Greenwich has been primarily agricultural in nature since being first settled by families including the Bishop and Forsyth families, who settled here in 1760 as New England Planters; both of these families still farm in Greenwich today. The Windsor and Annapolis Railway arrived in 1869. Greenwich served as the station for nearby Port Williams. In 1884, the first apple warehouse in Nova Scotia was built in Greenwich beside the station, quickly followed by many others in the 1890s paving the way for a rapid growth in the apple industry in Nova Scotia. Rail service lasted until 2006 and attracted bulk distributors for feed and fuel.

Greenwich has a population of approximately 300 people. Agriculture remains an important industry but water, sewer, hydrant, street-lights, bus transit and sidewalk services have attracted residential and retail growth within easy access of both New Minas and Wolfville. Greenwich is also served by a volunteer fire department. The community has hosted Horton High School in two different locations since 1959.

In 1906, Andrew R. Cobb designed the plans for a new building to replace the original Methodist meeting house from 1833. The new building was completed in 1910 and the old meeting house was demolished. In 1923 it became the United Church of Greenwich and was part of the United Church of Canada. In 2012, the congregation amalgamated with congregations of several surrounding communities to form the Orchard Valley United Church. The Greenwich church building was sold to Noggins Corner Farm and has been renamed Bishop Hall. It currently functions as a space for community gatherings.

There are five farm markets located on the main road in Greenwich, they include: Elderkin's Farm Market & Cider Company, Stirling Fruit Farms, Hennigar's Farm Market, Noggins Corner Farm and Avery's Farm Market.

Elderkin's Farm Market & Cider Company, located on Broadview Farms - one of the first farms created when Greenwich was settled - has been family owned and operated since 1760.

Stirling Fruit Farms was founded by Alexander Robert Stirling in 1917 when he began farming land that belonged to his aunts when he was seventeen. He opened his first roadside market in Greenwich in the 1940s and it is currently owned and managed by his descendants.

Hennigar's farm was founded in 1921 when Edward and Thelma Hennigar purchased 39 acres of land to farm. Their first farm market was opened in spot called the "Tannery Hollow" by their son Rhodes and his wife Gloria in 1952.

Noggins Corner Farm Market is on the site of original 1760 land grants for Timothy and William Bishop and is run by members of the Bishop family descended from Timothy. The farm market was established by Sandy and Avard Bishop who took over the farm in 1955.
