When removing a live branch, prunin~ cuts-should be made in branch
tissue' just outside the branch bark ridge and collar,'which are trunk
tissue. (Figure 1). If no collar is visible, the angle of the cut
should approximate the angle formed by t~e brandh bark ridge and
the trunk. (Figure..'Z)
When removing a dead branch~ the final' cut should b; made outside . '.
the col.lar of. live callus tissue. If the collar has grown out along
the branch .stub, only the dead stub should be removed, the live'~ollar
.should remain intact, and uninjured. (Figure 3)
