Guests are saying
The product has received mixed feedback from guests regarding its effectiveness in killing weeds and grasses. While some guests report quick results and effective weed control, others express disappointment with its performance, noting that it does not always kill weeds to the root as advertised. The ease of use and concentrated formula are appreciated, but issues with the sprayer and inconsistent results have led to frustration for some. Overall, it may work well for certain applications but may require multiple treatments for stubborn weeds.

Just okay
I live on the shore of a bay and we have grasses and weeds popping up in our gravel driveway and in some of our flower beds and Groundclear just worked fair. It did not kill the roots and just about everything grew back. I then doubled the dilution and tried it again, but had the same results. It does not permanently kill weeds and grasses like it states and I saturated some areas.

Didn't work
Sprayed the needed areas (overgrown gravel driveway) four days in a row because the killing wasn't complete. We went on a trip for 5 days and when we got back you could hardly tell it had been sprayed.

We're sorry to read about your disappointment with Ortho® GroundClear® Weed & Grass Killer Super Concentrate and appreciate your feedback. This product will control listed weeds when applied according to the label directions. Some harder to control or mature weeds will need multiple applications. If the weed is mature, no matter what the weed, it will be more difficult to control, so it is important to use this product when weeds are young and tender. We want you to be confident in our products. For this reason, we offer a product guarantee. If for any reason you, the consumer, are not satisfied with the results after using this product, you are entitled to get your money back. Limitations apply.

Waste of money
Didnt turn a single weed brown. Used almost the entire gallon on a strip of weeds/grass along a fenceline. The grass didnt even die, which typically only happens when you dont want it to. I wanted it killed and no luck. Go to TSC and get something better.

Hello Brett. We're sorry to read about your disappointment with Ortho GroundClear Weed & Grass Killer Super Concentrate and appreciate your feedback. 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 (18 to 29°C). For best results, the nighttime temperatures should be consistently above 50°F (10°C). Lower temperatures will cause the product to work more slowly. This product is not systemic but kills off the top of weeds thoroughly treated at the time of 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. If for any reason you, the consumer, are not satisfied with the results after using this product, you are entitled to get your money back. Limitations apply. At your earliest convenience, please reach out to us at 866-324-9192 if we can further assist.

Do not buy!
Ortho ground clear weed and grass killer 2 concentrate. Doesn't work. It turns the weeds and grass brown then it's back green within the week. I put whole bottle in sprayer. Waste of time and money.

Roxy123, we're sorry to read about your disappointment with Ortho GroundClear Weed & Grass Killer Super Concentrate and appreciate your feedback. While you should see browning and yellowing within 15 minutes, it may take longer for the plant to die. It is important to use this product when weeds are young and tender; mature weeds are more difficult to control. If it rained or the area was watered within 2 hours of application, the product may have been washed off. To get the best results, plant leaves must be thoroughly and uniformly covered with the spray solution. If the weed is not listed, this product may not control it. We want you to be confident in our products. For this reason, we offer a product guarantee. If for any reason you, the consumer, are not satisfied with the results after using this product, you are entitled to get your money back. Limitations apply.

I must have super strong weeds. Followed directions. 3 applications and only the young small weeds kicked the bucket. Sucks!

Hi Donald, we're sorry to read about your disappointment with Ortho Weed Control and appreciate your feedback. Mature weeds will take longer to die. Product could have been washed off plant. Temperatures below 60 degrees or above 90 degrees may cause weeds to be dormant. Cold nights may delay weed death! Product will still work, but will take even longer. Drought stressed plants can not readily absorb the herbicide...water them first wait 24hr. When leaves are dry, spray again. Mowing 2 days before or after application reduces leaf surface and plant's ability to absorb the herbicide. Reapply 2-3 weeks after first application. 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 reach out to us at 866-324-9192 if we can further assist.

Poor
I've followed the directions. I never sprayed mature weeds a second time. Some massive adult weeds died very well, some midgrowth weeds were not affected. Does kill grass well, I never intended to use this on the lawn where weeds were, but the regular weed killer is even less effective. Not sure how long I should wait to plant grass again. The bottle says for organic gardening, that implies the half life is very fast then.

Awesome Timesaver!
I won’t use anything else! Just be sure to give it a chance. I always spray at dusk when there’s no or very little breeze and no rain is forecasted. Then, in the morning, I go back over the older, more established weeds. It can take a couple applications to kill the thick ones. It isn’t made for tiny trees or anything with a thick, solid stem. Also, I see a lot of people can’t get it to work. Here’s what works for me. Remove the sprayer. Make sure the cap on the jug is in the OFF position. At the end of the curly hose is a nipple cap. Push the nipple onto the cap of the jug until you hear a ‘click’. Open the arm on the sprayer until it clicks in position. Remove the tiny paper tab that engages the batteries. (If it’s missing, you may have to replace the batteries.) Slide the tiny clip to the UNlocked position and turn the cap on the jug to OPEN. Point the sprayer away from you and close to the ground. NOW squeeze the handle while pressing the button to dispense the product. To put it away, work the instructions in reverse.

Gets It Done Big Time
A very hi performance product, where more is better when mixing just wastes this pricy product. Be VERY careful where you use this product, strongly suggest not to use as an lawn edging supplement because it will migrate deep into the soil and spread after watering/rainy days and will definitely harm existing grass or foliage several months down the line. Lastly, give it time to work and it will. Yes it’s expensive yet well worth every penny in the long run

Worthless product don't waste your money
What a worthless product! First is the insane amount of product you need to mix per gallon of water. Second is the poor performance. Six weeks after soaking an area to runoff I have new weeds popping up. And not just one or two. Dozens. I sprayed a six foot by fifteen foot area with over a quart of mixed product for the above results. I don't need it any more but held a 3OT spray license. This is not something that you just walk in and get handed to you. I feel this gives me a bit of incite on how these products are used. If I could I would give this product zero stars.

Incomplete/ non existent instructions for use
My mom bought this to eliminate weed growth around her house. When I went to spray the areas for her, the comfort wand is not working. Batteries are good, but there are no instructions on how to prime it or anything other than plug the hose end into the top of the bottle. The dial on the bottle is turned to ON. And the nozzle is also set to a spray pattern and not an Off position.

We're sorry to read about your disappointment with Ortho Home Defense Insect Killer For Indoor & Perimeter2 and appreciate your feedback. Potentially the siphon tube and sprayer needs re-primed, place the container above the wand (either holding it above or setting it on something) and spray for 30 seconds. If the Wand begins to spray well at the end of 30 seconds you should be able to put the container down and continue spraying. Please give us a call for additional troubleshooting or replacement part availability. We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers.
