Crown reduction is a tree pruning technique used in arboriculture to reduce the overall size and height of a tree's canopy. The primary goal of crown reduction is to make a tree more manageable in size while retaining its natural shape and structure. Other benefits of crown reduction include allowing a tree to not interfere with surrounding buildings, power lines or structures. In addition, reducing the weight and leverage of branches can help prevent branches from breaking or falling during storms or heavy snowfall. Crown reduction or (pruning) should be performed by skilled individuals, such as certified arborists or tree surgeons, using proper techniques and tools. Improper pruning can harm the tree, lead to disease, and cause structural problems. It's essential to consider the species of the tree, its age, and the specific goals of pruning when deciding how and when to prune. Pruning is typically done during the dormant season in late autumn or winter, but some types of pruning can be done year-round, depending on the circumstances and goals.
