This is my first year growing any type of bean. I planted 4 rows of dry bush beans. Jacob's Cattle, Calypso, Adzuki, and a Black Bean. I'm letting all of them dry on the vine before picking them to shell out and finnish drying inside. Jacob's Cattle did great. I'm freezing them now before I store them. I've picked some of the black beans and adzuki and they seem fine too. the problem is the Calypso beans. They're a black and white bean and all the pods i've picked off the vine are shriveled up and the beans inside seem flat. Did I leave them on the vine too long? Is that possible to do? Why would they all be shriveled up? Should I pick them when the pods are still green and full and let them dry inside. I thought you were supposed to let them get brown and hard and dry on the vine, but these are brown and leathery and just plain withered up. Anyone know what I did or didn't do?
