Beans: Beans such as string beans are exceptionally easy to grow. They take up little space and are very productive. You can choose between growing bush beans or climbing beans. Bush beans grow to knee height and will benefit from something to hold on to or lean against, whereas a trellis or tall stake framework will be required for the climbing beans. Tip: beans can be blanched and frozen for later use, used in fresh salads, hearty stews and soups, or pickled as a tasty treat
