The Colorado blue spruce tree grows from between 90 and 135 feet tall and is from 20 to 30 feet wide when mature. Its color varies from silver to blue-green and, since it is an evergreen, it never loses its leaves.

When caring for a Colorado blue spruce, keeping an eye out for insects and treating as necessary is important. All the dead wood should be pruned in the spring and young trees should be watered thoroughly once a week in hot weather. This should be done by placing the hose at the base of the tree and allowing the water to trickle into the soil.

Because of the blue spruce's size, it is best as an only tree used for accent in a yard and does not work well as a screen or privacy plant. As the tree gets old, its branches begin drooping, and it will lose its shape.

Some common insects known to hurt the blue spruce include spider mites, spruce budworms and spruce gall aphids. When a tree becomes infested with these bugs, the tips of the branches will begin to die. Insect damage may also ruin the symmetry of the tree.
