As the garden is dying down and preparing for winter, I've been out collecting my open pollinated bean seeds to plant in following years, and wanted to share this easy tutorial.
As with all seed saving, be sure that you are only collecting seeds from plants that have been grown from open-pollinated (heirloom) varieties. Any plant that is not open-pollinated, or hybrid, will not produce seed true to the parent type. If you are unsure, check the seed packaging. Most hybrid seeds are not labelled, but most open-pollinated seeds are.
Bean flowers are perfect, meaning that they self pollinate and produce without the help of bees. This makes them one of the easiest seeds to save, because you do not need to worry about cross contamination or hand pollination. The only thing you need to do is allow the beans to grow to full size, dry out, and harvest.
Most green beans are picked while young and tender, when the seeds are very small. If you are planning on harvesting seeds, you will need to allow them to grow until the seeds are fully developed. At this point the beans are not good for eating; they become tough and stringy. Once they have reached this point, simply allow the pod to dry out, and you can harvest the seeds. Here's how:
