This lesson makes a connection between how both plants and people live in community. On the farm, plants and other organisms are giving and receiving help from one another all of the time. This is reciprocity. Companion planting is the technique of sowing two crops together for a specific purpose, often pest control, space use or yield maximization. Native Americans have been planting the Three Sisters (corn, beans and squash) in one plot for generations. Not only does this trio help each other grow and use nutrients efficiently, but they have higher yields when planted together, and form a nutritious diet. People also need each other: to learn, to pray and to live a spiritual life. When we work in chevruta (learning partners) or are part of a minyan (prayer group), everyone involved can benefit from the group. We are individuals, but our communities are greater than the sum of their parts.
