There are a few reasons why people trim trees and one of them is for safety reasons. It is a well known fact that dead branches can sometimes fall off and cause serious damage to property or injure people. If branches of trees are obstructing the vision of drivers, they should be trimmed as soon as possible. Another reason people trim trees is for health reasons. Trees that are infected can be saved by strategically trimming away the branches causing the infection. When the crown of a tree is thinned down, it improves air flow. If branches are rubbing together, they need to be trimmed to prevent them from falling on people unexpectedly.
Tree Trimming Techniques
1. General Tree Trimming Tips
The best time to trim a tree is during its so called dormant season although trimming can be done at any time of the year but it is recommended to do it when it is dormant. The only exception to this is when potential hazards are spotted. The second tip is to be conscientious about the sizes of the branches that will be removed. If the branches are less than 5cm in diameter, taking them out makes sense however if they are 5 and 10cm in diameter, one might not want to remove them. If the branches are more than 10cm in diameter, one should take them out if they have a good reason to especially if it can cause accidents. The third tip is only trim branches that are weak, narrow angled and V-shaped. Only branches that are strong need to be retained. The fourth tip is to not trim a branch too long or too close. The key here is to not leave a large stun or take out the branch collar.
2. Trimming Techniques
Before any trees are trimmed or cut, the branch collar is something which needs to be inspected. The branch collar grows from the stem tissue at the bottom of the base to the branch. The branch ridge needs to be looked at which is on the upper surface and is parallel to the branch angle located near the stem. One has to remember to always cut outside the branch bark ridge and angle the cut down and away from the stems without causing injury to the branch collar. This same technique can be applied when pruning living and dead branches. When stems are very long, a three cut technique needs to be used. One needs to make a notch on the side of the stem that is facing away from the branch being retained, a second cut needs to be inside the crotch of the branch and above the branch ridge and a third cut needs to be done to take out the stub by cutting through the stem that is parallel to the branch bark ridge.
