The cranberry harvest in New England takes place during October. The harvest itself appears to be a visual treat.Cranberries are harvested in various states throughout the United States. Wisconsin is the biggest cranberry supplier, but Massachusetts, Maine, and neighboring states in Canada like Nova Scotia, Québec and New Brunswick have a fair amount of cranberry growers too.It takes a year for a crop of cranberries to be ready. Ninety percent of the time, the bog remains dry. Then, by mi-September each year, when the cranberries are ripe, the bog is flooded, ready for harvesting. The harvest will then last until about the end of October. It’s a cycle that repeats every year, with crops better some years than others.
