[header] How to grow lima beans [title] Acquire lima bean seeds. [step] There are two main varieties: bush beans and vine (pole) beans. They are often labeled determinate and indeterminate, respectively. <sep> (A) [substeps] Bush beans usually have well defined roots, while vine beans have distinct grooves along the bottom which are called direction lines. Vines grow from the bottom to the top of the plant, where they tie the plant together. (B) [substeps] Bush beans grow in hardiness zones 1-16. Shoot but don't live too deeply into hardiness zones 9-13. (C) Lima beans are annuals, which means that they grow within a single season once a year. Find lima bean seeds at a local nursery or garden-supply store. (D) Bush beans grow the fastest and easier than vine beans. This means when digging up your seeds, you can see if they are growing to the size of bush beans (small but large enough to fit comfortably inside a larger pod).
