Pruning is the most common tree maintenance procedure next to watering. Pruning is often desirable or necessary to remove dead, diseased, or insect infested branches, improve tree structure, enhance vigor or maintain safety. Since each cut has the potential to change the growth of (or cause damage to) a tree, no branch should be removed without a reason. It is very important to sterilize all pruning tools after each tree is pruned. Dirty tools can spread disease. If a company doesn’t mention this, it is unlikely that they do it.
Removing foliage from a tree has two distinct effects on its growth. Removing leaves reduces photosynthesis and may reduce overall growth. This is why pruning should always be performed sparingly. Over pruning is extremely harmful because without enough leaves, a tree cannot gather and process enough sunlight to survive. However, after pruning the growth that does occur takes place on fewer shoots. Understanding how the tree responds to pruning should assist you when selecting branches for removal.
Pruning mature trees may require special equipment, training and experience. If the pruning work requires climbing, the use of a chain or hand saw, the removal of large limbs, the use of personal safety equipment, such as protective eye wear and hearing protection, is a must. Arborists can provide a variety of services to assist in performing the job safely and reducing risk of personal injury and damage to your property. They also are able to determine what type of pruning is necessary to maintain or improve the health, appearance and safety of your trees.
