The Colorado Blue Spruce thrives in full to part sun and adapts to any soil that is well drained. A neutral to acidic soil is best. If you know you have an alkaline soil choose an acidic fertilizer like Espoma's Hollytone. After planting, adding a layer of 2 to 3 inches of mulch will help keep the soil moist. Do not allow the mulch to touch the trunk as this increases the chances of pests and disease. Water your new tree deeply a couple times a week for the first month or two. After your plants are established, they only need watered when the soil is dry. This Spruce is drought tolerant after establishing. Fertilize when planting and in early spring yearly with a slow release fertilizer. If your soil is on the basic side choose a fertilizer for acid loving plants. The Blue Spruce is wind, cold, and deer resistant.
When properly cared for, the Blue Spruce rarely has issues with pests and disease. If you notice brown dry spots on your Spruce Spider Mites may be the culprit. Treat with insecticidal soap for minor infections and Bifenthrin or Carbaryl for more severe infestations. Do not use horticultural oil on Spruces.
