Gardening - Fruit: Maintenance
Proper pruning practices in blueberries are important to maximize yields and quality throughout the life of the planting. Pruning should be done every year, beginning at the time plants are set. During the early years, the objectives of pruning are to promote both plant survival and growth. Once plants have attained full size, pruning is used to promote fruit yields and quality, as well as to maintain plants within desired size limits.
