In March, Tim Back delivered a presentation on The Emerald Ash Borer in the Greater Cincinnati Area multiple times.  You can see this presentation by clicking on the picture of the EAB below.

In June 2009 a research report on Ash tree treatment for the Emerald Ash Borer (EAB) was published by scientific investigators from Ohio State University, Purdue University, Michigan State University and University of Michigan, and University of Illinois.

Their findings identified the most effective treatment for the Emerald Ash Borer (EAB) was emmamectin benzoate.

“A new product that is effective for two years or even longer (emamectin benzoate) has altered the economics of treating ash trees…

Emamectin benzoate is the only product tested to date that controls EAB for more than one year with a single application.

It also provided a higher level of control than other products in side-by-side studies.”

Pneumatic Vertical Mulching and Fertilizing is an integral part of our system for treating and protecting ash trees from the Emerald Ash Borer.

Here is an excerpt from the Arborists’ Certification Study Guide explains what soil compaction is.  And the best solution is Pneumatic Vertical Mulching.

“Compaction is one of the biggest problems in urban soils.  Compaction is often caused by construction, foot or vehicular traffic, engineered soils to support roads or buildings, or other factors.

Compaction reduces total pore space and the proportion of macropores to micropores.  Loams, silt loams, and other soils with a variety of particle sizes may be particularly vulnerable to compaction because small particles are pressed into large core spaces between particles.

Trees and soils are so ecologically independent that it is hard to imaging separating them from one another.  Yet the processes involved with urban development disrupt this ecological balance, creating growing conditions that may range from unfavorable to antagonistic.

It has been said that the vast majority of tree decline situations can be attributed to an initial soil stress.

Trees are living systems driven by energy.  They must obtain sufficient oxygen, water, essential elements and other components from the soil to meet their energy requirements.

Understanding soil is vital to arboriculture because soil is, quite literally, the foundation within which a tree grows.”

From page 32 of the Arborists’ Certification Study Guide, by Sharon Lilly, International Society of Arboriculture (ISA).

Pneumatic Vertical Mulching and Fertilizing, along with regular treatment of ash trees with TREE-age, is why Back Tree Service offers a 100% money back guarantee.  You can read the guarantee by clicking on the image below.
