Years 5-15Tree 10-40 feet tall with full canopy development; rapid trunk diameter increase

Harvest Tips
Northern Red Oak acorns mature in fall (September-October) and drop naturally. Acorns have a cap covering about 1/4 of the nut. Collect acorns shortly after dropping for best viability; store in cool, moist conditions. Acorns require stratification (cold, moist period) before spring planting. Some wildlife species rely on acorns as a critical food source—consider leaving many for wildlife benefit.
