Ortho GroundClear Year Long Vegetation Killer2 Concentrate, 1 gal. | Weed Killer Concentrate, Kills and Prevents Weeds Up to 1 Year

You have to be patient with this product: I dilute it and spray it on leaves with one of those hand pump sprayers, and it works better than anything on thick brush and vines, and raspberries an blueberries too: anything that is a hedge, a thick vine or a thorny invading monster, this product will kill it. Spray it diluted on the leaves and say goodby to what your neighbor planted on your property line after about three to five weeks. Just have patience. I don't think it works on grass, don't know why, so just get something else that says weed and grass killer for that and do not complain that this doesn't work. It's for the heavy stuff.

I diluted this and used it in driveway cracks. Took 2 weeks to work. But it did work. Good if you dont have time to work on the weeds via pulling or torching. But not good if you need an immediate solution.

I bought this to mix in my sprayer because it was cheaper than roundup or spectracide, which I’ve used with success. but when I peeled back the label to read the instructions, I was shocked to learn that it takes 24 oz for a gallon. The others usually called for about 4 oz. I also bought this hoping that the claim that it keeps weeds away for a year is true. We’ll see. I just sprayed weeds in my front yard and back. After about half an hour I see the weeds are wilted and turning brown. If they come back in less than a year, I won’t be buying this again. It’s too expensive because of the dilution rate.

I've been using this product for several years to kill weeds growing up through cracks in my driveway and sidewalks. I use it instead of RoundUp because it does not contain glyphosate. The product works well but it does not prevent regrowth for a year. I normally treat every other month throughout the growing season. I'm happy with the results and will continue using this product.

I use this in all my mulched and rocked areas, as well as the cracks and crevices of the driveway. Great product and does what it says. Must dry for an hour to be effective.

This stuff works great! It kills the weeds for a long time. Easy application. The price is kinda high. I delute it with a little bit of water to make it last longer and it still kills the weeds for a long time.

It will definitely kill anything you put it on.

I am not very happy with this "Concentrate" it kills broad leaf weeds for the most part I want a weed killer that kills and sterilizes the ground around them so nothing germinates or lives. I spray in the cool mornings and just before the sun goes down to prevent rapid evaporation in hot Arizona. I guess I will keep looking for a killer maybe go back to using "Round Up". Or just use some old fashion home mixtures!
