We are consistently seeing a considerable increase in pests & diseases, compromising tree health which contributes to the overall decline of the tree. Decline is rarely caused by a single factor. In most cases, several agents act together over more than one growing season and collectively result in decline.
The root system is the site of action for many of these factors. Anything that causes root death will eventually result in twig and branch death, as the impaired root system is unable to adequately supply water and nutrients to the entire tree canopy.
Some conditions, such as drought or defoliation by insects, contribute to decline. They weaken the tree and allow other agents, such as pathogenic fungi or boring insects, to cause more damage than would otherwise occur in a healthy tree. Some infectious diseases, those that may spread from other plants or organisms, can be the primary cause of decline symptoms. Adverse environmental conditions may accelerate the progress of the disease. Common activities that contribute to root injury are construction, soil compaction by foot or vehicular traffic, and de-icing salt.
To address this, we apply a tree stimulant that can boost growth and vigor by increasing plant development, activating the root system, and improving nutrient absorption. The stimulant, BIORUSH PLUS, is injected into the soil around the tree. This saturates the soil and allows the root system to absorb the compound, increasing the amount of usual nutrient uptake.
A healthy tree is more resistant to ward off pests and diseases. If you are concerned about or unsure of the health of your trees, please call Denise at (802) 464-3603.
