Picea Pungens are a virtually maintenance free conifer, they do not require pruning They will tolerate all soil types but do better in acid or neutral soil that is moist and well drained.
Picea Pungens, commonly known as Colorado spruce or Blue Spruce when not in standard form is a medium to large, narrow, pyramidal conifer with horizontal branching to the ground. Its hardiness comes from its origins in the central Rocky Mountains where it is typically found growing in moist locations from 6000 to 11000 feet in elevation. Stiff, bristly, four-angled, green to blue-green to silver-blue needles point outward from the branches in all directions. From a purely horticultural point of view, conifer trees with blue or silver blue foliage are generally more coveted than trees with green foliage
