Quercus palustris, commonly known as the pin oak, is a native to the northeastern U.S. and southeastern Canada. Pin oak is well-suited for moist, acidic soils and is often found in lowlands, floodplains, and stream margins. It thrives in full sun and can tolerate wet and poorly drained soils, though it may be prone to chlorosis in alkaline conditions. Pin oak is a popular shade tree for lawns, streets, and parks. Notable cultivars include Crownright, which has an upright habit and avoids the need for pruning lower branches. Prune in the dormant season to prevent attracting beetles that may spread oak wilt. Quercus palustris drops a significant number of leaves and small acorns, with the heaviest shedding in the fall.
No serious or common issues in the urban environment. Wide range of pests in general for oak (Quercus) species that mainly affect its appearance slightly in minor cases. Two lined chestnut borer has been observed to attack and kill stressed Oak trees in Ontario.
