Unlike crops like corn or soybeans, which have to be planted each year to harvest a crop, cranberry beds are not planted that often and one cranberry bed in Wisconsin is said to have been planted over a 140 years ago. The average bed is around 40 years old, as older beds are replanted with better varieties of cranberries. The old soil and cranberry vines are removed before the bed is prepared for the new vines.
