Spruce trees are planted throughout North Dakota, often as ornamental shade trees and shelterbelts. These conifers are beautiful, but they also suffer from many environmental and pest problems. Any given tree can be affected by several problems at the same time.
This guide published by the NDSU Extension Service will help the reader diagnose and understand what can – and can’t – be done to maintain or improve the health of spruce trees in North Dakota. The guide begins with a section on spruce identification, followed by a listing of disorders and pests. When using pesticides, be sure to read, understand and follow all label directions.
