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.
Please Note: All of our Farm Shares are available for pickup and home delivery throughout Manhattan and Brooklyn, and throughout Eastern MA from Worcester to Boston, the North Shore and Cape Cod. You will be able to make these selections at checkout for all Farm Shares listed below.
Pricing is now the same for NYC and Massachusetts distribution (no extra freight charge to NYC like in past seasons).
