Blue spruce evergreen trees (Picea pungens) grow wild in Western North America in U.S. Department of Agriculture plant hardiness zones 3 through 8. This erect tree produces blue-green evergreen needles that are sharp to the touch. Blue spruces reach 30 to 65 feet tall, spreading 10 to 20 feet wide. With good care this slow-growing tree can grow up to 12 inches per year. Blue spruce trees grow well as showcase trees or as part of a windbreak. Examine the location of the blue spruce tree while it is still young enough to transplant.
Increasing the growth rate of Blue Spruce. Discussion in 'Homeowner Helper Forum' started by cmontana, Apr 25, 2005. I planted four Blue Spruce trees last spring. They were 6 foot tall (including the root ball) and we planted them about eight feet apart in a raised berm that is eight feet across and two feet tall in the center. They seem to be doing well, but I'm wondering what I can do to boost their growth rate.
