As far as growing, I soak all my beans before chitting and potting up, I generally get a very high germination rate. IMHO I like to give them a really good start which also means the plants are less likely to succumb to slug damage. The wife objects to windowsills full of plants but that's a small price to pay... ;D I planted them out in an area which had been heavily composted last year as like all beans, they like a moisture retentive home to grow in. These beans are for storage so leave them on the vine until the whole thing withers away. I love the sound of the dried pods rattling in the wind at the end of Summer, reminds me of times in Greece.. ;D Obviously there is the issue of rain and damp in the Autumn but as long as you pick and pod on a dry day then spread out on newspaper to dry before storing in jars.
