Individual fruit size is increased by pruning. First year plants should have all weak and spindly growth pruned out and flower buds removed to prevent fruiting. This can be done by pinching back the shoots bearing flower buds just below the buds or removing individual flower buds.
Should I pinching off blueberry flowers?
Unlike edibles that are planted and harvested in one season, blueberry bushes require more time to establish before producing a strong harvest. To grow a high-yield blueberry shrub, pinch the blossoms the first two years. Pinching the blooms gives the plant time to establish itself and mature.
