How long does it take for bleach to kill grass?
Pour undiluted bleach over the grass. For most soil conditions, only about 1 cup of bleach is necessary to kill grass over a 6-by-6 inch square area. For soil with lots of clay, use about 2 cups of bleach. Wait one to three days and when the grass turns brown and is dry, pull it up to remove.
