Three Sisters (crop planting technique)

The Three Sisters is a traditional Native American agricultural technique that involves planting three complementary crops together: corn, beans, and squash. Corn provides sturdy stalks for the beans to climb, reducing the need for stakes. Beans enrich the soil by fixing nitrogen, benefiting all three plants. Squash's large leaves shade the ground, suppressing weeds and retaining moisture. This method enhances yield, promotes biodiversity, and creates a self-sustaining ecosystem, reflecting the interconnectedness of nature and traditional farming wisdom. It exemplifies sustainable agriculture and was foundational in the diets of many Indigenous cultures in North America.
