Willow Oak is a deciduous tree in the beech family that is native to eastern and central USA. It may grow 50 to 80 feet tall but can reach up to 100 feet tall and is long-lived. In NC it can be found in all areas of the state. It has a nice balanced rounded form that has made it a popular tree in the southeast USA. Willow Oak is fast-growing for an oak and starts producing acorns at age 15-20 years. This tree is a high-value wildlife tree for birds and mammals.
Willow Oak is easy to grow in acidic, average, medium to wet, well-drained soils in full sun to light shade. It is adaptable to a variety of soil types. It is utilized as a shade tree in commercial establishments, parks, golf courses, large yards and as a street tree.
Fairly disease and pest resistant. Root rot, borers, trunk canker and orange-striped oakworm are potential problems. Chlorosis due to iron-deficiency occurs on high pH soil.
