Blue Spruce Transplant (2'+)
Colorado blue spruce typically reaches a height of 50 to 70 feet and spread out 10 to 20 feet. Its silvery-blue needles are prickly to the touch and aromatic. Its pyramidal shape makes it a classic choice for a Christmas tree. Colorado blue spruce trees don't need to be pruned, but they can be pruned if you wish to promote denser foliage. Prune off half of the fresh growth on each candle (i.e., growing tip) in spring. They prefer full sun with at least 6 hours of direct sunlight.
