Heirloom Bean saving
So I know its not completely right to do but my CSA has been having awesome heirloom beans (dragon tongue beans, a yellow variety and a dark purple one). Can I just pick the older beans dry them and save the seeds for next year. (I like to supplement my CSA with my garden veggies... b/c then I can get the things I like when I want them versus waiting for CSA to have enough to feed 200 shares before I get them.
ANy tips are appreciated. Thanks
