The main reasons for pruning ornamental & shade trees include safety, health and aesthetics. In addition, pruning can be used to stimulate fruit production and increase the value of the timber.
Pruning for safety involves removing branches that could fall & cause injury or property damage, trimming branches that interfere with lines of sight on streets or driveways, and removing branches that grow into utility lines. Safety pruning can be largely avoided by carefully choosing species that will not grow beyond the space available to them, and have strength & form characteristics that are suited to the site.
Pruning for health involves removing diseased or insect-infested wood, thinning the crown to increase airflow & reduce some pest problems, and removing crossing & rubbing branches. Pruning can best be used to encourage trees to develop a strong structure & reduce the likelihood of damage during severe weather. Removing broken or damaged limbs encourage wound closure.
Pruning for aesthetics involves enhancing the natural form & character of trees or stimulating flower production. Pruning for form can be especially important on open-grown trees that do very little self-pruning.
