All Tree Declines are the same, they are caused by Soil Acidification Sudden Oak Death, Hemlock Decline, Beech Decline, Ash Decline

All tree disease complexes are the same. They have their root in Soil Acidification.  As soils become more acidic toxic Aluminum is released which kills fine feeder roots and Mychorrizal associations in the soil.  The quick way to reverse this is to do a basal bark spray with Potassium Phosphite (Reliant) mixed with Pentrabark frequently.  This novel product restores the mychorrizal associations in the soil which are essential to survival of trees.  The second long term strategy is to apply a calcium rich amendment like Dolomitic Limestone around the drip line and under the canopy of trees to increase the ph of the soil.
