Description:
This wet site loving species has one of the largest range of willows in North America. Preferring moist, well-drained, wet soil, black willow is intolerant of drought conditions. This tree is susceptible to ice damage because of its weak-wood and weak branch structures. Regular pruning is required in a managed system. Roots are also known to invade sewer pipes. It is important to keep these factors in mind when selecting a planting site.
