A trees life is not as easy as it may seem. Like any living organism trees are always allocating their limited resources to meet internal growth and defend against a variety of external factors. When a tree health begins to decline, it indicates the trees current growing conditions are not allowing it to meet all it’s needs, or something has overcome its defenses.
Once this downward spiral begins it is very unlikely a mature tree will recover on his own. Timely intervention, and a sustained maintenance plan, can alleviate current tree stress and reinforce against future adverse conditions. Long-term success requires consideration of all a tree’s needs and its environment.
Ideal candidates for long-term, holistic maintenance are trees such as western red cedar, Douglas fir, western hemlock, big leaf maple, and other large, stately trees.
Approximately 95% of the world’s plant species form mycorrhiza and require the association for maximum performance in the field.
Endomycorrhizae—also referred to as Vesicular Arbuscular Mycorrhizae (VAM)—symbiotically associate with about 90% of the plant kingdom. Their origins date back 350–460 million years and were important in the colonization of land by vascular plants. Endomycorrhizae form an intercellular attachment by penetrating the cell wall of plant roots and forming branched structures called arbuscules within the root cells. These arbuscules provide an extensive surface area for the exchange of nutrients through the cell membrane. Mycelia from endomycorrhizae extend from the plant roots into the surrounding soil, gathering nutrients and water bringing them back to the plant’s roots.
