Three Sisters Farming is an agricultural practice used by Native American tribes, particularly in the northeastern and southeastern regions of North America, where three main crops—corn, beans, and squash—are grown together in a symbiotic relationship. This method not only maximizes agricultural yield but also promotes sustainability, as each crop supports the others' growth through a unique interdependence. Corn provides a structure for the beans to climb, beans enrich the soil with nitrogen, and squash leaves shade the ground to retain moisture and suppress weeds.
