The objectives of tree pruning are to: 1) remove any damaged or diseased growth, 2) maintain a new supply of limbs that are of optimal fruit-bearing age and placement, and 3) keep the tree shaped according to the form that was desired in the initial training. A better approach is to train a tree into a conical, or Christmas tree, shape where the top of the tree is narrow compared to the bottom of the tree. Traditional training approaches for apples in Utah create an umbrella shaped tree that produces copious numbers of upright shoots in the tops of trees that must be removed each year. Training begins when a tree is planted and continues throughout the life of the tree. The objectives of tree training are to: 1) develop a structure that will support the weight of the fruit, 2) create a balance between vegetative growth and fruit growth, and 3) prevent the top of the tree from shading the bottom of the tree. However, training and pruning cannot overcome poor genetics and improper matching of scion and rootstock. Careful attention to training and pruning in the early years of the tree will establish the correct form and make caring for it in maturity much more manageable. The rewards of proper training are a tree that is easy to harvest, has sustained high yields, and quality fruit. Training and pruning are critical parts of growing a productive apple tree.
