Why should I prune?
Safety, tree health, aesthetics, and value are the primary reasons for pruning trees. A single pruning can accomplish more than one objective and save time.
Safety
Pruning for safety removes branches that could fall and cause personal injury or property damage. Removing low branches in fire-prone areas can prevent a ground fire from climbing into the tops (crowns) of the trees.
Tree health
Pruning for tree health removes diseased or insect-infested wood, thins the crown to increase airflow and reduce some pest problems, and removes crossing and rubbing branches. Removing broken or damaged limbs encourages wound closure and prevents diseases from entering the tree. Pruning encourages trees to develop a strong structure and reduces the likelihood of damage during severe weather.
Aesthetics
Removing lower limbs to improve visibility in your woods and to stimulate flower production are primary reasons to prune for aesthetics. Pruning also increases the amount of sunlight that reaches the ground, stimulating growth of wildflowers and flowering shrubs.
Value
Pruning for value increases the amount of high value wood products produced on individual trees. Pruning preferred trees produces knot-free wood. (See the Backyard Woods Tip Sheet on Help Your Preferred Trees Grow for more information) A knot is the portion of a branch that becomes incorporated within the trunk of the tree. Knots are the primary reason for reduction in lumber value.
