Alternatives to Colorado Blue Spruce

Colorado spruce (Picea pungens), often referred to as "blue spruce", is a widely-planted tree in Iowa but suffers from some serious disease and environmental stress issues.  Diseases like Rhisosphaera needle castStigmina needle cast, and Cytospora canker are common and often cause extensive damage including needle drop, branch die-back, and death.  Trees do not grow well in Iowa's heavy, often wet, organic soils, and this Rocky Mountain native does not appreciate Iowa's hot, humid summers.  These less-than-ideal growing conditions for this species put trees under stress making them even more susceptible to disease and insect pest issues.  Finally, the mature size of these trees is too large for most residential settings.  

For all of these reasons, Colorado spruce is not always a good tree selection for Iowa.

There are several other species of conifer that can be used instead of this species in landscapes or windbreaks.  Consider planting these trees instead of Colorado spruce.
