What would be a good planting site for blueberries?
Blueberry plants require a sunny location and a well-drained soil high in organic matter. Avoid wet, poorly drained sites. Blueberries are susceptible to root rots in poorly drained soils. Soil pH is also important. Blueberries require acid soils with a pH of 4.0 to 5.5. Since the pH of most Iowa soils is above this range, the soil pH must be lowered to successfully grow blueberries. Home gardeners can lower their soil pH by adding sphagnum peat moss to the soil. Sulfur can also be used to acidify the soil. Sulfur should be incorporated into the soil a year before planting as it reacts slowly with the soil. Aluminum sulfate should not be used to acidify the soil as large amounts of this material can be toxic to blueberry plants.
