Ortho Nutsedge Killer works great

I have had a huge Nutsedge problem in my yard for years - my lawn always looks great in the spring but as soon as the St. Louis heat starts up so did the Nutsedge. Over the years I have tried everything and nothing seemed to work until I found Ortho Nutsedge Killer. This product worked perfectly on my lawn and did not kill the regular grass - (I have a mixture of Tall Fescue / Bluegrass / Zoysia). I have a very large yard and it took a few bottles to get the Nutsedge under control and then a few spot applications as some new areas started to spring up but my yard has never been this free of Nutsedge in over 20 years that I have lived here. I always spray the Nutsedge a few days after I mow, because it is easy to see as it grows so much faster than the regular grass. I then can see it turn brown and die and by the next time I mow it doesn't come back. Hopefully I won't have any new Nutsedge next year but if I do, I know how to get rid of it now. Thank You Ortho for making a product that really works.

Effectively kills nutsedge, but needs more user-friendly means of application

This product kills nutsedge as advertised, but it is sold only in a small pump bottle which creates two problems. First, the small spray bottle requires me to bend ever further over to the ground as the level of the fluid decreases in the pump bottle in order to keep feeding fluid to the sprayer. A solution is to combine remaining amounts of fluid from bottles into a single bottle that is kept full, but this is hardly an optimal solution. Second, by the time I discovered this product, the infestation was widespread, so it requires tedious application using numerous small spray bottles to cover the several large areas of infestation and widely separated emerging clumps of nutsedge. It would be great if this product could be made available as a concentrate suitable for a hose-end sprayer or tank sprayer, but Scott indicated to me last year that they have no plans to market the product other than in the small spray bottles. Application problems aside, this is a great product that takes care of nutsedge.

I have struggled with Yellow Nutsedge in my lawn for over 5 years. Professional lawn treatment services could control it, but when I switched to taking care of my lawn all by myself, this weed became established in my lawn and got worse with each year. A few years ago I tried a herbicide containing methanearsonate, but it yellowed my yard considerably for a few weeks, and the nutsedge came back. Two years ago I paid TruGreen for a single application to treat it, but the nutsedge came back. I bought a bottle of Ortho Nutsedge Killer at WalMart last year and used it on my worst patch of nutgrass. It worked great, killing the nutgrass, and not damaging the lawn. I went back for more and it was sold out for the year. This year I bought 8 bottles, and have used 5 of them so far. During mid summer, I have to walk the yard a couple of times a week with a bottle, spraying all the nutsedges I see, but it then kills them.

This KILLED my nutsedge

In July, Day 1... At 6pm I sprayed the patches of nutsedge all over my front and backyard during 80 degree weather. 24 hours later, the previously green nutsedge was turning yellow/brown. On Day 3, it rained for 30 minutes, hopefully pushing the poison down into the dirt to kill the bulbs of the nutsedge, and there was more wilting and dying. On Day 5 before mowing the lawn, they were wilting and brown even more. AND this was all during days of 90 degree summer heat.... my grass was hardly damaged; there were two small patches probably where I sprayed a bit too much. On Day 7, after mowing you can barely see the nutsedge that is left. Now to be honest, I had the same results last year, but some still grew back. I guess it'll take a few years to get rid of it all. Good luck!

I have st augustine grass and it was being choked out severely by nutsedge..I bought the nozzle type hose attachment sprayer and covered my lawn with the product...well it started to work in a couple days and it kept working for a few more weeks it killed most of it but if you are heavily infested with sedgegrass You must be prepared for dead looking grass around for a while if you spray too late in the the nutsedge dies off it leave spaces where theres no grass. spray in the summer before the fall growth spurt when it gets cooler.. as now I have to wait until spring for my lawn to thicken up where the nutsedge was thick, and Im now seeing clovers filling in the areas before the grass can...but at least the nutsedge is defiantly works! I am planning on doing it again but this time right before my grass has a growing season like early spring...

The hose attachment type is 1.4 % active ingredient and the ready to use is 0.05. Thats 28 time more dilute. So if one uses 1/2 a cup (4 oz) of the hose product and adds 14 cups of water (14 x 8oz +112oz) it almost equals a gallon (128oz) of the ready to use concentration. I'm trying this at the moment in my pump sprayer.

Used in flower bed trying to clear for planting. Made some of the nutgrass sick but killed none.

Comment from Amanda - 9/26/2016

We are sorry that the Ortho Nutsedge Killer Ready-to-Use did not control the nutsedge as expected. To get the best results from any weed control, be sure to apply the product when your daytime high temperatures are consistently between 65 to 85°F. Since this product is absorbed through the weed's foliage, we recommend that the weeds not be mowed for two days both before and after the product application. This product will only kill weeds that are actively growing at the time of application, and cannot prevent new weeds from germinating. We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please contact us to see what can be done.

Used this product to knock my nutsedge back in several places, but it has killed the centipede in three places of main application. The only thing left is dead grass and bare dirt. Doesn't seem to hurt the bermuda that volunteers up though. Very disappointed because I was using another product that DIDN't kill my grass. May have to re-sod the three areas. Will be contacting customer service for help.

I like this product but must use caution as it will "kill" the grass if it is left to long on the sprayed area (I use the hose/attached bottle). I also used the Ortho dial-a-spray bottle for diluting other Ortho products and was wondering what the attached bottle orifice is as I'd like to put the setting on half on that of the attach bottle.

Killed nutsedge but browned grass

I have a nutsedge problem in my back yard in north central Florida. I applied it to St Augustinr grass which it says is safe. It saw great results within 48 hours and noticed that the nutsedge was dying. However, my grass has turned yellow and looks really bad in the days since. I know the bottle says that stressed lawns may discolor but I'm a little worried that I've killed my lawn. I'll give this better reviews if my lawn comes back, just be cautious with this product and try it on a small patch first.

I have tried lots of different weed killers that did absolutely nothing to the spreading nutsledge patch I have in my lawn. I'd never seen this week before last summer. My regular Scott's Weed & Feed treatment worked on everything else. Applied Halts twice very early this year and again a couple of moths later. I live in a warmer climate and of course the winter was very mild this year. It was still there when my bermuda started to come out of dormancy, so I tried this product. It killed the nutsledge dead! Just wish I could buy it in "mixable" form on some other spots with just a small infestation where I see just 4 of 5 of the blades coming up fast! I highly recommend this product.

I bought this product to try and kill and stop the spread of weeds in my yard. I live in central Texas and have St Augustine grass for my lawn. I used this product on the whole yard and, after a week it looked like i just feed all the weeds is is suppose to kill! I will plan on try to get my money back for wasting my time!! I have resorted to trying and pull the weeds by hand!! I am in the process of finding a product that can produce what is says it can!! I would not recommend this product at lest for St Augustine lawns!!

So for 3 years I had the lawn that looked like it grew in spots overnight after a cutting. My mailman said I had nutgrass. So I research it and its not grass but a weed.....this season I was sick looking at the high grass. I did online research and found Ortho Nutsedge. I tried it in 3 areas and waited .....BOOM!!! the stuff turned brown by the 3rd day and after 3 weeks it never grew back. I purchased a few more bottles to finish the property. I had to treat 5/8 of an acre and the spray with hose system was great!! Easy to use and it did not kill my real grass. It killed off some other weeds too -BONUS!!! Yes by this and stop lookin at your tall green Nut Grass.

Used to the direction, has browned or killed my tall fescue, nutsedge still growing. Do not use, use a spot treatment, not a broadcast spray. Just keeps getting worse, after 2 weeks of almost constant rain it just kills more lawn and nutsedge is still present.

Used 2 weeks ago on yellow nutsedge in St. Augustine grass - it works! Want to retreat new patches and VERY disappointed to learn this product isn't available in (at minimum) a 1 gallon refill bottle or (at maximum), a 1-2 gallon bottle with *easy* spray applicator. I am a jr. baby boomer, and as such, suffer from a bad back and tendinitis in my elbows (which your spray pump exacerbates). I strive to be *green* and will not waste water with hose application. There is no reason why product in gallon sized jugs could not be poured into a pressurized spray applicator for those of us with large infestations (and aging backs and elbows).

Killed Oxalis & Violets

This product is easy to use. Was able to spray weedy areas for about 5000 to 6000 square feet with one 32 oz container connected to garden hose. Have had trouble killing Yellow Woodsorrel (also called Oxalis) in the past, and with this product in 2 days it was brown and dying. Temperatures were around 75 F when applied, and my lawn was well watered from rains the week before use. The lawn looks great - no yellowing or other damage. I anticipate doing one more application later this fall to deal with a few areas missed. The Nutsedge is yellowing, but as of this review it is too early to tell if it will be completely dead.

For 3 yrs now my neighbor and i have had this weed in our lawns. My lawn is like a golf course and i would always pull this weed out manually. After doing research on Nut Grass and seeing whats available to use i came across this product by Ortho. After reading the reviews of this product i tried it this month. In just 2 days the nut grass turned yellow and is dying out. I wish you could get this product in a larger bottle say 64 ozs. so you could use a pump sprayer to cover your entire lawn. I would highly recommend this product to any one, it works great.

While some other weed controls are not 100%...this one works for me every time. Within a few days of spraying the area, the nutsedge starts to yellow and no grass is harmed. I have only used this in small areas at a time so I can't speak for a really large area. I would think you'd need a better way to apply but it should still do the same good job. The only downside is the bottle is hard to use up as when its low, any angle stops the spray from working...and you can't hit what you want without angling it down to the weeds.

I have tried numerous products and nothing worked. I had clovers, dollar weeds, and other stuff!! This killed everything but my St. Augustine grass. It takes a few weeks to work, but it will take care of your weeds. Wouldn’t use anything else, it is expensive but it really does work!!! One more thing I was shopping at Lowes and someone was looking for a weed killer, guess what I did I told him to go with Ortho® Nutsedge Killer for Lawns its expensive but it works and he purchased the Nutsedge.

I had huge issues with nutsedge growing like crazy on my fescue. I tried pulling them up one by one every day and they kept coming and coming. I did not even know there was a product to treat it until somebody recommended this one to me. I was hesitant since other Otho products had not worked. This thing works like magic. In a couple of days the nutsedge turned yellow and then died. My fescue grass was intact! I just wish it was a little bit cheaper.
