/Home/Garden Basics/Trees/Tree Diseases/Spruce Tree Diseases/Blue Spruce Rhizosphaera Needlecast Disease

Several conifer species can be infected by Rhizosphaera Needlecast, but this disease is most commonly found on Blue Spruce trees. Healthy Blue Spruce trees will retain their needles for 5 – 7 years. Rhizosphaera Needlecast causes premature needle loss, sometimes to the point where only the current years needles remain on a branch. While Rhizosphaera Needlecast will rarely kill a tree it can disfigure it enough that it loses it appeal in the landscape.
