I have a clover type ground cover along the fence line on the side of my house. The ground cover comes out about 5 feet from the fence then grass runs from the cover to the house. This makes a nice natural path. My problem is I have a perennial growing out of the GC that makes this GC bed look unkept. I don't know what type of plant it is ,but it doesn't flower. It just sprouts up a plant every 2-3 feet or so. My question, what's the easiest way to get rid of the perennial plants. I know everyone will say, get in there and dig them up, but that will be a lot of work. I pulled some up last year and they just grew back before the summer ended.
