Pulling weeds is hard, backbreaking work. It's tough on your hands, and your knees. That's what makes Ortho GroundClear so amazing. One application kills weeds for up to one year, with no digging, pulling or yanking required.
Designed for hardscapes, GroundClear does exactly what it says: it clears the ground of weeds for up to one full year after a single application. Boom!
