New to the forum and have a question. I have a commercial facility that has large parking lots with lots of cracks and, of course, crack weeds. I am tired of using man hours spraying and grinding from March until November. Has anyone here applied Sahara, Mojave, Pramitol, or any other bare-ground herbicide to parking lot cracks to control them? If so, had any problems killing turf or trees/shrubs near curb edges? I could still use it away from bed and turf edges if there's a problem killing desirable plants. Any experiences are greatly appreciated. Thanks!
