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 and to
improve tree structure, enhance vigor, or maintain safety. Because each cut has the potential
to change the growth of (or cause damage to) a tree, no branch should be removed without a
reason.
Removing foliage from a tree has two distinct effects on its growth. Removing leaves reduces
photosynthesis and may reduce overall growth. That is why pruning should always be
performed sparingly. Overpruning 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, so they tend to grow longer than they would
without pruning. 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, or the removal of large limbs, then
using personal safety equipment, such as protective eyewear 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
which type of pruning is necessary to maintain or improve the health, appearance, and safety
of your trees.
