Willow Oak is a native deciduous tree that may grow 50 to 80 feet tall but can reach up to 100 feet tall. It has a nice balanced rounded form that has made it a popular tree in the southeast USA. It prefers fun sun to light shade in acidic, moist to occasionally wet, well-drained loams but tolerates a wide range of soils. It is drought tolerant once established. Willow Oak is fast-growing and starts producing acorns at age 15-20 years. This tree is a high-value wildlife tree for birds and mammals.
Use this tree as a shade tree in a large yard or park or a street tree but be sure to give it plenty of room to grow.
Fairly disease and pest resistant. Root rot, borers and trunk canker and orange-striped oakworm are potential problems. Chlorosis due to iron-deficiency occurs on high pH soil.
