Thought I'd start a little blog on growing and seed saving beans. Perhaps others might like to try these things and save seeds from their favourite beans. To start with, this is how I make a tripod out of bamboo. Its quite easy to do, its portable, you can pack it up when the seasons over and use it following year.
Plant 4 or so beans around each bamboo pole.
If you plant more than one runner bean they will cross easily, pole or climber beans won't cross. So with seedsaving beans, harvest them when the pods have dried out in fine weather. If you don't dry your beans properly they will turn moldy. Select the best looking specimens to save seed from and eat the rest. Take them inside and lay them in an airy place to further dry out. After a few days shell the beans and leave on a tray or plate for a day or two. Then put them into the freezer flat on a plate for a few days to kill off any bugs. If you've ever had holes in your seed from bean weeviles this is a good way to kill them without using chemicals. Take them out of the freezer and leave them in a warm spot to dry out. Store in paper bags, dated and named.
