This is a traditional Native American method for growing food in a resourceful way, one that’s been used for many hundreds of years and is based on the idea that each type of plant has something vital to offer the others: The corn grows tall and creates a natural pole for the bean plants to climb. The beans provide nitrogen, a nutrient that helps the other plants grow more efficiently, and the squash stays low to the ground, its large, spreading leaves helping to block weeds and keep the soil moist.
