Walnuts can be hulled several ways, but the easiest is to mow over them with the lawn tractor breaking the shell but not the nut. Wear gloves when handling black walnuts as the dye they contain is very difficult to remove and will tint anything it touches. Spread the hulled nuts onto the lawn or on a wire mesh and spray with water to wash them. Alternatively, you can soak them in a tub of water. To dry the nuts, spread them out in a cool, shady, dry location for about two weeks. (Cynthia Domenghini)
