  • Make cuts on branch bard ridge so collar heals over itself. Do not paint or seal cuts. Make proper top cuts. Do not top trees ; control height with variety and rootstocks. Control growth direction; generally, prune to downward facing buds for horizontal limb growth. Prune to buds or branches. Do not leave stubs. Prune roots as you would and should a limb or branch.
  • Dormant Pruning: Do in Jan/Feb apples; at pink tip for stone fruits. Prune to a bud going in the direction you want the limb to go.

    • 68. Winter vs. Summer Pruning• Winter (Dormant) Pruning – Promotes vegetative growth in the spring – Use to train young trees• (Late) Summer and Fall pruning – Reduces food storage in roots and hence reduces tree growth in spring – Use on older, overgrown trees to open and rejuvenate the tree. – Use to establish fruiting spurs
    • 69. Restoring Neglected Fruit Trees
    • 70. Rejuvenating Neglected Trees• Always – Remove dead, diseased, and damaged wood – Remove crossing/rubbing branches – Remove water sprouts at limb junction – Remove suckers at the root junction• Never – Remove more than 20% green wood each year – Never fertilize
