The Colorado blue spruce tree, whose scientific name is Picea punguns, is a popular evergreen tree used by many homeowners throughout the United States as a landscaping tree.

As known simply as the blue spruce, the Colorado blue spruce tree makes a great windbreak, screen, or border tree on your property because of its large height and width when full grown.

Smaller Colorado blue spruce trees are the most desirable Christmas tree variety. If you are considering planting a Colorado blue spruce on your lawn, consider first learning some interesting and useful facts about the blue spruce tree.

Care and Maintenance

Maintaining Colorado blue spruces includes monitoring for potential pest problems, such as spider mites or pine needle weevils. Spider mites are tiny sucking bugs that feed on plant tissue fluid. Though they are too small for the human eye to recognize any features, their movement is visible. Spider mites often create silky webs on foliage. Severe infestations may result in yellowed dots, leaf discoloration and defoliation. Pine needle weevils display snouted faces and brown bodies measuring approximately 1/4-inch in length. Larvae eat tree roots, while adults chew foliage. Needles often drop, and the pests’ feeding may cause unsightly cankers, but the infestations do not diminish the tree’s health.


Care for spruce trees by controlling problems that arise. You can control spider mites by releasing natural enemies onto the tree. Natural enemies are insects that kill mites without further damaging the desired tree. Predatory mites can be purchased from garden supply retailers. For more severe infestations, avoid harsh chemical pesticides, which often result in increased mite populations. Opt instead for petroleum-based horticultural oils and plant-based oils such as neem, canola, or cottonseed oils. For weevil infestations, no control options are available other than pruning affected plant parts as maintenance. For control of needlecast disease, maintain moist, mulched soil. Apply a fungicide with the active ingredient chlorothalonil for chemical control.
