By Melissa Kruse-Peeples, Education Coordinator For many Native American communities, three seeds - corn, beans, and squash represent the most important crops. When planted together, the Three Sisters, work together to help one another thrive and survive. Utilizing the corn, beans, and squash together in your garden draws upon centuries of Native American agricultural traditions and expertise. This post covers the benefits of three sisters planting and provides tips for when to plant, varieties that work well in planting together, and suggested layouts for your garden.

These three crops are also important because they can all be dried and used for food year round. These traits are less important today, but were important in the past which lead to their significance as the major cultivated foods. The tradition of calling these crops the
