Place the beans in a plastic bag in the bottom of the refrigerator. The crisper drawer in your refrigerator is the ideal spot for green beans. Store the beans for up to three days in the refrigerator, and wash them before using. If you realize you will not be using the beans within three days, store them by freezing them or canning them. Wash green beans in cool water and cut off ends. Cut the green beans into your desired length.
