Growing pole beans with corn in small corn patches at least is a bad idea. The problem is the beans vines entangle the corn which is the whole ides but if wind or rain or even heavy watering occurs and one stalk of corn starts to fall over it takes the whole row with it. Also, if the bean vines jumped rows, adjacent rows will fall too. It's a trick of the devil to think you can get away with not having to build trellis platforms for beans and laziness always prevails. But after losing a corn crop and cursing too, you'll never try this stupid suggestion again. Just plant your corn in one spot and your pole beans somewhere else and all will be happy including you.
