well i used the roundup on the gh floor, and killed all the wild and rampant weeds...first i pulled what i could, then roundup heavily on the remainder....i will take gins advice and start a regime of preen, as those little black seeds from that horrible oxalis were everywhere!
before i bring in the underbench plants, i will wait two weeks and roundup one more time, that should get the tough survivors....i thot i loved my gravel floor, but this weed epidemic has changed my mind!
