Expert Reviews

What reviewers liked

On the plus side, RoundUp’s initial performance was great. It killed all the weeds in the area where it was sprayed and left most of the grass dead as well.
10-minute rainproof and guaranteed results in just 3 hours
It is also designed in such a way that it becomes rainproof within just ten minutes.
The material not only kills the existing weeds but also attacks the root and vanishes the unborn seeds.

What reviewers didn't like

In terms of prep, it wasn’t easy working with this concentrate. The bottle isn’t well-designed for pouring, and it got messy — as did the other concentrates. We were glad to be wearing safety gear.
Isn’t effective against poison ivy ad woody bush
Might kill beneficial plants and grasses in vegetable and fruit gardens when not used carefully
It is also a grass killer
