"If fall weather is very wet or if frost threatens the harvest, pull plants early and finish drying under cover, such as in a shed, barn or basement. Beans will continue to mature in the pods even after they are picked, so donít worry too much if you have to harvest immature beans. As tender annuals, beans are very sensitive to frost. Plant once youíre sure all danger of frost has passed, and harvest early if needed, as described above, to avoid frost damage in the fall."
Alternately, dry them on the vine if weather allows. I picked them before they were dry and put them in my cellar to dry. I understand, you could also pull the vine and let them dry off it hanging it up side down.
