactant to be mixed with it (I got Hi-Yield Spreader Sticker from a local hardware store) - 1 to 2 teaspoons per gallon. It's a little messy to pour. Some online says you can use Dawn dishwashing liquid while others recommend to use only surfactants made for foliage so I'm sticking with that unless I run out and need quick solution. I have been fighting the nutsedge for several years now using different products (name brand hose spray last few years) but it only halted the growth after spray and came back full the next week - so I'm giving this Sledgehammer a try for the next year to see how it does. I'm hopeful in what I'm seeing as a reduction week over week that it may actually work. The cost is high but it does make 40 gallons. And you have the pain of having to mix it with a surfactant sticky liquid so that it will stick to the nutsedge, but I'm willing to do it if it will get rid of this insidious weed!

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
