    Didn't work

    By Amy on 06/29/2017

    I used this 3 times on my veggie garden and it had no impact at all. I foolishly didn't treat or paper my garden this year and it's been out of control. I spoke to a rep from this company who assured me that this product was all I needed for killing/preventing the grass without harming my veggies. This product didn't do anything. Total waste of money.

    Thank you for your review. We apologize you are not getting the expected results. We would like to help troubleshoot. With the Hi Yield Grass Killer Post-Emergent Herbicide a surfactant helps the herbicide stick to the waxy coating of the weeds and lawn you are applying it to. It improves the effectiveness of herbicides greatly. With this product you would need 1 tablespoon of surfactant per gallon of mixture. Please tell us more about what you are treating for so that we are able to locate a product that will best fit your needs. We can also be reached at 866-581-7378 M-F 9-5PM EST.

    Hi Yield killer

    By Ed on 09/04/2020

    I tried this thinking it was a cure for Bermuda grass, but I killed everything which was not my intention. Be careful of application but it does a good job killing everything it touches.

    Grass killer

    By Lisa on 05/17/2022

    If I could give a no star I would. Product didn't work. U can't return if open. Product takes up to 2 weeks to kill. I will not ever buy from this company again.
