Blueberries are native to the Eastern United States.
Blueberries flourish in areas of the world that meet its specific soil and climate requirements. The plants MUST have acidic soil and will not grow or produce well in alkaline soils. Optimum quality results in areas of the world with cool summers and acidic soils - the Northwest coastal regions of the United States, Northern California, and British Columbia, to name a few. Blueberries also grow well in Michigan, New Jersey, and to a lesser extent in New York, Massachusetts, and Indiana.
Even when planted in an acidic soilless mixture in containers, alkaline elements found in some water sources will damage the plants by neutralizing the soil pH.
Blueberries are related to huckleberries, rhododendrons, and azaleas. These plants also thrive in environments similar to the ideal blueberry environment.
Blueberries are long-lived shrubs, growing 7 to 8 feet high and spreading up to 8 feet. They require about three to four years before they will begin to bear fruit. They are about as winter-hardy as peaches, but require a winter chill and do not produce well in areas with mild winters.
