The Crimson Harvest
Every fall in parts of Massachusetts as the leaves change from green to orange, red and yellow, the annual cranberry harvests begin. Millions of the marble sized berries are either combed from vines in dry harvesting or thrashed from vines by a paddlewheel in flooded bogs.
Cranberries are native to North America and southeastern Massachusetts is considered to be the birthplace of the commercial industry that contributes over $1.7 billion to the Commonwealth's economy yearly. There is nearly 12,000 acres of cranberry bogs in Massachusetts, and many of the farms offer public tours on Saturday mornings in the month of October.
Here on Gate Cranberry Company Bogs in Rochester, 'wet harvesting' takes place; the process of flooding a bog with water, causing the vines laden with fruit to float to the surface. A crew member then pilots a specialized tractor, called a water wheel, that thrashes or slaps the vines on the surface to dislodge the cranberries.
After the vines are thrashed, crews use long booms to corral the cranberries to one location of the flooded bog, while wearing waders in the cold water. The berries are then pumped from the bog with a large water vacuum process, and then loaded into large tractor hopper trucks to be taken to a processing plant.
After harvest, the bogs are dormant and growers start their off-season maintenance of cleaning, pruning the vines and bog repairs.
