This tree was planted about 30 years ago and was never structurally pruned. Only small low branches were removed for underclearance. As a result of neglect and poor understanding of the treatments necessary for developing strong structure, the tree broke apart on a 60 mph wind. Structural pruning every few years would have prevented most of this damage.
