terminal role. It opens the tree, reduces weight, reduces height, and retains its
shape.
Discuss Shingo's theory of walling off infections in trees called CODIT
(Compartmentalization of Decay in Trees). - Correct Answer-1) Trees are highly
compartmentalized.
2) If the tree is wounded, it will heal itself by walling itself off from injury.
How will pruning a tree at time of transplanting affect tree growth? - Correct
Answer-It decreases root growth. You should avoid pruning except for broken or
damaged limbs.
Are there advantages of pruning a tree at planting time? - Correct Answer-No
What is the major objective in crown cleaning? - Correct Answer-It removes dead,
diseased, and dying crowded or wealdy attached limbs from the crown. the
objective is to correct small growth problems before they get big growth
problems.
Name five methods used to apply fertilization to trees. - Correct Answer-
Broadcasting, drill hole, injection, foliar application, and implants
Are wound dressings or paint recommended after making pruning cuts? Why? -
Correct Answer-No, studies show it does no good.
