What was the ''three sisters'' planting concept?

Beans, Corn, and, Squash

Explanation:

The corn would grow tall so the beans could wrap around the stem, the squash would grow at the bottom. The Three Sisters method is companion planting at its best, with three plants growing symbiotically to deter weeds and pests, enrich the soil, and support each other.
