TL;DR
Crown reduction is the pruning of a tree's height or spread by cutting leaders and branch ends back to living lateral branches large enough, at least one third the diameter of the removed stem, to take over growth. Performed to ANSI A300 standards, it shapes a tree away from structures or wires while preserving its form and health.
What it means
Crown reduction is the pruning of a tree's height or spread by cutting leaders and branch ends back to living lateral branches large enough, at least one third the diameter of the removed stem, to take over growth. Performed to ANSI A300 standards, it shapes a tree away from structures or wires while preserving its form and health. It is the legitimate alternative to topping, which makes indiscriminate stub cuts that trigger decay and weakly attached regrowth; a bid that says reduce should never produce a hat-racked silhouette.
