Trees should be periodically pruned and inspected. While tree trimming can improve a tree's health and attractiveness, serious unsafe conditions can quickly develop if trees are not maintained correctly.

• Dying or diseased wood should be removed promptly.
• Thinning of the tree's crown will increase light penetration, and will allow strong gusts of wind to pass through easily.
• Removing lower branches can allow for clearance or to improve views.
• Reducing the size, height or spread of trees can help make them more manageable.
