Granted that in some cases pruning will have to be severe, but if it is done properly the tree will have a chance to live. When a large branch is cut off and a stub is left, the growth processes stop in the projected stub, but continue their natural course of flow at its base in the parent branch. Each year as the tree grows it builds up a new growth ring around the stub. This is noted as a swelling, and will continue to grow in size each succeeding year. In the meantime, the dead stub is exposed to the elements and begins to rot away. In time it will decay back to the stem or trunk and be sloughed off and the original wound may close over with new growth rings. Usually before this happens, the organisms causing decay of the stub enter the main stem and begin their slow but deadly work there, so that in time the entire tree may become decadent.
