Used product to kill the weeds on my sidewalk accidentally got some on the grass with in a few hours the weed on sidewalk went from green to brown and my grass was beguinning to turn as well. With in a few days the side walk is clear and I have a patch of mud :(
I bought two 1.33 gals of this Roundup weed and grass killer but grass still keeps growing. There's the plastic cover over the ground and overlayed gravel over the plastic and irrigation was totally plugged.
This product comes in a container that also doubles as a sprayer. If you follow the directions, this will eradicate unwanted weeds remarkably well. I like this product and would recommend it highly.
