Many species of Picea look very similar to Firs; however, the cones of Picea hang from the branches as opposed to upright on the branch as Firs do.
Spruces are evergreen, coniferous trees with a narrow, conical habit. They are an important source of wood pulp and are very popular as Christmas trees.

Once established Spruces need very little water except for Brewer's Weeping Spruce (P. breweriana), which needs regular water.
In winter, check for green aphids amongst the needles. Pine needle scale can also be a problem. In the Rocky Mountain states, spider mites and tussock moths can infest Spruces. Cooley Spruce gall adelgid is an insect similar to the aphid that feeds on the tips of branches of Spruces and causes a green gall to form. The galls gradually turn color to a light purplish tan.
