There are three varieties of blueberry bushes that grow in Georgia--southern highbush, rabbiteye and northern highbush. Once a blueberry bush is established, it thrives with some sunshine, water and occasional fertilizer. The fruit crop ripens in the summertime. Pruning Georgia blueberries will result in healthier bushes and fewer, but bigger, berries.
Avoid pruning blueberry bushes for the first three years. When blossoms grow in the first and second year, simply remove them with your fingers in order to encourage vigorous growth.
Prune blueberry bushes in the fourth year in mid-March. This is right at the end of the dormant season, and at the beginning of the growing season.
Follow dead and diseased stems and branches to the spot where they meet a healthy branch. Use hand pruners to cut at the joint and remove the damaged stem.
Expect buds for next season's blueberries to form in the late summer to early fall. When you prune the newest buds, you're cutting down on the following year's fruit production.
Remove branches that are in the middle of the Georgia blueberry bush if they cross each other. This is essential to allow air and light to get to the center of the plant.
Control bushy plants by cutting some of the stalks. Place the cut as far down on the stalk as possible, inside the bulk of the bush.
Trim the sides of the Georgia blueberry bush with hedge clippers to make it an acceptable height and width. Run the clippers along the sides of the bush, taking off a little at a time, until you achieve the desired size.
