Save 10% on all 2025 CSA Farm Shares through December 15th, 2024!
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.
Seasonal, Year-Round, and Specialty Farm Shares are available, plus our new Monthly CSA Subscriptions. Enroll in a Vegetable or Mushroom Subscription anytime, any season — and start right up next week! Designed for new and returning members, you can now join our CSA one month at a time, with easy monthly payments.
Office and home delivery is available year-round throughout Eastern MA from Worcester to Boston, North Shore and Cape Cod, as well as Manhattan and Brooklyn.
Or, pickup from one of 35+ convenient pickup sites.
Schedule Options: Choose between WEEKLY Shares and FLEX Shares (flexible schedule averaging every other week).
Size Options: Choose between our Classic Vegetable Share (half-bushel box) and our Small Vegetable Share (third-bushel box).
