Pruning Trees- Natural Target Pruning:
The practice of natural
target pruning makes use of the branch collar to identify the proper location to
remove a branch. But there is a three-cut process that must be used to remove
branches in order to preserve the bark tissue and the branch collar.
cut (marked A in figures below) is an undercut about 1/4 through the branch made upward from the
bottom of the branch about one or two inches farther out than the collar.
The second cut
(marked B in figures below) is a downward cut just outside the undercut that actually removes the entire
branch, eliminating the weight of the branch before making the final natural target
cut (marked C-D in figures below) is the natural target cut. The remaining portion of stub is removed
with a cut made just outside of the branch collar tissue.
first two cuts remove the weight of the branch. This will prevent the bark
from being ripped off the trunk at and below the branch collar. In our “rule
of thumb” example, this would be similar to a hangnail on your finger.

When limbs are removed without making an undercut, the bark may be peeled
down the trunk as the limb falls downward.
