The cranberry plant is native to large portions of the northeastern United States as well as the West Coast states and portions of Canada. Cranberry production requires a rather unique acid bog habitat, which restricts its commercial production to just a few states. Wisconsin, Massachusetts, New Jersey, Oregon, and Washington are the leading producers in the US.
The ideal soil pH is 4.0-5.5, quite acidic compared to other horticultural crops. A large supply of fresh water and sand is also required.
