      Answer This Question

      Roundup Weed & Grass Killer is a non-selective vegetation killer. It will kill almost any green plant that is actively growing. After applying Roundup Weed and Grass Killer lawns may be planted from seed, sod, sprigs or plugs 7 days after the application. Technically you can replant after 3 days, but waiting 7 days ensures a more complete control of existing weeds.

          Answer This Question

          Pets, such as cats and dogs, should stay out of the treated area until it is thoroughly dry. This is to minimize exposure to the product and also to avoid tracking of the product onto other plants, which could cause damage. Although these animals may eat a small amount of grass, they do not consume enough of the product to cause a health hazard.

            We recently had a freeze and all of the st Augustine has browned. I can clearly see the weeds now. Could I apply this to the lawn in the areas I see crabgrass, clover, or dollar weed?

            1 Answer | 
            Answer This Question

            Roundup Weed & Grass Killer should not be used on dormant lawns. It is very difficult to determine when lawns are truly dormant. May kill desirable grass if it is not truly dormant. If lawn is truly dormant, then weeds are unlikely to be actively growing so would not get the desired weed control.

                  How do I get the lid off of the pump n go in order to refill it?

                  Answer This Question

                  To open the Roundup Weed & Grass Killer Pump N' Go, stabilize container by holding between your feet. While holding the pump handle push down slightly and turn left, the pump will be out of the locked position. The first time it is opened it will be difficult to open because for shipping safety the top is put on very tightly at the factory, also can be more difficult when pressurized especially if fully pressurized. If container is pressurized, you can let it set for a bit and allow the some of pressure to gradually release and then try to open.

                        Kills weeds but wand is wack
                        I bought it at end of season for a good price but the comfort wand does not work properly. The connection between the hose and the comfort wand is not working. I looked on line to see if I could just get a replacement wand but I basically need to buy a new bottle of RoundUp. The product works well but I just need to get it on the weeds.

                          We're sorry to read about your disappointment with Roundup Ready-to-use Weed & Grass Killer III with Pump 'n Go and appreciate your feedback. Potentially, some product has crystallized in the sprayer tip. You can soak the nozzle or sprayer tip in warm water for 15 minutes to dissolve any residue that dried in the tip. If the bottle is almost empty, then likely the siphon tube is not in a good position to get remaining product. You can carefully remove the cap and, with protective disposable gloves on or using a disposable towel, carefully try to adjust the direction of the siphon tube. The Pump should be pumped about 20-30 times to build pressure. Make sure to listen for air leakage. 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 at866-324-2647 if we can further assist.

                              [This review was collected as part of a promotion.] We get the best results from this product and have used it regularly all around our yard. We had some really nice early spring weather and have no signs of weeds 2 months later. It will probably be the middle of summer before we have to spray again. Highly recommend!

                                The product is great, but not the sprayer.
                                I bought one last spring, along with refill fluid concentrate. When I refilled it, the sprayer would no longer hold pressure, so I went back to the store. They looked it over & replaced it. I finally ran out of fluid again, refilled it, and again, no pressure. The store says they replace a lot of them for just this reason, but it’s been too long since I purchased this one - I have to buy a new one. I’m going to try the Ortho brand instead. So, I’m summary: the weed killer works well, just don’t expect the refillable sprayer to actually be refillable! :(

                                  We are sorry to hear that you did not get the results that you expected when using Roundup Weed & Grass Killer. Did it rain or was area watered less than 2 hours after application. We recommend that weeds not be cut for two days both before and after the product application to maximize leaf surface and absorption.

                                  Trying to remove any growth occurring between driveway pavers. It's a very large u shaped driveway and I used the entire container in one application. The "u" or lower "h" shaped paved driveway is at least 70 feet in diameter. On the spray setting as opposed to stream, it didn't spray very far or even. I don't think a battery operated sprayer would have done any better. The weeds and overgrowth seems to be turning brown however it's been raining a lot lately. I am concerned the torrential rains two days after application may have weakened the product efficacy. In hand pumping the tank I also had concern of over pressurizing it. However I saw very little correlation of pressure in relation to spray distance. I did manage to cover all the areas I wanted to kill the weeds. A week later I still see some growth in spots. For only $20.00 I made a repeat purchase for a second application. I may purchase a stand alone sprayer and concentrate formula next if this doesn't work.
