                  I've used Roundup Weed & Grass Killer on several areas around my property, including gravel, sidewalks, and landscape beds, and it's consistently delivered good results. It's easy to apply, starts showing visible results within a few days, and does a great job of killing existing weeds down to the root when used as directed. I especially like that it saves a lot of time compared to pulling weeds by hand, and one application typically keeps problem areas under control for quite a while. Just be careful when spraying around desirable plants since it will damage anything green that it contacts. Overall, it's a dependable product that does exactly what it's designed to do. I would definitely purchase it again.

                  Works kind of…
                  I have purchased this several times with very limited results! I have a 3 gallon sprayer, I mix in double the concentration and spray weeds. A week later I’m pulling weeds that are only half dead and the is new growth from the stem. I would attach a video but that link doesn’t work either!

                  We're sorry to hear that you were disappointed with the Roundup Weed & Grass Killer 4 Concentrate.

                  To get the best results, plant leaves must be thoroughly and uniformly covered with the spray solution. Weeds will begin to wilt within hours after application, but a complete kill may take 1-2 weeks. Applications are best made when temperatures are between 60°F and 85°F. This product will not prevent weeds, only kills weeds that are green and growing at time of application.

                  We value your feedback and are eager to learn more about your experience so we can improve. Please contact us at 877-220-3089 at your convenience.

                  We look forward to hearing from you and working towards a better experience. roundup
                    We live next to unmaintained farmland and get lots of weeds. I prefer to buy the RoundUp concentrate. I mix up a batch in a one-gallon pump sprayer make a tour around the yard looking for problems. RoundUp is effective and the results are fast. Weeds are usually dead in a day, although thistles seem to hold out longer.
                    by
                    Product never fails. Kills weeds quickly. I typically use a heavier concentration than directed; however, I am certain the recommended concentration would work perfectly fine. The free sprayer promotion was an added bonus. Even if the sprayer lasts only one or two seasons. Which is typical for me, I’m not out any money.

                    Not bad. 95% effective
                    I needed to kill my entire front lawn which was basically a mix of different types of weed and a Bahia grass. Using a mixture of 6oz for every gallon of water killed 90% of the lawn the first time around in just 7 days. I did end up needing to spot apply a second round of Round up but a few weeds just wouldn’t die so I will need to pull those up manually. So overall 95% effective in my experience.

                      I am not impressed. I always mix double the minimum amount. Most weeds were not affected. I don’t know if it was because it has been cold which may have reduced the effectiveness of the Roundup.

                        I’ve been using RoundUp concentrate for a few years now and it consistently does the job for keeping down the weed growth around and in front of my house. It takes a few days to take full effect, but it always works. (Photo is after spraying and wacking)

                        Our yard consists of mostly large gravel. Roundup has helped maintain and keep the yard weed free. It works great for the landscaping on our property! Your results may vary.
