Tree Pruning
Tree Pruning
Proper pruning is important in
maintaining the health of your
tree. Trees have amazing natural
defenses that enable them to heal---
if they are pruned correctly. Cut-
ting the tree improperly creates
large wounds that leave the tree
open to disease and decay. This is a
quick introduction to proper prun-
ing. It will show you how to make
the right cut and gives some basic
guidelines for making the decision
to prune.
Branch Anatomy
Tree branches grow outward from
the main trunk of the tree (as op-
posed to a fork in the stem). When
a tree branches, it forms a branch
collar and a branch bark
ridge. These two features are very
important when it comes time to
prune.
The branch collar is a distinctive
bulge at the base of the branch,
where it connects to the trunk. It is
actually interlocking layers of cells
of the branch and the trunk, and is
the part that will heal the wound left
by pruning. The branch collar seals
off the wound, minimizing disease
and decay. Proper pruning leaves
the branch collar intact. Branch
collars vary widely from tree to
tree, and from species to spe-
cies. Some are large and very no-
ticeable, while some are much hard-
er to distinguish.
The branch bark ridge is slightly
raised bark between the branch and
the trunk that extends in a line to
each side of the trunk. When the
branch collar is difficult to identify,
the branch bark ridge can help us
decide where to make our pruning
cut. When you are pruning, never
cut behind the branch bark ridge.
Before you begin pruning, look
around at several trees to learn to
identify these two important parts
of the branch.
How to Make the Proper Cut
The branch collar should always be
left intact. Your pruning cut should
begin at the top of the branch collar
and end at the bottom. If the branch
is large enough to require a pruning
saw, it is important to first shorten
the branch to about a 6-8" stub, be-
fore making the pruning cut to pre-
vent the weight of the branch from
tearing through the branch collar.

Tree Pruning (cont.)
Make your first cut about 6 inches out from the trunk on the underside of the branch, about a third of the way
through. Next, cut through the branch just outside your first cut, leaving about a six inch stub on the
tree. Now, you can safely make your pruning cut, leaving the branch collar on the trunk.
If the branch collar on your tree is flat and close to the trunk, so that it is hard to distinguish, use this method
for determining where to make your pruning cut.
Draw an imaginary line from the top of the branch collar to the place where the branch attaches to the
trunk. Then, observe the angle that the branch bark ridge makes with the imaginary line. Mirror the angle
across the imaginary line, and make your pruning cut at this angle. This will keep the branch collar intact.
Pruning: When and Where and Why
The best time to prune your tree is in late winter but before the buds begin to swell. Pruning can also be done
in
the summer well after the tree has leafed out. Avoid pruning just after the tree has leafed out because it has
just used up a lot of energy and won't be able to tackle the job of healing as well. Dying or dead branches in
the tree can and should be removed at any time.
Pitfalls to Avoid:
Do not prune your tree by cutting off a branch flush with the trunk. Although once commonly advised, this
type of cut removes the branch collar leaving a larger, oval wound. Remember, the branch collar is the tree’s
number one defense and so should always be left intact.
After pruning, it is not necessary to use a wound dressing. Wound dressings have not been shown to improve
the recovery of the tree, and in some cases do actual damage to the tree.

Prepare before you pull (that difficult birth) Glenn Selk, Oklahoma State University Emeritus Extension Animal Scientist
Before applying the obstetrical chains to "pull" a calf during a difficult birth, a proper analysis of the situa-
tion must be made. Wash the vulva, anus and the area in between using soap and warm water. Pulling on a
calf should only be done when the presentation and posture of the calf are normal. Normal is defined as the
"anterior presentation" with fore feet first, head resting on the limbs, and the eyes level with the knees. A
backwards calf can be delivered only when both back limbs are presented. Before chains are applied, be
certain that the cervix is completely dilated.
To properly use obstetrical chains when assisting with a difficult birth, follow the this procedure. To attach
the chain, loop it around the thin part of the leg above the fetlock. Then, make a half hitch and tighten it
below the joint and above the foot. Make certain that the chain is positioned in such a manner that is goes
over the top of the toes. In this way the pressure is applied so as to pull the sharp points of the calves
hooves away from the soft tissue of the vaginal wall. (The toes of the backwards calf will be upside-down
compared to the forward presentation).
Obtain a copy of "Calving Time Management of Beef Cows and Heifers" E-1006, an OSU Extension Circu-
lar that thoroughly discusses working with cows and heifers before and during calving season. It can be
