Tree trimming, also known as tree pruning, is the selective removal of tree limbs. There are many reasons to prune or trim tree limbs. • Dead or damaged limbs • Weak or diseased limbs • Crossing or rubbing branches can cause wounds for disease or insect damage • Low hanging limbs interfering with riding mower, clearance for parking or walking • Tree limbs dropping debris on driveway, sidewalk or near areas for entertaining as in the patio or swimming pool • Dangerous limbs too close to structures • “Raise” the canopy or “limbing up” to allow light through the tree for grass growth; provide greater road visibility • Tree growth interfering with satellite reception • To enhance a scenic view
