Pittsburgh Tree Service

We offer the following services

Root Collar Excavation
Many times trees are planted too deeply, and as a result, have a difficulty establishing or flourishing in the landscape. This issue can cause the tree to exhibit early fall coloration, early leaf drop, flat spots or bark missing from the bottom portion of the tree’s trunk, and problems with insects or diseases.

When symptoms such as this occur, a root collar excavation is advisable. At Horhut Tree Experts, we use AirSpade® technology, along with compressed air to establish the proper planting depth of the tree and address any other issues that may be present.


Critical Root Zone Enhancement
The tree trunk and canopy are only ½ of the whole tree. Sometimes we forget about the roots of a tree, because we are enamored with the above-ground portion of trees. But, the Critical Root Zone of a tree is just as important as the tree’s trunk, scaffold branches, leaves, etc.

Critical Root Zone Enhancement is a process that improves the soil under and near the canopy of the tree. This procedure will reduce soil compaction, which is detrimental to a tree’s rooting health. And, aerate the soil using AirSpade® technology with compressed air having no damage to the tree’s root system. During AirSpading®, organic material and required nutrients will be reincorporated into the soil to enhance the development of the tree’s root system and aid in beneficial bacteria growth.


Storm Damage
During extreme storms, even healthy and structurally sound trees can fail and cause the need for eminent action.

Being a current Horhut Tree Expert client in good standing, you can expect a quick response.

  • Once the weather conditions permit, we will visit the site to assess the situation
  • Then develop a strategy to address the conditions present on site; utility lines down, multiple property owners affected, need for a crane service, etc.

Experience the Horhut Difference

In some cases, property owners and managers consider the term “arborist” to be equal across many service providers. But, as the chart below outlines, there are substantial differences among service providers in areas of tree and shrub consultation, recommendation, protection, maintenance, and preservation.
