Culture Notes
This narrow oak prefers an area with full sun to light or open shade. Plant it in a location with moist to well-drained soil, although it will tolerate sandy sites and clay if the drainage is adequate. Once established it is drought tolerant, although in prolonged dry weather it appreciates an occasional watering. Little pruning is needed other than to remove dead, broken or poorly formed limbs.
