FERTILIZATION, SOIL MANAGEMENT, & ROOT CARE

Healthy soil is essential to healthy trees. Urban and suburban soils are often lacking certain characteristics that are found in the forest where trees naturally thrive. Our soil management services start with a soil sample that is taken from the site and analyzed. These results are used to determine if and which soil amendments will be beneficial. We also visually inspect the tree for signs of compacted soil or symptoms of root problems hidden below the ground. Compacted soil is the leading cause for stress and eventual death of trees in urban and suburban environments.

We use a tool called an Air Knife which uses highly compressed air moving at very high speeds through a patented nozzle. This loosens the soil to improve aeration and reduce soil compaction. By using air, there is no negative impact on the root system that you would have if you tried to mimic this process using a shovel or auger. At this time we can adjust the soil chemistry as needed, based on the results of your soil analysis.

The Air Knife is also handy for exposing and treating various other root problems such as stem-girdling roots, trees that have been planted too deeply, or over mulching.

Trees planted at the proper level will flare out where the roots begin to meet the soil. When mulching around trees, avoid piling mulch against the stem of the tree as this often promotes rot or rodent activity.

Trees planted too deep are much more susceptible to poor root structure, and increased risk of decay at the base

After using the Air Knife to excavate the soil from around the trunk and exposing the root system, it is clear that this tree has girdling roots which inhibit the proper flow of nutrients and water to the tree. If recognized early enough, it is possible to prune the root system to promote healthy root structure. If left to run its course, the tree would most likely show signs of stress in the canopy such as small or discolored leaves before eventually starving to death from lack of nutrients.
