Image taken by Mike Andree. This is an image of several honey bee colonies being used for pollination in a cranberry bog just outside Hammonton, NJ. In general, one strong colony per acre is currently used to pollinate cranberries. Depending on the weather, cranberry blossoms last 10 to 12 days. Pollination occurs when the bee thrusts its head and proboscis or "tongue" into the staminal tube to reach the nectar, the pollen rains down upon the bee. Then when another more advanced flower with a receptive stigma is visited, the pollen is accidentally transferred, and fertilization is accomplished. If the flower is not fertilized, it may hang on for 2 or 3 weeks, and the petals will take on a rosy hue. A key to identification of inadequate pollination is the presence of this pinkish cast in the field. Prompt pollination causes the petals to shed and fruit development to proceed before this can occur. The fruit ripens in a couple of months.(for more info on cranberry pollination visit www.ars.usda.gov Will open in a new tab or window)
Cranberries are primarily grown in five states -- Massachusetts, Wisconsin, New Jersey, Oregon and Washington. Another 5,500 acres are cultivated in Chile, Quebec, and British Columbia. There are nearly 1,000 cranberry growers in America. If all the cranberry bogs in North America were put together, they would comprise an area equal in size to the tiny island of Nantucket, off Massachusetts, approximately 47 square miles.

The cranberry is one of only a handful of fruits native to North America - the Concord grape and blueberry being the others. Contrary to popular belief, cranberries do not grow in water. They are grown on sandy bogs or marshes. Because cranberries float, some bogs are flooded when the fruit is ready for harvesting. If you strung together all the cranberries produced in North America last year, they would stretch from Boston to Los Angeles more than 565 times. The 1996 harvest yielded more than 200 billion cranberries -- about 40 for every man, woman and child on the planet.(for more facts on cranberries be sure to visit www.oceanspray.com Will open in a new tab or window)
