Quercus acuta

Japanese Evergreen Oak

1. The Japanese Evergreen Oak is an evergreen tree that can reach a height of 30 to 50 feet (9 to 15 meters) with a spread of 20 to 30 feet (6 to 9 meters). It has a dense, rounded crown and dark green, glossy leaves that are lance-shaped and serrated along the edges. The bark is grayish-brown and develops shallow fissures as the tree matures.

2. 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.

3. 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.

MAINTENANCE NEEDS:  Medium Maintenance.  Oaks are susceptible to a large number of diseases, including oak wilt, blight, root rot, anthracnose, oak leaf blister, cankers, leaf spots, and powdery mildew.  Potential insect pests include scale, oak skeletonizer, leaf miner, galls, oak lace bugs, borers, caterpillars and nut weevils.
