Blueberries are typically grown in humid, northern climates that have winter chills, mild summers and low-pH or acidic soils, conditions that limit their range. But many new varieties are available for lower chill areas, very warm areas, as well as coastal areas. The blueberry now has an enormous range. There are three main types of blueberries — low-bush, high-bush and rabbit-eye — all with fairly specific growing requirements. But thanks to the work of hybridizers, new crosses are much more forgiving.
