The “Three Sisters” Were a Genius Farming System 🌽 Corn, 🫘 beans, and 🎃 squash were planted together. Each supported the others: corn gave structure, beans added nitrogen, squash blocked weeds.

Indigenous Peoples Domesticated Corn Over 9,000 Years Ago Maize was first developed from wild grass (teosinte) in Mexico. It became the most influential crop in the Americas.

Native Farmers Practiced Polyculture, Not Monoculture Unlike modern single-crop farming, they grew multiple plants together to enrich soil and prevent pests — a sustainable model.

Terraced Farming Was Used in Mountain Regions Tribes in the Southwest, like the Ancestral Puebloans, created stone terraces to conserve water and soil on dry, steep lands.

Biochar Was an Early Soil Fertilizer Some Indigenous groups mixed charcoal, bone, and compost to enrich soil — a technique now known as Terra Preta.

Chinampas: Floating Gardens of the Aztecs While in Mesoamerica (not modern USA), these man-made agricultural islands inspired water management ideas in North America.

Sunflowers Were Domesticated in Eastern North America Used for oil, seeds, and medicine — long before it became a snack or crop in the modern world.

Indigenous People Managed Forests for Edible Plants Native Americans used controlled burns to grow crops like wild berries, nuts, and root vegetables — an early form of forest agriculture.

Irrigation Systems Were Engineered in the Desert Hohokam people (in present-day Arizona) built hundreds of miles of canals for farming in arid regions — before European contact.

Tobacco Was a Sacred & Cultivated Crop More than just a plant, tobacco was grown and used ceremonially, making it one of the earliest cultivated cash crops.
