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.
