The product works very well on what it covered, but it only came out in a stream. It should have been a spray. Therefore, the coverage was very uneven.

reply from Roundup Consumer Services

Thank you for sharing your feedback about Roundup Weed & Grass Killer. We value your input and are always looking for ways to improve our products and your experience.There is a few factors that will cause the applicator to not spray well such as how long you have had the product and If was used before, there might simply be some product dried in the tip. Simply soak the tip in warm soapy water for 10-15 minutes. This should dislodge any dried residue that might be in the tip.Has the container been pumped and pressurized. If container is not sufficiently pressurized then will not spray well.If there is anything we can do to help you have a great experience, please don't hesitate to contact our Consumer Services team at 866-324-2647 for assistance. We're here to help!

Worked after a week

The product packaging states, visible results in hours and 10 minute continuous spray time…both statements are LIES. I ended up returning this product after waiting 5 days for results, the spray steam is so weak, it took a very long time to spray the weeds in a 5 foot patch. 3 days after returning the product (8 days after spraying), I saw results…dead weeds but I won't know if it killed the weeds down to the root until next spring. I was treating khaki weed.

reply from Roundup Consumer Services

We're truly sorry to hear that you were disappointed with Roundup Weed & Grass Killer4 Ready-to-Use. We appreciate you taking the time to share your feedback with us.Even though this is a non-selective weed control, some weeds, like weeds with a waxy surface, are more difficult to control. Also, if the weed is mature, no matter what weed, it will be more difficult to control. It is helpful to use any weed control when weeds are young and tender. While weeds will begin to wilt within hours after an application, a complete kill may take 1-2 weeks. Cold or fluctuating temperatures may delay weed control. We want you to feel confident in our products, and your satisfaction is important to us. That's why 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 a refund, with certain limitations applying. Please reach out to us at 866-324-2647 at your earliest convenience if you need further assistance.
