Blueberries prefer acid soils. A soil pH of 4.8 or a range of 4.5 to 5.5 is considered optimal. The soil texture that is most common here in western Michigan is sandy loam. In general, lighter textured soils; sands, loamy sands and sandy loams have lower buffer capacity in the soil and tend to lower soil pHs under wet conditions. It is also easier to change the pH of light textured soil. Heavier soils, loams and clays with large amounts of silt and clay have high buffering capacities and change pH slowly and are not generally good blueberry soils because it takes a long time to change the soil pH and it is not cheap to do so. Organic or muck soils are common but the soil pH is still important. If you are looking for a commercial planting site I would not consider any site with a pH above 6. For a backyard planting I would amend the soil by mixing peat moss into the hole half and half with the native soil. Do not use compost in the hole as this tends to raise the soil pH.
