I came back from vaca to find a bed that had never had weeds before ONE FOOT high in SOLID weeds...! I'm trying to weed it, but it's taking ages to do and cover with mulch (Texas hardwood mulch I get at Home Depot). Has anyone ever just pulled most of the weeds and covered the stubs up with thick mulch? I'm almost willing to try that as the bed is 5'wide and about 30 feet long!!
