Most of Michigan's commercial blueberry production is located in southwest Michigan where sandy glacial soils and high water tables result in excellent blueberry soils. These soils are moist with soil pHs in the 4.5 to 5.5 range. Over 20 blueberry varieties are grown in Michigan. The Michigan harvest season normally runs from late June through October.
