Q.Herbicide For Last Of Rhizomes Under Sidewalk?
I have removed bamboo and rhizomes to the best of my ability. A rhizome(s) is still growing under a nearby sidewalk that cannot be removed. What herbicide will kill the little shoots as they emerge at the side of the sidewalk and between the cracks? I’ve tried vinegar and boiling water to avail. Thanks kindly, Kim

An herbicide with glyphosate should work. You might even go for the brush killer herbicide. Be sure to read and follow all label directions.
