How to Plant a Colorado Blue Spruce Tree


A stunning variety of evergreen with silvery-blue needles, the Colorado blue spruce (Picea pungens var. glauca) can grow to over 100 feet and spread 30 feet wide. It grows in a pyramidal shape with inch-long needles and light brown cylindrical cones. It prefers moist soil and full sun, and is hardy in zones 3 to 7.

Planting Your Spruce Tree

Step 1

With a shovel, dig a hole at least three times the diameter of the tree's root ball, and as deep as the container or root ball.

Step 2

Loosen the soil around and in the hole and add peat moss to the soil, in a mixture of 1 part peat moss to 2 parts soil. This will aerate the soil and keep in moisture.

Step 3

If you have a tree wrapped in burlap, set it in the hole. Cover about two-thirds of the burlap with soil, tamping it down as you fill the hole. Remove the string from around the burlap, open it up and spread it out. It will rot on its own. Continue to fill with soil, up to the dirt mark on the trunk of the three.

Step 4

Water generously and let the water soak in. Create a moat around the hole with a 2-inch rim and add more water. Let it soak in.

Step 5

For trees in containers, take the same same steps except that you remove the container by cutting it away. With your fingers or fork, spread out the roots gently to separate them in case they've become too compacted.
