C.S.A.
Community Supported Agriculture (CSA) is a collaboration between farmers and their customers. When you purchase a CSA membership, you support our 50-acre farm through the inherent risks, and delicious rewards, of farming in New England. In return, you share in our harvest with a weekly box — a Farm Share — of fresh produce from our farm.
