Let's save some bean seeds! (These steps are the same for peas).
First you want to let your beans dry out on the vine. Wait until they are completely dry and crunchy before harvesting. The beans should be nice and plump.
Once the beans have completely dried you can harvest them.
Then all you have to do , is remove the outer layer and then you will have your beans!
It seriously is that easy!!
Happy seed saving!
