There are three types of blueberries - highbush, lowbush, and rabbiteye. Highbush types are grown in the midwest, northeast, and parts of Canada around the Great Lakes. The lowbush types are grown in the Pacific west states and also in other parts of the nation. Rabbiteye type is grown in the southern states. It can tolerate a wide range of soil pH, high temperatures, and has low chilling requirement. Most of the blueberry roots are distributed with the dripline of the bush. Some roots may extendsix ft away from the crown, and depths of up to 32 inches. Blueberries do well in full sunlight, well drained soil with a pH of 4.5 to 5.2, and adequate moisture. Blueberries are propagated by rooting of hardwood cuttings that are one-year-old. Two to three year-old nursery grown plants are recommended for planting. Use of organic mulches (4-6 inches thick)such as straw, wood chips, saw dust, corn cobs is desirable. Since blueberries are sensitive to chloride, applications of potassium sulfate is recommended, and the ammonium form of nitrogen is preferred compared to nitrate so ammonium sulfate is recommended. Blueberries need to be pruned annually in order to get optimal yield.

Blueberries are pollinated by bees. In large plantings, a beehive is necessary, but in small backyard gardens bumblebees and other wild bees can accomplish the task.
