Live crown ratio, the percentage of a tree's height covered in living branches and foliage, is one of the clearest indicators arborists use to evaluate structural health, and it's worth understanding before your next pruning job.
A healthy ratio generally sits above a third of a tree's total height, giving it enough foliage to produce energy and enough support along the trunk. When over-pruning or decline pushes that ratio too low, a tree becomes more prone to failure even if it still looks fine from the ground.
Boutte Tree's ISA certified arborists evaluate live crown ratio on every structural assessment across Atlanta, Sandy Springs, Roswell, and the surrounding metro to determine how much pruning a tree can safely handle.
