A fledgling farmers’ market in West Bridgewater will be operating for three days this season. Run by the First Church of West Bridgewater and the town’s Agricultural Commission, the market was held on a single day last August on a trial basis. Because of the positive response, organizers decided to expand the pilot initiative this year to June 24, July 22, and Aug. 19. The market will operate from 9 a.m. to 1 p.m. on those days on the grounds of the church, 29 Howard St. To date, nine vendors have signed up to sell goods ranging from fresh produce and eggs to honey, herbs, flowers, bottled water, and firewood, according to June Metcalf, a commission member, a vendor, and a parishioner at the First Church. As a complement to the market, the church is inviting the public to a pancake breakfast from 8 to 10 a.m. on each of the three market days, according to Metcalf, who credits the church’s pastor, the Rev. Carol Ashton, with spearheading the market initiative.
