  • Ash Anthracnose

    Anthracnose is a catch all phrase to describe leaf and shoot disease on many types of trees and shrubs.  In green ash trees anthracnose appears, usually in the spring, as sudden leaf loss.  A wet spring, along with the presence of the fungus, contributes to anthracnose severity.  Fallen leaves are usually smaller, they may have […]

  • Iconic Sequoia is No More

    It sad to hear of an ancient tree falling over.  More amazing is that after being damaged by fire and human cleverness it stood for another hundred years or more.  Trees can’t run from threats so they adapt a little and adapt a little more to abuse — This ability is why trees are the longest […]

  • Bird populations might benefit from the Emerald Ash Borer in our Trees

    I recently read the 2013 study, titled Effects of emerald ash borer EAB on four species of birds by Koenig, Liebhold, Bonter, Hochacka, and Dickinson from Cornell Lab of Ornithology with great interest.  In Michigan they found both red bellied woodpecker and white breasted nuthatch populations increased in areas of and EAB infestation from 2005 – […]

  • Woodpeckers and Emerald Ash Borer

                    At the Northern Green conference in January of 2017 Mark Abrahamson, Assistant Director of the  Minnesota Department of Agriculture, presented copious evidence of the direct correlation between woodpecker damage to ash trees and an Emerald Ash Borer (EAB) infestation. Woodpecker damage is described in two ways: Flecking, […]

  • Have you met the Emerald Ash Borer?

    In January of 2017 I attended the Northern Green, an annual green industry get together, and it’s Master Classes for tree geeks. The dangers of standing ash trees falling apart due to heavy infestations of emerald ash borer (EAB), was one of the main themes of the conference. The effect of EAB, an agrilus beetle […]

  • Have Your Flossed Your Trees Lately?

    Stem girdling roots grow against soil covered tree trunks, compressing the vascular system, and ultimately reducing the tree’s life span. As the trunk expands, the roots close in on the trunk, forming a tourniquet which slowly strangles the tree to death. When these trees fail, they break off at the base like a ball and […]

  • Trees and Pesticide use: Finding a Balance

    I try to see both sides of most issues. I’m willing to consider two seemingly contradictory, yet only contrary, viewpoints at the same time. I’m a Vikings fan, but I don’t hate the Packers. (I do hate the Cowboys since in my youth Drew Pearson did push off.) I think the conservatives have great ideas; […]
