Did not work

It did not work at all. I followed the instructions and I think it made the weeds grow more

Ortho ground clear weed and grass killer concentra

I bought and applied a week ago and got zero results. Looks like I fertilized instead.

We're sorry to read about your disappointment with Ortho Groundclear Weed & Grass Killer and appreciate your feedback. This product is not systemic but kills off the top of weeds thoroughly treated at time of application. For annual weeds, especially if young, this will typically kill them. Also if the weed is mature, no matter what weed, it will be more difficult to control. Some harder to control or mature weeds will need multiple applications. To get the best results plant leaves must be thoroughly and uniformly covered with the spray solution. For best results apply when temperatures are between 60-85 degrees. 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.

Doesn't kill all weeds

Killed all weeds except dandelions. Not a good value due to product/water ratio

Works well

Best thing to kill grass or noxious weeds and still be able to plant there!

Great for killing bamboo

This is the only product that can eliminate bamboo, which is very difficult to kill. Weeds, well, if thats your purpose, go get something else.

Junk

Total garbage, says 1/4 cup to gallon double it, didn't work. Put one cup to a gallon didn't work. Don't waste your money.

We're sorry to read about your disappointment with Ortho GroundClear Weed & Grass Killer Super Concentrate and appreciate your feedback. If the weed is mature, no matter what the weed, it will be more difficult to control. It is important to use this product when weeds are young and tender. The product is rainproof in 2 hours after the application dries. 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. Reapply as needed. 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.

Not a good product

Bought this couple weeks ago and used it twice. Now i get nothing coming out except foam? The comfort wand idea is terrible.

We're sorry to read about your disappointment with Ortho GroundClear Weed & Grass Killer and appreciate your feedback. Occasionally, some crystallization can clog the sprayer. After disconnecting the red plug from the cap soak the spray tip/nozzle in warm soapy water. This may dislodge any crystallized matter. The sprayer tip can be readily pulled off and snapped back on after cleaning. Batteries have a shelf life that will last through approximately two 1.33 bottles. It is possible that the batteries need to be replaced. The unit holds either 3 or 4 Double-A (AA) batteries (depends on the wand version). Replace the old batteries with fresh ones to see if that fixes the spraying issue. If the sprayer motor is running and all of the above troubleshooting has been completed, the sprayer may need to be re-primed. To re-prime, place the container above the wand (either holding it above or setting it on something) and spray for 30 seconds in an area where the product can safely be dispensed. 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.

Turned brown fast!

I don't know why these reviews say it doesn't work. We sprayed it 2 hours ago and the weeds are ready brown! So far, so good!

When it says concentrated I expect this to be diluted with water before use. This is false labeling.

We're sorry to read about your disappointment with Ortho Groundclear Weed & Grass Killer Super Concentrate and appreciate your feedback. This product is a concentrate and meant to be diluted by mixing with water before use. For established and difficult to control weeds, add 10 fluid ounces (1 1/4 cups) to 1 gallon of water. For weed control, add 5 fluid ounces (1/2 cup + 2 tablespoons) to 1 gallon of water. 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.
