Growing directions
Plant in moist to wet, acidic soil in full sun; pin oak is the most widely planted native oak in urban landscapes because of its symmetrical pyramidal form, fast growth (1–2 ft/year when young), ease of transplanting, and tolerance of clay and periodic flooding. The deeply lobed leaves turn brilliant red in fall, and the tree retains many of its dead lower branches in a distinctive downswept arrangement — a characteristic silhouette. Pin oak strictly requires acidic soil (pH 5.0–6.5); in high-pH soils the tree develops iron chlorosis with yellowing leaves and declining vigor. Avoid high-pH soils or amend with elemental sulfur before planting. The small acorns are among the most important wildlife foods in eastern North America, consumed by over 100 bird and mammal species.
