Inspect the tree for damage and disease. Mark affected branches with fluorescent tape.
Remove damaged and diseased branches with a pole saw. Use an orchard ladder to reach high areas. After cutting diseased branches, sterilize your saw with a rag soaked in rubbing alcohol. Immediately put the diseased branches into a garbage bag. Do not let them touch the grass or other plants.
If your tree has tangled or crossed branches, remove the weakest in each pair with pruning shears or a hand saw. Dry, cracked bark is a major indicator of weakness.
Shape the tree and prevent overgrowth by trimming some of the new buds.
Taper the top of the tree so that it is significantly narrower than the lowest branches.
When you are satisfied with the tree's appearance, clean all of your cutting equipment with a rag dipped in rubbing alcohol.
