About Pin oak
Quercus palustris, commonly known as pin oak, is a medium to large deciduous tree, valued for its beautiful pyramidal shape and deeply lobed foliage that turns vibrant red in autumn. It is ideal as a shade tree or a specimen plant in large parks and gardens, where its elegance can be fully appreciated.
Native range
Eastern North America
Care tips
It requires full sun for optimal growth and intense autumn coloration. It prefers acidic, moist, and well-drained soils; lack of acidity can lead to chlorosis. Ensure regular watering during dry periods, especially in its early years. A common mistake is planting it in alkaline soils, which can cause nutritional deficiencies and poor growth.
