Great Clear!!

[This review was collected as part of a promotion.] This product does exactly what it states it does. It will kill grass and weeds with ease. The bottle is ergonomically friendly, making pouring extremely easy. I saw results within the hour. I am very happy with this product.

Works as advertised.

[This review was collected as part of a promotion.] This product is very effective and works on killing weeds and grass. Great for eliminating weeds and grass growing up in landscape areas. Easy instructions and easy to apply. Effective on large areas too.

Hi, 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 plant leaves must be thoroughly and uniformly covered with the spray solution. If the application does not cover the entire plant, the control will be less and a reapplication will be needed. If the weed is mature, it will be more difficult to control. It is important to use this product when weeds are young and tender. You can reapply as needed. 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.

We're sorry to read about your disappointment with Ortho GroundClear Weed & Grass Killer Super Concentrate1 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. If the weed is mature, no matter what the weed is, it will be more difficult to control. This product is NOT systemic but kills off the top of weeds thoroughly treated at the time of application. For annual weeds, especially if young, this will typically kill them. Do not apply when rain is expected within 2 hours. Do not water for at least 2 hours after applying. To get the best results plant leaves must be thoroughly and uniformly covered with the spray solution. 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.

Great Product

I discovered Groundclear three years ago. I use it to fight ground ivy. It works on weeds and tough brush as well.

It sucks

I used to gallons on my driveway and it did absolutely nothing and my driveway is covered with weeds again. Never had an issue with using this before.
