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.
The best indications of ripeness are color, flavor, and picking ease. Fully ripe blueberries are uniformly blue in color, have a good flavor, and separate easily from the plant.
Blueberries can be stored for 1- 2 weeks at a temperature of 32°. Keep in ventilated containers. Wash your berries just before using.
