Round Up Ready To Use, Weed And Grass Killer! By daniellew79 on - Updated Oct 15, 2011
I bought the Round Up, Ready to Use Plus, Weed and Grass killer this weekend. I bought it because we have tons of weeds and grass growing in between our patio stones (pavers). It states you can see results in 6 hours and that is true. I used it around 9am Saturday and by 5pm Saturday I could see a huge change in the weeds and grass growing in between the stones. They were already turning brown and dying. By Sunday morning I was able to rip out all the weeds by the roots and you could see that the Round Up had killed the weeds down to the roots because the roots were all brown and dried up as well. It also states on the bottle that it dries within 20 minutes and even if it rains it will still be effective. I didn't have a chance to test that out because it didn't rain here this weekend.

It works-I use it every year to keep my concrete driveway and front areas weed free. I don't recommend using Round Up for anything but spot weed control. Not big areas.; A tiller and pre-emergent are the best ways to deal with these. You can also smother weeds by placing squares of rubber backed carpet, rubber side down over weedy areas.
I like the part about being rain proof. I don't spray very many things, but it seems like every time I do it rains!
