Landscape use: The city of Charlotte and other southern cities planted Willow Oak extensively during this century and it has proven to be an excellent street tree. Prune to space large branches along the trunk so they are well-attached to the tree. Willow Oak forms a tight, compact head with most of the foliage on the outside of the crown. Open-grown trees would benefit from some pruning to thin the crown to develop more secondary branches along the major limbs and increase the taper on major limbs. This would improve the already good wind-hardiness of Willow Oak. But pruning is difficult as there are many short, spine-like twigs which are a nuisance to tree climbers.
