Rhizosphaera Needle Cast

needlecast in colorado blue spruce

This is most commonly found on lower branches of Colorado spruce, especially where trees are growing in groups or rows where airflow is restricted. This needle-cast disease is caused by a fungus that thrives in dark and moist conditions. Needles on lower branches turn brown and fall prematurely, resulting in branch death.

If you suspect you have trees affected by needlecast, contact the professional arborists at South Metro Lawn and Landscape today for a free consultation.

What to do?

Treatment options exist for needlecast on unaffected trees, but once a tree is infected it is often too late. Consider alternatives such as the Colorado White Fir in new landscapes instead of Colorado Blue Spruce.

Avoid planting Colorado Blue Spruce, and with all Spruce trees, avoid soaking the needles with water from sprinkler systems.
