Beautiful Colorado Blue Spruce Trees
Colorado blue spruce are beautiful trees. Colorado blue spruce trees are Native American trees that originated on stream banks and crags of the western United States. These sturdy trees are attractive in home landscapes where they look great in shrub borders, as backdrops for borders and as specimen trees. Colorado blue spruce grows best in a sunny location with moist, well-drained, fertile soil. It tolerates dry wind and can adapt to dry soil. The tree is hardy in USDA plant hardiness zones 3 through 7. Plant Colorado blue spruce in a hole that is as deep as the root ball and two or three times as wide. When you set the tree in the hole, the top of the root ball should be even with the surrounding soil. You can check this by placing a yardstick or flat tool handle across the hole. After adjusting the depth, firm the bottom of the hole with your foot. It’s best not to amend the soil at planting time, but if it is poor in organic matter, you can mix a little compost with the dirt that you removed from the hole before backfilling.
Compost should make up no more than 15 percent of the fill dirt. Fill the hole half full with the fill dirt and then flood the hole with water. Do not mound soil around the trunk. Caring for Colorado spruce trees can be simple once the tree is established. Water it regularly to keep the soil moist through the first season and only during dry spells thereafter. The tree benefits from a 2-inch layer of organic mulch that extends just beyond the tips of the branches. Pull the mulch back a few inches from the base of the tree to prevent rot.
