This tree would have otherwise died without the intervention of a pneumatic tool to break up, or decompact, the soil, along with vertical mulching and fertilizing.

“The results are convincing us that this is the way forward with many trees that appeared to be in a mortality spiral and well beyond making enormous progress and showing signs of improved growth and vigor.  A 150 year old deodar cedar cedrus deodara behind the Rose Garden infected with honey fungus and holding less than 10% of foliage was one of the first trees decompacted in 1998.  Today this tree still survives with a crown density of approximately 60% and increasing every year.  There is no doubt that this tree would almost certainly have died within two or three years had we not intervened.”

Note that the pneumatic method that they use in the U.K. at Kew, is very similar to what we use at Back Tree Service.  The difference is that the filler and fertilizer are matched to local soil conditions.

Located in the United Kingdom near London, Kew Gardens is one of the most prestigious gardens in the world.  It’s official name is The Royal Botanic Gardens, Kew and it was created in 1759.  The Director of the Royal Botanic Gardens, Kew is responsible for the world’s largest collection of living plants. The organisation employs more than 650 scientists and other staff. The living collections include more than 30,000 different kinds of plants, while the herbarium, which is one of the largest in the world, has over seven million preserved plant specimens. The library contains more than 750,000 volumes, and the illustrations collection contains more than 175,000 prints and drawings of plants.  Source Wikipedia.

The decompaction programme on trees at Kew

What follows is a guideline for watering trees.

Schedule:

May, or temperatures 70 to 79 ºF, water every 6th day

June, or temperatures 80 to 85 ºF, water every 5th day

July and August, or temperatures 86 to 96 ºF, water every 4th day

September, or temperatures 80 to 85 ºF,  water every 5th day

Trees should receive approximately two to three inches of water each time.  This can be measured by simply placing a pan by the tree and then measuring the amount of water that is accumlated in it.

Note:  Do not water every day.  Less frequent long soakings (saturation), followed by skipped periods allow for oxygen availability.

To know you have watered deep enough for a tree, you must be able to probe in the soil at least 6-8” using a shovel.  But I recommend a Ross root feeder.

The 2007 drought was the worst in over 30 years, only to be followed by another drought in 2008. Then, that same year, hurricane Ike hit our trees like a thousand pound sledge hammer.  And following that,  the 2010 drought severely damaged our surviving trees.

Trees need more water than grass. A good lawn does not mean the tree’s root system is getting enough water to preserve the tree’s health, ensuring survival. Conventional watering methods to save trees result in water bills that are unbelievably high.

Solution: Make Your Trees Healthy and Happy.

To make trees healthy enough to fight against the drought requires aggressive action. Our heavy clay soil is like concrete, and demands soil remediation.

1. We pneumatically install 2 inch holes, ten to twelve inches deep, every three to four feet on center, all under the canopy of the tree. These safely aerate the roots.

2. We then backfill the holes with a special aggregate mixed with a slow release fertilizer, offering nutrients to the tree for the following 18 months.

3. These miniature water wells ensure that when you water, it goes to the roots immediately.

Benefits

1. Direct water straight to the roots to preserve tree health and save your trees.

2. Reduces the amount of needed, and saves money.

3. Time release fertilizer stimulates new root growth and promotes tree health.

Your ash trees are not doomed to die

June 9, 2010

It is commonly known that the Emerald Ash Borer (EAB) kills ash trees. There is a misconception that there’s no completely effective treatment and eventually the tree must be taken down. This is completely false!

In a recent article, “Emerald Ash Borer Population Growing,” Paul Drury, assistant administrator of Anderson Township, did a great job of describing the problem. However, he concluded his article with a defeatist attitude that revealed a lack of knowledge. Just like Mariemont, and many other municipalities, individuals are not up with current research or are mislead.

The customer desires to maintain a strong, healthy, and stable oak tree.  We used Cambistat from Rainbow Treecare  Scientific Advancements to focus the tree’s energy on stronger root and leaf development through even distribution  in the tree.

As can be seen in the pictures, I was assisted by Stephan Carbonara of Rainbow Treecare  Scientific Advancements.  Stephan is a technical field representative.

55.25 inches in diameter!

This, is a BIG tree

After measuring, the next step is to dig a trench around the tree.

Next, the Cambistat formulation is mixed.

Here we see Stephen on the left, and Darrell on the right.

The Cambistat formulation is now applied into the trench that we dug.  The process is called soil drenching.

Applying Cambistat formulation

The process did not take long, and is a procedure used in plant health car to strengthen the tree, increase health and focus the tree’s development in the roots and leaves.

Jeff McKinney, a business reporter with the Cincinnati Enquirer, wrote a great article on Tim  changing the Back Tree Service business model in order to focus on treating ash trees in the Greater Cincinnati tree service area in order to protect them from the ravages of Emerald Ash Borer.

You can read the entire article by clicking on the image below.

This article covers the auction and the reasons behind it.  One key point from the article is that doing nothing about treating the Emerald Ash Borer in Cincinnati will result in  a loss of up to 25% of the trees in Cincinnati within 2-5 years.  Don’t let anyone, arborist or other, talk you out of taking action.

This is the result of four years of planning to move the company from a tree removal, or tree mortician business, to a tree physician business.  Tim has always been about saving trees.  And now is the right time to change our business model.

The new business model will be like the building industry general contactors.  We will retain critical skills for saving trees from infestations in house.  The tree removal and pruning business will be subcontracted.  The pricing will be the same to the customer and we will use the best skilled people in the Greater Cincinnati Tree service area as subcontractors.

Tim knows who the best are. After all, he must have trained half of them over the 23 years Back Tree Service has been in business.

Here is an excerpt from the Arborists’ Certification Study Guide explains what soil compaction is.  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).

While there, he met the Arborjet team of Peter Wilde, CEO, Russ Davis, COO, Rob Gorden, Sales Executive and Joe Aiken.

Their presentation was  very impressive, but Tim being Tim, said “Show me your treated ash trees in the middle of a mess.”  And so they set up the trip to Romeo, Michigan so Tim could see first hand the results of their treatment system.

The results can be seen in the post Tim’s trip to Romeo, MI July 2007 in the Emerald Ash Borer blog.
