Season 2024 CSA Farm Shares now available!
Community Supported Agriculture (CSA) is a collaboration between farmers and their customers. When you purchase a CSA membership, you support our 75-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 brand new Monthly CSA Subscription. 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 30+ 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).
Autumn Farm Dinner
Please join Chef Ana and Farmer Chris in the fields this autumn for our 4th annual farm dinner and fundraiser to support our Community Sponsored Farm Share program, which provides Siena Farms' produce to local families facing food insecurity.
The event will take place in the heart of our fields and greenhouses, and feature live brass music, an open bar, and a very special team of chefs preparing an elaborate feast for the evening.
