It is a truly cold adapted tree and is very resistant to winter injury. It prefers rich moist soil in full sun, and also thrives in dry, well-drained sites. This evergreen conifer tree has a medium growth rate and requires little, if any, pruning. Deer dislike Black Hills Spruce. This tree is commonly used for windbreaks, privacy screens and accent plantings. It will reach a height of six feet in nine years on a good site.
