The field crew finished pruning the blueberries. The best time to prune is in late winter to early spring before new growth. Pruning Blueberries is 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. Early years, the object of pruning is to promote growth. Once plants are established pruning is used to increase fruit yield and quality, in addition to maintaining desired plant size. The type and amount of pruning depends on the type, size and age of the bush. Always remove dead, diseased or damaged canes first. Prune out weak, low growing shoots and then selectively remove older canes to promote new cane growth and to allow light penetration. It is important to have a balance of newer and older canes.
