The gentleman who came to rid my back path of many weeds was very polite and nice. He sprayed the entire area which included a lot of rocks. But the weeds are still there!!!! I tried to pull some out, but they were deep in the ground. Does Truly Nolen use anything besides spray to get rid of weeds? I wanted the small pathway to be clear to make it easier for those who walk it. Adrienne Drell, 6442 N. Desert Wind Circle.
