Armillaria Root Disease
From: Steve Williams Landscape, Berkley, CA
We treated six 30-50 year old Japanese maples that had construction damage and were suffering from Armillaria root disease. The fungus was under the bark, the bark was peeling off, and gooey resins & exudates were seeping out from the trunk - both clear signs of extreme stress. Water movement up and down the tree was completely impaired. The tops of the trees defoliated, causing more stress and making the remaining leaves turn red prematurely.
Starting in 2009, we began treating the trees with Companion Biofungicide and Essential Plus, a bio-stimulant. We lost one tree - the one that had been most badly damaged - but the other five trees experienced a remarkable turn-around. By Spring 2010 all five remaining Japanese maples leafed-out nicely, returned to more normal coloring, and looked much stronger than before. Thanks for your help with this project!
