Major Deadwood Removal
Major deadwood refers to branches that are 1/4″ (dime-sized) or more in diameter, unless specified. Occasionally, depending on the situation, I may consider major deadwood to be 1/2″ or greater. I generally reserve this technique for larger trees, those that I will be climbing with a rope and harness. Unless there is a specific disease I am trying to control, 1/4″-1/2″ deadwood and above is all that is necessary to remove from the tree, for the sake of esthetics. Going beyond that point is largely a waste of energy as it cannot be discerned from the ground at heights of 40′ or more.
