20 Best Ground Clearing Weed Killer (2023 Updated)

Ortho always makes a great weed control product, and the Ortho® GroundClear® Year Long Vegetation Killer is a good product, as well. The battery-powered application wand makes spraying weeds much easier than any I’ve used before.

No pumping required, and this makes it super quick to spray large areas. The only problem I had was that the product would not come out when I tried to respray. The applicator battery still runs, but nothing was coming out.

I had to change to a different tube in the bottle, pulling one from another product. Broadleaf weeds died within hours, but grassy weeds required a second spraying. The second time I sprayed I absolutely soaked the weeds instead of just spraying the whole weed.

That worked better. Looking forward to seeing if the spray really lasts up to one year.

The Ortho GroundClear Weed & Grass Killer on the whole is a wonderful and powerful product. Kills weeds and grasses efficiantly and effectively. I used the product for two project one was clearing weeds and a little grass on a pavestone walkway and drive way.

The GroundClear worked very well and quickly, it’s been just about a month and looks grear, not growth has returned. the other project was killing a 10×10 section of grass to then replant with sod. the kill was excellent and the ground appears ready for the sod.

No issues with concentrate mixing, however it would be simpler if it came premixed for large areas. Overall the product worked better than described and effectivly. I recommend this product for any ground clearing project of reasonablesize.

Good product.

Normally I like ortho products. But I used the ortho ground clear weed and grass killer on the seams of my driveway, on areas of rock landscaping where grass and weeds are growing through, and a small patch (10×10) area I want free of all vegetation.

After the first application, the weeds and grass I sprayed began turning brown within 20 minutes. But 2 days later, everything I treated was green again. So, I treated all the same areas a second time and got the same result.

The entire week was sunny and dry, so the chemical wasn’t “rinsed” off the plants. I’ll still use other Ortho products, but I’ll never spend money on the Groundclear product again.

I have been using this at all of our properties for about 3 years. I mix this at 3X the required amount & mix it with HOT water. This product takes about 9 days before the offending bush, ivy, weeds, small tree, vines, grass or whatever you’ve sprayed it on is dead but that plant is not coming back.

This is the most thorough product on the market. 10 stars.

Been using this for 5 to 10 years and thats how old some of the bottles are. Does a great job. Seems like nothing happens and then all turns brown. I think it took about 2 weeks last time. I thought maybe no good but then done! Concentrated so about 2 2/3 ounces per gallon of water.

I’m very satisfied with this product and have ordered twice now. It actually kills the weeds and poison ivy that haunts my yard. I have used it with great result.

I’ve used this weed killer for years and love it. I normally get the 2 1/2 gallon but went with 1 gallon this time. I was shocked when I opened it and their was only a little over half way filled! I paid for a full gallon, not a partial.

Very disappointed with the amount in the container.

This herbicide kills all the vegetation it is sprayed on but does not sterilize so you can replant after a couple weeks. It will also kill woody plants and I have heard some trees if enough gets on them.

Otherwise I haven’t had it hurt trees when spraying climbing vines on the tree trunk. Martins also makes a sterilizer that works up to a year but this is not that product.

awesome weed killer takes a little longer to start killing but it last longer i love this weed killer it stands up to it’s name, Eraser !

This was recommended by neighbor friend with a “beware” attached. He said whatever it touches , it kills. He wasn’t kidding. I love using it on areas I don’t want any growth for about 6months. Great for Fl parts I don’t want to deal with a weed whacker.

For the price, I’ll use this over Roundup.

I spray weeds twice ! once per proper direction and next day didn’t see much result so I double on the amount required and spray it the next day and made sure that I soak it really good and check it out the next day and haven’t seen great result.

I was better off to use round up which work well it was a little pricey and I wanted to try something different. Would not recommend.

I mixed as recommended on the directions and used a tank sprayer to apply this product to a driveway full of weeds. It was a nice sunny day and in the mid 80’s. Sure enough! in about 4 days, all of the weeded area was laying over and turning yellow and then a tan looking color.

In about eight to ten days the weeds were so dried up that I could scrap them up, roots and all, Dried up and Dead! I am very satisfied with this product and highly recommend it to you.

I love it. We had a bunch of trees pushed up & 800’ of ditch dug with the dirt making a levy. The initial spray, all that “very deep hard brush” & grass is still dead. What I go & spray about every 3 weeks is all that underneath that we can’t see growing through that levy of dirt.

The front ditch I’ve only sprayed 2x & it is 100% clear & water running. Those hard wood trash trees, I call gum ball, they grow anywhere a seed lands & the seeds are round looking solid green berry type about the size of “lemon drops”, roundup concentrate doesn’t even turn the leaves yellow & this RM43 kills it!! I agreed to let my mom buy me a thing of concentrate round up cause she swears by it, I put the exact amount of ounces for my 2 gallon sprayer.

One week later, our hard brush & thick weed grass actually grew instead of dying. I tried it once more with 14 oz to 2 gallons. Barely turned hard brush yellow, did kill little grass. I went & purchased our 2nd gallon of RM43 (I would buy the 2 1/2 gallon if it had a pump attachment to pump out the ounces you need cause I’m partially disabled & can not lift, pour & not waste out of that 2 1/2 gallon), made a total of 4 gallons, sprayed all 800’ of ditch, those trash trees that still have berry seeds buried in the ground, poison ivy, poison oak, weeds & thick brush along the back fence we are trying to cut.

Less than a week a later we went back out to the property & everything dead. Went out day before yesterday & still dead, no new things popping up yet. I don’t care what it is, nothing kills 100% to never ever grow back unless you pour full strength peroxide, bleach or some other haz mat chemical that is carried by 18 wheelers.

That will kill deep into the ground for years. Naturally, companies can not make chemicals that strong for general public use. This is just common sense.

I maintain 10 desert acres. The way out of weed takeover by July and I mean farm-like sections of weeds, is to pre emerge yearly! I have to be selective around vegetation and the house directly, but for the furthest areas around my property, I use an atv sprayer.

The first year preemerging, we got surflan southern weed killer, the second year we got TVC. I was worried about the TVC and was looking for something as effective but not as devastating. I saw a video for the RM43 and got it! It seems to have worked great and I like how it kills existing weeds as well! None of the other preemergants did that! I was even still spraying weeds with the leftover mix out of a sprayer.

It left NO Green!! I use Caseron for in and around vegetation and good ol picking them everywhere else every year. Unless I find something as good or better and less expensive, I’ll be buying the RM43 from here on out!.

We have 4 homes spread out over several acres of family property. I keep about 12 acres of the property mowed and cleared. That includes weed eating around each home, several outbuildings, and a very wide, long drainage ditch.

It has become too much for me over the last couple years, so we have using herbicide in place of most of the weed eating. I mixed this product at a rate of 2 quarts in a 25 gallon sprayer. We sprayed a little over 125 gallons of mix over 2 days.

It took about 4 days before we started noticing any effect, but within a week it was obviously working well. Now 2 weeks later the RM43 has killed everywhere we sprayed. As noted in the instructions, it will get into the root system and spread to surrounding plants whether you want it to or not.

Not a big deal to me but it might be to others. Don’t use it in areas you don’t want everything dead. It kills at least twice as much as you intend it to. I think the prices are ridiculous but if it lasts a full year, it will be worth it.

I used the Ortho Ground Clear Super Weed & Grass Killer as soon as it started to get warm in Northern VA and it quickly killed the weeds down to the roots, before they got the chance to spread. The product was easy to use, the sprayer head has built in flexible tubing allowing you to plug into the container and carrying around.

The sprayer can be controlled to spray a stream or foam. The spray stream allows control to get into cracks or stay away from plants and flowers. The killer is effective and kills the weeds down to the root.

The weeds have not come back after dying. The Ortho Super Weed & Grass Killer is a quality product and seemed to work better than other products I have used in the past. I feel that this product by Ortho is safe to use and I trust the Ortho Scott Miracle Grow products that I have used over the years.

I finally had a chance to use this Ortho ground clear on a few broadleaf weeds I found in my mulch area. I sprayed the weed in the afternoon after I watered my grass and after about 24 hours they looked wilted and brown.

Perfect kill!! Now onto the pump sprayer. I’ve used similar products with battery powered spray wands and I wasn’t that impressed. This sprayer is just a simpler spray wand. The product comes out as fast as you can pump the handle and then simply hang it on the side of the container when your finish.

I’m summary I would say this is a 5 star plus product. If I can get good weed kill in cool spring weather then I know I’ll get great kill in the summer heat. HIGHLY RECOMMEND!!!.

I don’t know why this stuff is so good. Some sort of secret Ortho sauce. I have tried so many other brands and potions on Amazon, and this is still the champ. I always see results in 24 hours. and it does keep it clear for the season.

I live in a desert-ish climate, so maybe the lack of humidity magnifies its power for me, but this is a great product. I have to buy multiples and use a backpack sprayer. My only point of dissatisfaction is the lack of availability of the concentrate version at the time of this writing.

The concentrate can produce 5 gallons of solution for near the same price. But the product itself – 5 stars all the way!.

We have an 18×10 area that is mulched and covered in crafted metal animals and lawn art, antique ox pulled plow, carousel horse, etc. It doesn’t look great when it is covered in weeds that grow through the supposed weed mat.

I tried the normal ground clear products and no results. Then my Tractor Supply associate told me about this product. It works like a charm! In a few hours, start to see a little brown in the weeds and in two or three days everything’s dead.

I use it 2x a year and no issues. I also use it on our parking pads, flagstone patio, sidewalks, and in our mulched backyard area. While it seems more expensive, it really isn’t, because you mix it with water, so you can make gallons of it for your sprayer.

7. 4 fluid ounces of RM43 per gallon of water, up to ten gallons, with a maximum application rate of 7. 4 fluid ounces of product per 1,000 square feet (2. 5 gallons per acre) per year. 74 x 0. 125 = 9.

25. 9 and 1/4 cups RM43 + 10 Gallon of water in my 10 gallon pull sprayer. Used for Kudzu. I can’t possibly spray the entire kudzu field below my property so I sprayed just along the edge to try and keep it back.

New kudzu grows right over the top so I think just keeping it mowed back works better and less expensive. This spray will kill everything.

I sprayed, and sprayed all my unwanted weeds and 48 hours later they look just as healthy as if I sprayed them with plant food! There was no wind. Temperature was a warm 75 degrees. Completely saturated.

And nothing happened. No difference. Paid a small fortune for this stuff. Said money back guaranteed with receipt but to my usual luck I tossed it out. Buy again? NO WAY!!!.

I bought this product for my gravel RV parking area (as is says on the label it is good for. ) I followed all instructions, have had no rain, and the daytime temps have been in the 70s and 80s since using.

I noticed the area sprayed (not heavily covered in weeds, just a few here and there peaking through the rock gravel) had not reacted to my first application. So I applied again spraying each weed liberally yesterday.

To my surprise today, the weeds really don’t look like they have been sprayed. In years past I always just bought the regular Roundup grass and weed killer and it started killing the sprayed weeds within a day.

I thought this product would not only kill the weeds, but also keep them from growing in the future. This is hilarious, because they won’t even kill the few weeds that are growing now. What a waste of money! I should have just bought the regular Roundup that costs less.

I feel duped!!! Don’t buy this product!!.

Used this as directed on May 31 in central Georgia. Killed everything quickly BUT then it started raining early July and the grass has grown quickly from then to now – July 11. And yes, it is the same grass I used this on in late May.

Same thing with the weeds I used it on at the same time and have the same results. Only kills for approximately 6 weeks not even close to a year.

For the first time in 30 years of home ownership we had a yellow jacket invasion this year. I have effectively destroyed three different ground nests with this spray! I have tried 6 different types of wasp/hornet sprays and found them all to be lacking, from the clear liquid to the other “foaming” products.

The Ortho home defense spray is thick foam, like shaving cream almost, which sat on the ground and trapped the YJ’s as they tried to reenter or leave. Death from above in my case. I am currently battling an established colony in a ditch bank and need more product! My local distributor has been out for 2 weeks and the YJ’s are returning (I plan to dig this out in the winter).

This product has the knockdown power you need. Stock up if you’re in an area with limited distributors; it goes fast!.

This is the best product for killing weeds that I have found. In less than an hour treated areas begin to wilt. Dries fast and is ra\inproof in a matter of minutes, no need to wait for a sunny day that will be followed by three rain free days that many products instruct you to do ( and they still do a poor job)! Three cheers for Roundup! Easy to use and GREAT RESULTS!.

Works at it’s own speed depending on which broadleaf you have. Some weeds start wilting in 48 hours, some in 5 days and others 7 to 10 days. I’m on day 11 and I have some weeds showing no signs of dying.

I’m thinking those wont be killed. I applied a little over the recommendation without hurting our Saint Augustine lawn. I waited until we had a day high of 70° and a night low of 50°. I might apply a little stronger next time I apply it.

I’ve used it for years and find that its potency diminished in storage. Needs to be used within 2 years once opened. Stored in Florida heat might be the reason.

My order arrived in a completely sealed plastic bag packed in the delivery box. The cap had been securely but awkwardly taped down and the underside of the cap had been siliconed. All this was done to prevent possible spillage since the seal of the bottle had been opened.

I was disappointed to see that I hadn’t received a completely sealed gallon. Aside from this, all is well. I hope that this was an isolated incident and that future purchases will be free from defective or altered products.

I mixed and applied as close to instructions as possible. It has been a week now since I applied to my entire lawn; I have noticed several weeds turning colors and looking weak, but nothing has died yet.

I also noticed that this did absolutely nothing for the clover and a few other odd weeds in the lawn. I will most likely have to reapply.

On line transaction was fine, and the product is fine. The problem was with the delivery. Apparently the gallons (2 single gallon) leaked in the shipping box, so the shipper placed the ruined box and the gallons in a large plastic bag closing it with a large Rubber Band (what a joke).

The package was delivered a day after I had a Bladder Procedure, so I could not lift the package. My wife took it to the garage for me to check it later. When I was able to deal with it I notice the gallons on it’s side in the ruined box.

There was more leakage. I right sided the gallons and discarded the box and the plastic. I do not know how much of the Fluid leaked. AS of today 12/29/21 I have 3 different Walmart phone number directing me to different DEPT.

and not one person is willing to help. I.

I’ve picked up both the concentrate and ready to use version of this a few times. The ease of using this in my garden beds and on the patio make it a lifesaver for my back. It also saves me time. By the time I finish spraying, I already see the grasses and weeds I started with wilting.

The directions are clear and the flowers and plants around what I spray never have a problem. Definitely would recommend this for every gardener.

The delivery in the order was great. But the product did not work as advertised followed you directions oversprayed the weeds and then shot them directly. They’re still there summer brown at the point of contact however it did not kill the weed.

Not happy with this product would not buy it again.

First time I used it, the entire quart worked great. The last 2 quarts haven’t been as good. At first I thought maybe it was me and the amount of concentrate I mixed. My last and final solution was 4.

5 oz in 1. 5 gals. Didn’t kill any of the weeds and grasses I sprayed. Very disappointing. I do not recommend this product.

Kills efficiently and quickly. Also prevents future growth. This product has been around for decades so it has a proven track record on farms. It keeps my vacant lot free of unwanted growth.

All weeds are g o n e after just a few days of applying it to me my lawn with ny backpack sprayer. It worked so well I just ordered a gallon for regulate preventative maintenance.

i used at recommended strength and drenched the weeds directly. it worked for some but not all that were listed on bottle. took like a week to notice the weeds dying but 2nd go around i doubled dose and spot treat to the weeks a week later the others gone.

I used the weed and grass killer concentrate mixing 7 oz with one gallon of water but lousy results. I am totally surprised. I’ve had real good results in the past but not this time. I noticed when I poured the liquid concentrate into the spray container it looked different than before.

Did the manufacturer change the ingredients?.

I have used many of the expensive name brands over the years, but picked this brand up last year because of the much lower price. I was skeptical that it wouldn’t perform well or would take much longer to work, but to my surprise it worked better and much faster than the other brands (the grass and weeds are completely yellow and dried up in usually 24 hours).

I have continued to use this product and it still works just as good as the first time I used it last year. Hopefully the price and results stay the same, as this is the one I will continue to use! I highly recommend this product.

Took about a week for full effect to take place. Nothing lived that was sprayed. Definitely worth buying the concentrated version. Have patients and it’s worth the value

I bought this product to use between the cracks on my driveway, when weeds like to germinate. I use it 2x, during Spring and late Summer. This small container is more convenient to use than some of the larger containers.

That was also a consideration in deciding to buy this product. I also like, and use Ortho bug killer (good for 12 months, although I apply monthly on my porch in SC) in and around my back and front porches (once enclosed and the other open).

It is also very effective. So, I guess I like Ortho products. :).

Great product! Good trigger, sprays far and visible results in about 20-25 mins. Recommend the product for those annoying weeds out back and growing in the cracks that you just can’t pull out

Two applications haven’t killed the morning glory-some browning but the plants are still putting out new leaves.
