Blueberries need acidic soil with a pH between 4.5 and 5.0 for best results. Soil pH can be determined with a basic soil pH test obtainable from your local county extension office.
Blueberries need plenty of organic matter, which can be added to the soil by mixing in peat, straw or other organic mulch. Organic matter increases soil fertility and soil properties.
Well-drained soils with a water table approximately 14 to 22 inches below the surface are ideal for blueberries. Blueberries need a constant water supply but will not tolerate standing water or soggy soils.
