If your driveway is plagued with grass, weeds, dandelions, and such that are an eyesore, you can get rid of them without any pesticides. Sprinkle a generous amount of baking soda (you can even buy this at the Dollar Store) into all the cracks and crevices where the nuisances grow.. Pour water on top. The sodium in the baking soda will draw out the water from the weeds that will prevent their growth. Be careful to avoid any greenery you don’t want to kill!
