Killing weeds with bleach (Sodium hypochlorite) also kills the roots. Spray the weed with undiluted bleach and wait two days. The plant will have turned brown and the roots will have died. Pull the plant up and dispose of it. If the bleach gets on the grass or on a wanted plant, immediately wash it off with water.
