The common bean originated in the Andes. Foundation of Native American agriculture and part of the Three Sister guild: corn, beans and squash. Beans are legumes and fix nitrogen into the soil. Leaf is occasionally used as a leaf vegetable. Regarding seed born bean disease, soak seeds in 20 percent bleach solution for 15-30 minutes and dry before planting to kill exterior pathogens. Dry seed enough to shatter when banged with a hammer, then freeze for three days to kill weevil eggs. Delicious bean recipes.
