There are two main types of cuts: heading and thinning. Heading cuts are made at the ends of branches - that is, they make branches shorter.
Thinning cuts are cuts that remove whole branches, or small branches along the stem of a larger branch. The tree responds to these as cuts as follows:
A branch that is subjected to a heading cut becomes sturdier and more vigorous. A heading cut induces sprouting and increases the rate of diameter growth. It may also induce the formation of fruiting buds, Thus, heading cuts result in a flush of growth and vigor. (This is something that the companies who “top” or “head back” the trees and branches along our powerlines haven’t noticed yet - the more they make heading cuts, the more the tree grows.)
Thinning cuts result in decreased vigor and, to a degree, weaken the branch. This is appropriate where upright growth is too repid, or where the upper branches in a tree
