The three sisters agricultural system is a traditional Native American farming method that involves planting three complementary crops—corn, beans, and squash—together in a way that maximizes space and enhances growth. This system exemplifies sustainable agriculture by leveraging the natural benefits of each plant, where corn provides a structure for the beans to climb, beans fix nitrogen in the soil to nourish the corn, and squash spreads out to suppress weeds and retain moisture.
