I found this last night, it seems to be a good idea!
Many Native North Americans used a system of farming that is commonly know as the 3 Sisters. It uses 3 important food plants together, corn, pole beans, and squash, to support each other and produce more food than each would on their own. The tall, strong corn stalk provides support for the twining pole bean, the pole bean fixes nitrogen in the soil that can be used by the other two plants, and the squash provides ground cover to keep moisture in the soil and keep weeds out.
So, with the final threat of frost past here in the North lands and the planting season upon us, my idea this time is a new version of the 3 Sisters.
