OK, bottom line, specifically which kind of corn, which bean, which pumpkin, and spacing too. I've heard about this all my life, with no directions. I planted two beans per corn, and only a few pumpkin, expecting corn on the cob, and fresh snaps for dinner.
I've never seen any thing about how to do it the way the Indians did it. Maybe they just harvested dried corn and beans at season's end, hey?
