Quercus velutina, commonly known as black oak, is a large deciduous tree native to the eastern United States and southeastern Canada. It thrives in well-drained soils and prefers acidic conditions, though it is adaptable to poor, dry soils, including sandy and clay soils. Black oak is best suited for full sun and is commonly found in upland hills, slopes, and ridges, but can tolerate part shade. Prune in the dormant season to prevent attracting beetles that may spread oak wilt. Black oak is a relatively low-maintenance tree, though it may hold dead branches for extended periods and is not as commonly available in nurseries as other oak species. Quercus velutina drops acorns and a considerable number of leaves, with the heaviest shedding in the fall.
