Root and Soil Mediation

Root Collar Excavation, Root Zone Aeration and Decompaction

Your tree's root system plays a vital role in its health. Fine roots absorb water and nutrients, store the tree's energy reserves, provide structural support, and allow for the exchange of gases. A tree's root system is massive but is also delicate.

As Arborists, we often encounter trees that have been planted too deeply, have excessive amounts of mulch piled around their trunks, or the soil is compacted in the critical root zone due to construction, heavy machinery or vehicle traffic.

In all of these cases, the tree's health will be negatively impacted due to the lack of water infiltration, nutrient flow and greatly reduces gas exchange in the root system. These issues combine to greatly stress the tree, and if left unchecked could result in girdling roots, increased susceptibility to insect and disease infestation, and in many cases death.

The solution

Root Collar Excavation and Root Zone Aeration employs the use of an air knife to loosen the soil, eliminating compaction and allow for any root pruning addition of missing organic material and nutrients back into the soil.

Harnessing Compressed Air

The Air Knife or Air Spade, uses compressed air forced through a supersonic nozzle that then loosens and crumbles the compacted soil. This exposes the tree's root structure with minimal to no damage. Because tree roots are not porous, they are not disturbed by air excavation.

At this time, any root pruning of damaged roots will be done. In addition we will incorporate a high amount of nutrient rich, organic compost mixed with BIO-CHAR in to the soil.

Our certified arborists can easily identify any roots that should be removed or trained. We will also incorporate any necessary nutrients or compost back into the soil, then water to replace any lost soil moisture.

The information that we learn from actually looking at the roots can help us as arborists take the steps necessary to safeguard your tree's health.


You and your tree will benefit from increased fine root growth and restored vigor and canopy growth.

We help you avoid much more costly issues in the future and more importantly preserve ancient trees and 'soon-to-be ancient trees!
