Cranberries have pockets of air inside the fruit. Because of this, cranberries float in water, and thus, the bogs can be flooded to aid in removal of fruit from the vines. … More than 90% of the crop is wet harvested.
A typical cranberry harvest begins in early September and lasts through fall. The cranberry bogs are flooded when the berries ripen. Then the berries are beaten mechanically from the vines. Cranberries float to the surface, where they are skimmed, collected on trucks, and taken for processing.
At the end of September, the berries have ripened enough and harvesting cranberries begins. There are two methods of harvesting cranberries: dry harvesting and wet harvesting.
After harvest, bogs are drained, raked, and reflooded. Water protects the shallow-rooted cranberry vines from frost during the cold winter months. It also protects highly flammable bogs from fire and kills the larvae of potential insect pests.
To dry harvest cranberries, growers use a mechanical picker that looks like a giant lawnmower. The picker combs the berries off the vine with moving metal teeth, and then a conveyor belt carries the berries to a receptacle at the back of the machine. … These cranberries are most often used for cooking and baking.
Narrator: Headquartered in Lakeville, Massachusetts, Ocean Spray harvests 220 billion cranberries a year. Cranberries are primarily harvested in the water. Kellyanne Dignan: Despite what people think, they don’t grow in water all year. Narrator: Cranberries begin as vines in wetland fields called a bog.
Ocean Spray is an American agricultural cooperative of growers of cranberries and grapefruit headquartered in Plymouth County, Massachusetts.
Cranberries grow in beds layered with sand, peat and gravel. These beds are commonly known as bogs or marshes and were originally formed as a result of glacial deposits. … These kettle holes were filled with water and organic matter which created the ideal environment for cranberries.
Cranberries grow in tight clusters, and are either dry picked or wet harvested. Dry picking is most common when the fruit will remain fresh, while wet-harvested cranberries are usually used for juice, sweetened dried cranberries, or when added to other products.
Flooding is so important in cranberry cultivation that bogs where flooding is not possible are no longer considered profitable. Cranberry growers use flooding as a management tool to protect the plants from the cold, drying winds of winter, to harvest and remove fallen leaves and to control pests.
Cranberries have four air pockets inside them, which allows them to float to the surface during the wet harvest operation.
Before being harvested and sold, an individual cranberry must be able to bounce at least four inches high to make sure it is not too ripe. Contrary to popular belief, cranberries do not grow in water. They actually grow on vines like a groundcover in impermeable beds layered with sand, peat, gravel, and clay.
Cranberries are perennial, and once planted they’ll keep producing crops year after year even with minimal care. Our small 8×8 cranberry bed produces enough to keep our family supplied all winter long, and all it takes is occasional weeding and sand mulch once per year.
The Ocean Spray cooperative was formed in 1930 to centralize marketing of cranberries and cranberry products. The company develops and markets products and devises better ways to grow and harvest their growers’ crops.
Because cranberries contain pockets of air, the freed berries float to the surface of the water. … The berries are then collected using giant nets by producers who wear waders then transported by trucks to a central unit, where they are sorted and graded.
Cranberry plants generally grow in the period between the last spring frost, and the first autumn frost. That might sound like the berries should thrive during the summer, and they do, but extremes in temperature (like the ones we experience during a Philippine summer) dry out their shallow roots, and kill them.
Wisconsin is the leading producer of cranberries, producing 62 percent of the U.S crop in 2017. Other leading cranberry producing states include Massachusetts, New Jersey, Oregon, and Washington.
Eating raw cranberries is safe and easy, though their sharp, bitter flavor isn’t for everyone. Be sure to clean and sort them thoroughly. You should also consume them in moderation, especially when juiced, as excessive amounts of juice may cause stomach upset or interfere with medications like warfarin.
Dry harvesting uses walk-behind machines to comb the berries off the vines into burlap bags. Berries are then removed from the bogs by either bog vehicles or helicopters. … Dry harvested cranberries are used to supply the fresh fruit market. These cranberries are most often used for cooking and baking.
Just five states grow almost all of the country’s supply of the tart berries: Wisconsin produces more than half of all cranberries in the United States, Massachusetts harvests another third, and New Jersey, Oregon, and Washington produce much of the rest.
American highbush cranberry has light reddish brown coloring on young twigs that becomes scaly and gray over time. Its buds are large and reddish in color. Leaf color changes from green in spring to bright red in autumn. The leaves are opposite, simple, have three lobes and have coarsely serrated edges.
Dry harvesting produces fresh, whole cranberries. … Growers use a simple test to see if a cranberry is ripe or not. They drop the berries and let them bounce over a wooden barrier. Air pockets in the cranberries make them bounce, so if the berry is damaged it won’t bounce over the barrier.
Sanding is the most commonly used cultural practice in cranberry production in Massachusetts. Growers apply a thin (1/2 to 2 inch) layer of sand on the surface of producing cranberry bogs at 2 to 5 year intervals in order to promote growth, improve productivity, suppress disease, and reduce insect populations.
In mid-July, petals fall from the flowers leaving tiny green nodes which, after weeks of summer sun, become red, ripe cranberries. Cranberries are typically harvested in October. We flood the bogs with water, then use water reel harvesting machines that loosen the cranberries from the vine.
They are available fresh, frozen, canned, dried and as juices. They are found in different places in the grocery store. Discuss with students the five forms in which cranberries can be eaten: dried, fresh, canned (cranberry sauce), juice, and frozen.
