What is Polycropping?
Polycropping is an Indigenous regenerative agriculture practice where complementary plants are grown together to create strategic allyship. This method models a thriving, interconnected ecosystem in which each plant contributes to the wellbeing of the others. The growing of corn, green beans, and squash together — called the Three Sisters — is one well-known example.
