Healthy soil is a vibrant ecosystem, rich with living and nonliving matter that interact is a complex of physical, chemical, and biological processes. Healthy trees need healthy soil to thrive, but often times, human development compromises soil composition, negatively impacting these vital complex processes. Poor soil composition can lead to a host of troubles that prevent your trees from reaching their full aesthetic potential, or worse, diminish the overall integrity of the tree. The professional staff of ISA Certified Arborists at Dave Leonard Tree Specialists have the knowledge and tools necessary to mitigate existing soil problems, promote sound root development, and enhance soil composition to give your trees the best opportunity for a long, healthy life.
Root Zone Enhancement
The area known as the “root zone” extends 2 to 3 times beyond the drip line (canopy edge) of a tree. Rebuilding soil structure, augmenting soil with organic matter, and mulching to the edge of the drip line provides the root zone with below ground conditions that encourage strong root growth and set the stage for increased vigor in your trees. Our ability to amend and improve the root zone for any tree in any soil is often the single best way to improve the long-term health of your trees.
Soil Decompaction & Vertical Mulching
Soil compaction is one of the most prevalent issues affecting the well being of urban trees. The most effective way to mitigate the problems caused by soil compaction is to increase soil porosity, providing roots with much needed oxygen and growing space. On sites where the preservation of lawn space is important, Vertical Mulching can be performed in order to decompact soils without enlarging the size of the planting bed. A combination of vertical mulching and radial trenching loosens the soil, adds porosity, and improves soil structure without compromising your lawn.
Root Collar Excavation
Girdling roots are a common and deadly problem among trees planted in our urban environment primarily due to improper planting, mulching and poor soil conditions. Girdling roots are roots that grow to encircle the tree, restricting the vascular system, eventually dramatically weakening or killing your tree. Using the SuperSonic Air Knife we can expose and remove these damaging roots and ensure that your trees are left with an exposed root flare. This process reduces stress on the tree and allows the tree to thrive. The earlier in their growth stage that these roots are addressed, the better the chances for your tree to live to its full potential. Trees such as Red Maples, Sugar Maples, any container grown tree, or any tree planted too deep without a visible root flare are at a high risk of greatly reduced lifespan due to girdling roots.
