In the spring and early summer, a blueberry shrub will blossom and produce fruit, which will be harvested between June and August. A blueberry bush will begin to bear fruit two to three years after planting, attaining maximum output after six years and reaching full size after eight to ten years of cultivation.
Where do blueberry bushes grow best?
Plant hardiness zones 3 through 8 of the United States Department of Agriculture are the best for growing blueberry bushes. Prior to bearing fruit, a blueberry bush must be at least two or three years old and well-established in order to produce fruit.
