Common Diseases of Blue Spruce
Blue spruces are a favorite conifer of Iowans and several reasons. In addition to being a beautiful tree that maintains color year round, these trees make an excellent wind break and for the most part grow quite well here. When we see diseases in blue spruce, which is not often, it usually is one of two different types--Cytospora Canker and Rhizospharea Needle Cast.
