Tree Pruning Begins with Safety

Home Grown  by Keith Reed
We will soon be approaching the ideal time of year to do corrective pruning on most ornamental shade trees. Exceptions are those plants that might be a little bit cold sensitive such as fruit trees and a few evergreens which should be pruned in the very early spring after the threat of the deepest cold has passed. Please keep the following tips in mind if you do your own tree care.

First and foremost is safety. Tree pruning or removal can be dangerous in a number of ways. Always make sure you have a thorough understanding of proper chainsaw operation and maintenance. If any piece of equipment screams “read the operator’s manual”, it is the chainsaw. Not only will the manual provide helpful tips for keeping the saw itself in top shape, you will also learn proper technique to prevent injury from kickback, premature felling, or damage caused by swinging limbs.

Ladders can be almost as dangerous as chainsaws (and the combination of the two can cause nightmares). ALWAYS check for nearby power lines and other utilities. Also think about worse case scenarios when it comes to ladder placement. Ask yourself “what happens if I fall off” or “which way do I go if this limb falls and takes the ladder out”? This thought process should even be a part of tree work when you are standing on solid ground as large limbs can impart more damage than the untrained person could possibly imagine. Keep in mind that a cubic foot of wood can easily weigh 70-80 lbs. Also, don’t overlook simple safety items like eye protection, long sleeves, and gloves. Once again, the operator’s manual can be your friend.

Also, if you have overhead wires close by, verify they will not be in the way of a falling limb as you prune. Sometimes looking up at something can skew our perspective, take a close look from several different angles before cutting.

Shade trees should not be pruned just for the sake of pruning. Prune only on an as-needed basis. Examples include dead or diseased wood, suckers or “water spouts”, limbs crossing or rubbing on each other, and structural pruning for small trees.
OSU Fact Sheet HLA-6415 Training Young Shade and Ornamental Trees and EPP-7323 Managing Storm-Damaged Trees provide detailed information on correct procedure.

At one time, it was thought that applying tar or “pruning paint” would help trees to heal properly. Research has shown this to be untrue. As long as a proper pruning cut is made, the tree will normally heal just fine.
