My grandfather used to plant corn, then pole beans next to the corn and allow the beans to climb the corn stalk. I read an article about this, and it also planted squash between plants to keep weeds down and moisture in, it is called a "Three Sister's Garden". Has anybody done this, with or without the squash? I have planted Silver Queen in the past, and I am wondering if the stalks would be strong/tall enough to support the beans.
