It grows in an open sunny to semi-shaded, protected to expose positions and tolerates most well-drained fertile moist soils with a pH 4.5 - 5.5. It is drought tender but frost tolerant.

Willow Oak is grown for its willow-like appearance and autumn foliage colour preferring a moist position. It is planted as a specimen around a water feature or used for summer shade in parks and large gardens. It establishes in 3 to 5 years and in warmer climates it may be evergreen. It can also  be grown as a street tree and around buildings. ID 1607
