Culture and Maintenance |
Grows well in a wide range of soil types. No special maintenance required in the Inland Pacific Northwest. Colorado spruce trees may get Cooley spruce gall aphid, but they are not as susceptible to it as other spruces are. This insect causes the branch tips to swell and die, and these galls may be mistaken for small cones. Another insect, the spruce aphid, may be a problem in warmer areas. |

USDA Zone 2. |
Other |
Provides excellent shelter for small birds. |
Cultivars |
Named cultivars are typically selected for bluer color or special forms; these will be sold as grafted plants. Unnamed trees are typically started from seeds, so these will be variable in color and form. |
