Why America’s Strangest Crop Has to Be Flooded Every Year — Inside Wisconsin’s Cranberry Harvest

#cranberries #wisconsin #agriculture Wisconsin grows about six of every ten cranberries in America. And the vines it grows them on stand in dry ground. So why does a farmer flood the whole field? Cranberries don't grow in water. They grow on low, perennial vines in sandy, acidic soil, and the water comes later: to protect the plants from frost and winter, and to bring the harvest to the surface. Berries are built to float, and a machine called a water reel shakes them off the vines so the field becomes a red lake that can be gathered and pumped to a truck. About twelve minutes on how Wisconsin became America's cranberry state: how a cranberry bed is built, why the berries float, how the harvest works with a water reel, booms and a conveyor, the difference between wet and dry harvest, what happens at the receiving station, how growers manage water through the year, how they protect vines through winter, and why 2025 was a hard year. Every number comes from a public source, and where a figure is my own calculation rather than a published measurement, the video says so.
