Siena Farms

We're a family-farm, in our 17th year of operation, cultivating 75 acres of protected farmland in Sudbury and Sterling, MA. We grow over 100 varieties of vegetables for our year-round CSA, our farm stores in the Boston Public Market and Boston's South End, and select restaurants and chefs.

We grow our produce using regenerative, biological agricultural practices; free of chemical herbicides, pesticides, and synthetic fertilizers. We work to build our fields' soil fertility and microbial activity by using natural composts, certified organic fertilizers, cover crops, and mineral amendments. We have chosen to forgo the USDA's organic certification process for the farm as a whole, but invite you to trust that we, your farmers, grow our produce using ecologically and socially responsible methods, on par with current organic standards.

Choose home delivery or pick up your CSA from one of our 30+ host sites around eastern MA, Cape Cod, the North Shore, and NYC. We offer flexible scheduling, including last minute scheduling changes, and pickup site & home delivery changes. Along with our specialty share add ons, our home delivery courier offers a la carte pantry & dairy add ons. Go to https://sienafarms.com/ to learn more.
