Clear established objectives should be defined when considering tree trimming and pruning. Removing branches from a tree can promote healthy growth of a tree and possibly alter the shape of a tree. Caution must be considered when removing the leaves which will reduce the tree’s overall photosynthetic capacity and could then reduce the overall growth of the tree. The goal is to create good light, air circulation and strength.
Types of Tree Pruning
- Crown thinning is an essential tree pruning procedure that removes smaller, weaker limbs from the tops of your trees. This also allows air and light to penetrate more throughout the tree.
- Removing dead, dying, or diseased branches is an essential part of having trees on your property.
- Reduction cutting reduces the length of a limb by cutting it back to a lateral branch.
- Crown lifting remove the lower branches which raises the canopy.
- Structural cutting helps to reduce structural defects in the tree such as codominant stems. This is best done at the early stage of the tree’s life.
Generally, the best time to prune or trim trees and shrubs is during the winter months prior towhen the bud’s swell which is from November through March when most trees are dormant. The trees are less susceptible to insects or disease. Flowering trees and plants are best pruned prior to leaf emergence or after the blooming has occurred.
When cutting branches of 2 inches or less in diameter use bypass pruners or loping shears, which cut like a pair of scissors.
Using the three-cut method to remove branches.
Cut from the bottom, moving upward about 1/3 of the way through the branch. Next cut downward from the top of the branch several inches beyond the first cut. This cut technique if done properly, eliminates the chance of peeling or ripping the bark as the branch is removed.
Disadvantages of pruning especially excessive pruning can shorten the life of a tree, cause lion-tailing, excessive branch growth and cause wounds that may not heal properly. If a tree was pruned wrong, it can lead to the growth of microorganisms, insect infestation, mushrooms, fungi, and bacteria which can even result in decay of the limbs or the entire tree itself.
Proper tree trimming promotes healthy growth, while at the same time helps to remove unnecessary branches thus providing a healthier, more aesthetically-pleasing tree and landscape.
