Blueberries thrive in acidic, well-draining, weed-free soil. Choose a location with full sun, and use an irrigation system to keep the root zone moist throughout the growing season. To prepare the soil, dig up an area that is 2 1/2 feet in diameter and 1 foot deep, and replace approximately one-third of the soil with peat moss. Work the peat moss evenly into the soil before planting the blueberries 2 1/2 to 3 feet apart to form a hedgerow.
To space blueberries, rather than growing the plants in a hedgerow, plant the bushes approximately 6 feet apart. Space rows 8 to 10 feet apart, and cover the roots with a 2 to 4 inch layer of mulch. When growing blueberries in raised beds, use equal amounts of peat moss and tree bark as the growing medium. Do not use cedar or redwood mulch on blueberry plants.
When transplanting blueberry bushes from a container, shake the excess dirt from the root ball, and pile the dirt over the root ball in a mound that is 1/2 inch above the surrounding soil.
Prune well-established blueberry plants heavily to encourage healthy fruit production, and cut away dead or diseased areas as needed. To prune young plants, cut away dead or diseased areas, and remove a large portion of the blooms to ensure healthy, tasty berries. Fertilize blueberries at the beginning and end of spring. Water the plants thoroughly after fertilizing, and do not overfertilize.
