Creating a Three Sisters Garden

From http://www.kidsgardening.com/ -

"In a three sisters planting, the three partners benefit one another. Corn provides support for beans. Beans, like other legumes, have bacteria living on their roots that help them absorb nitrogen from the air and convert it to a form that plants can use. (Corn, which requires a lot of nitrogen to grow, benefits most.) The large, prickly squash leaves shade the soil, preventing weed growth, and deter animal pests. The three sisters also complement each other nutritionally."

I would love to try this in our garden. Here is a link to directions, and the title of this post is a link to another resource.
