White Spruce Tree

White spruce is a tall North American evergreen with a narrow crown and straight, stiff needles that range from green to bluish green. Oregon State University describes mature trees reaching about 80 feet and rates the species for USDA Zone 2; the U.S. Forest Service documents its broad boreal range and preference for well-drained soils.

Its scale suits large properties, windbreaks, and naturalistic plantings better than small residential beds. The species varies with site and climate, so allow room for a substantial tree. ## Growing conditions White spruce grows in sun and tolerates some shade. It occurs across a wide range of northern sites and grows best in well-drained soils; moisture and growth rate vary across its broad range. It withstands cold, wind, and crowding once established. ## Maintenance Water young trees through establishment and during prolonged dry periods. Keep mulch over the root zone and clear of the trunk. Prune only dead, damaged, or crossing branches, and avoid topping the leader so the tree can retain its natural narrow form.
