Now is the time to prune fruit trees!

Before the buds swell and begin to emerge it is time to prune unwanted branches from your fruit trees. Growers often neglect the annual training and pruning of fruit trees. Without training and pruning, however, fruit trees will not develop proper shape and form. Properly trained and pruned trees will yield high quality fruit much earlier in their lives and live significantly longer.
A primary objective of training and pruning is to develop a strong tree framework that will support fruit production. Improperly trained fruit trees generally have very upright branch angles, which result in serious limb breakage under a heavy fruit load. This significantly reduces the productivity of the tree and may greatly reduce tree life. Another goal of annual training and pruning is to remove dead, diseased, or broken limbs. Proper tree training also opens up the tree canopy to maximize light penetration. For most deciduous tree fruit, flower buds for the current season's crop are formed the previous summer. Light penetration is essential for flower bud development and optimal fruit set, flavor, and quality. Although a mature tree may be growing in full sun, a very dense canopy may not allow enough light to reach 12 to 18 inches inside the canopy. Opening the tree canopy also permits adequate air movement through the tree, which promotes rapid drying to minimize disease infection and allows thorough pesticide penetration. Additionally, a wellshaped fruit tree is aesthetically pleasing, whether in a landscaped yard, garden, or commercial orchard.

General Fruit Tree Pruning Instructions

  1. Always use sharp shears or saws so your cuts are clean. Use pruning shears on young trees and limbs less than 1/2 inch diameter, and lopping shears for your bigger cuts. For mature fruit trees, use a pruning saw.

  2. Begin by removing dead wood and broken branches. Then cut out any wood that crosses or rubs against any other branches. This opens up the middle so the sun can get to all the fruit.

  3. Make your cut close to a bud, to a joint in the branch, or to the trunk; never leave a stub. The pruning cut should be just above a bud. Make the cut at a backwards angle of about 30 degrees.

  4. Prune stems just above a pair of opposing strong shoots or buds. If shoots or buds are staggered, choose a strong one and prune just above it.

  5. Keep more horizontal branches, and prune more vertical branches.

  6. Remove suckers (shoots) from around the base of the tree.

  7. Get rid of all debris which can harbor pests and disease

I'm having a hard time following this step...?

Also when it says remove debris does that mean no mulch?
