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

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!

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.

Kills nutsedge with two applications. This stuff works!

I purchased this product from Amazon and given some patience, it does the trick. A couple watch outs... Use a good surfactant as recommended to ensure that the product clings to the blades. I used Dawn dish liquid as others recommended and it seemed to work just fine. Add the surfactant after you have thoroughly mixed up the sedgehammer in the sprayer. I made the concentration 1.5 times stronger than recommended just to ensure that it was strong enough. Expect to apply the product numerous times about a week apart as this process takes time. I also found that lightly watering the ground a little the next day or two helped carry the product down to the roots better. One note of caution, once you think you have killed all of the nut grass...water the area, everyday lightly for about a week and see what emerges. If any nut grass reappears, treat the area again! Although the 1.3 oz bottle is pretty expensive, it is much more economical than buy the pouches that only mix up one gallon of product. Believe me, you will not be sorry that you purchased it! Good Luck!

I don’t usually write reviews, but I figured this product and others might find it helpful. My front and backyard were infested with Sedge Weed after several weeks of constant rain here in Houston. I treat my yard with pre-emergent, weed and feed, and fertilizer with iron, but the rain did a lot of work on it. Did some research and I found that this was the most effective treatment in addition to a surfactant. It may be a bit more pricier than others in the market plus the added cost of the surfactant of $12, BUT it was absolutely worth the upfront cost and it will last a while.I picked a day to finally treat it thinking it was not going to rain, but it actually did while I started my treating. I thought it was going to be a loss but it still worked. I sprayed loosely on all the areas of the weed and around the generally area if they were in clusters.It rained the next couple of days non-stop. When it finally cleared up and the grass dried up, I was able to cut the grass. All the Sedge Weed and areas that I treated were basically gone to the root. I’m very happy with the product and I would definitely recommend this product to everyone. Make sure to read the instructions for the most effective results. I also treated areas in my flower bed because the Sedge Weed was really taking over.The pictures I have are 1st day after, 2nd day after, 3rd day after 5 days after, 1 week after, 1.5 weeks after, and 2 days after cutting the grass. Yes it took a week and half to cut the grass because of the rain, but 98% of the Sedge Weed is gone. There are areas that I’ll have to retreat because I just missed it on the initial day of treating, but once again I’m VERY happy with the purchase. Worth every penny and it will last for many seasons. BUY IT!!
