anybody use antifreeze to kill unwanted grass and weeds. google says it will kill grass and weeds, as does my neighbor. thought i might try some on the grass in the sidewalk tracks, unless someone has a horror story.
I use that for volunteer trees. Cut the tree off and paint the end of the stump with a foam brush. It kills the root.I use Brush Cutter from the farm store. It'll kill any plant it touches.
