It worked great!

[This review was collected as part of a promotion.] This is my first time using Roundup Weed and Grass Killer. We bought our home two years ago, and this year, I have decided that I am ready to tackle the flower beds. One on the side of the house, I have decided to turn into a little gnome garden. The previous owners have some plants planted that last year I pulled and thought I got rid of, but no, they came back. That is where the Roundup came in. I made sure to read the instructions fully. I also used disposable gloves to make sure I didn't get it on my skin in case the bottle leaked (which it did not). I think having it in a spray bottle made it super easy to get sprayed exactly where I wanted it. I waited about 5 days after the first time I sprayed, and well over half of what I wanted taken care of was so I sprayed one more time and now it is all gone. I have a super clean area for my gnome garden. So far, I have to say I do not see any negatives. It is super easy to use even for novices like myself. It absolutely does the job that it says it will and I could not be more pleased.

Great weed killer

[This review was collected as part of a promotion.] This works fast!! I sprayed some weeds in my walk way and a few days later they were dead. It is very effective and I am very satisfied with the results. It comes in an easy use spray bottle with a nozzle. You just have to be careful with weeds on your lawn because it is also a grass killer. I wouldn't suggest using it there. It's great for mulch beds, driveway, walkways… pretty much anywhere there is not grass!
