Black Hills Spruce Tree

Black Hills spruce is a dense, slow-growing form of white spruce native to the Black Hills of South Dakota. Oregon State University treats it as Picea glauca 'Densata' and notes the older synonym Picea glauca var. densata; it is generally 20 to 25 feet tall, with older trees sometimes reaching 40 to 60 feet.

Its substantial eventual size makes it useful for a large yard, windbreak, or screen, and its slower growth keeps the outline denser than typical white spruce. The range varies with growing conditions and age. ## Growing conditions Plant in full sun or light shade in moist, well-drained, preferably acidic soil. The species is rated hardy to USDA Zone 2 and tolerates wind, heat, cold, and crowding. The Morton Arboretum reports moderate drought sensitivity, so do not let newly planted trees dry out. ## Maintenance Water during establishment and during prolonged dry spells, then mulch the root area while keeping mulch away from the trunk. Allow room for the broad crown and remove dead or damaged branches as needed. Light shaping is preferable to cutting back the central leader.
