Just wanted to let you know about a new tree resource. With the help of Cyndy Ash Kanner, and reviews from Joe O’Brien of the USDA Forest Service and Jim Walla of NDSU, we now have a new publication on diseases of spruce trees including photos, id info, biology and management. The spruce diagnostic tool will be coming soon and will link directly to this pub for management info.

Eli ‘s work addresses Minnesota forest ecology & management. He’s based in St Paul.

  1. We have 6 blue spruce in our 1 acre yard. They form a fence but 15 feet between growing on the high part of land. They are about 25 years old. One is getting brown from the bottom to about waist high on the NE side. Another is getting brown in the trunk area. The rest are fine. Any thoughts?
