Growing Conditions: This oak tree thrives in full sun to partial shade and prefers well-drained soil. It is adaptable to a range of soil types, including sandy, loamy, and clay soils. It is also tolerant of urban conditions and pollution, making it suitable for planting in urban areas.

Maintenance: The Japanese Evergreen Oak is relatively low-maintenance once established. Regular watering during dry periods is important, especially during the first few years after planting. Mulching around the base of the tree helps retain moisture and suppress weeds. Pruning is generally not necessary, but you can remove any dead or damaged branches as needed.
