Hi Brenda, I would let one of your beans mature until the pod explodes and the seeds are going to drop. Gather and store in a coolish temp, Anyone else have an idea?M

I, too, would leave some beans on your plant until they change colour and mature. An old nylon stocking can be slipped over the bean, so that you don't lose the seed. As suggested, gather and store in a coolish temperature. Don't forget to label. LOL

I saved about 10 different kinds of seeds this year including some blue lake beans. Surprisingly they were my biggest challenge. Those that matured wanted to rot but I did get a few. Wait until the pods turn brown. The pod will hold the seeds. You don't need the stocking.
