After one
or two years, your tree may need periodic pruning to ensure both the tree’s
health and a pleasing shape for future growth. Prune to correct the following situations:
- Remove dead and dying branches to prevent insect attack and disease.
- Remove crossed branches or branches that form a fork or tightly angled V. This prevents poor structure and
growth form. Prune away the branch that contributes the least structural
benefit to the tree’s crown.
Reasons To Prune A Tree
Protect
a tree’s trunk from damaged called girdling. It can be caused from lawn
care machinery and items tied around the base of the tree.

3 Simple Steps
Determine the location of the cut. Then use a pruning saw to remove
a branch with three separate cuts:
- Under Cut

Make an under cut about one foot from the final cut location. Cut only about one-third of the way into the branch.
- Top Cut

Make a top cut a few inches
further out from the under cut. Cut through the branch. This removes the
bulk of the branch’s weight to prevent splitting on the final cut.
- Final Cut

Make the final cut to remove the remaining
stub. Do not cut the branch flush with the trunk. Instead, cut at the
branch collar, the point a few inches from the trunk where the branch
becomes narrower.
Caution: Do not prune trees near power lines! Call your
utility provider for service.

Prevent Oak Wilt
To prevent the spread of disease and insect infestation, follow
these guidelines when pruning:
- Disinfect pruning tools between work on each tree with 70% alcohol.
- Remove and dispose of all cuttings that fall to the ground.
- If you are near an Oak Wilt disease area, immediately use pruning paint on all cuts and avoid pruning Oak
trees from Feb. 1 to mid-June.
