Can bleach kill grass

ANSWER YES. Bleach is safe to use to kill weeds if you: 1. are careful not to get the bleach on lawns, flowers, or other plants (it kills them, too) 2. wear gloves and safety goggles when handling large amounts of bleach 3. keep all children and pets away from the bleached area for at least an hour. The longer the better. ANSWER Actually, many weeds are annuals, and by weedwacking them, they will not produce seed and may die on their own. Others you can dig up and will not have issues with chemical residue in your yard. You can use other chemicals that you spray on the leaves, which will kill them within a few days.
