ArborGrow® Soil Therapy

ArborGrow® Soil Therapy

Healthy trees require rich soil teeming with living organisms. Urban soils are sterile and lack organic matter like that found on the natural forest floor. Nutrients are deficient and pore space for oxygen and soil moisture has typically been eliminated by compaction. No wonder the life expectancy of urban trees is a fraction of those found in nature. Urban trees, critical to our quality of life, are terminally threatened.

Fertilizing trees only makes it worse. Nitrogen fertilizers add salt, destroy essential microbes, create chemical imbalances, and force excess growth. Forcing rapid growth increases stress on already struggling plants. Although a recently fertilized tree may look a little greener, its internal systems and complex relationship with the soil may be at severe risk of failure. Fertilizing trees is similar to taking steroids to speed up muscle growth. The side effects can be devastating. In addition, fertilizers leach into storm water and end up destroying the natural systems in our rivers, lakes, and watersheds.

The natural solution to the needs of urban soils is a process called soil therapy. This involves duplicating natural conditions by adding organic matter, micronutrients, and living microbes to the soil, while simultaneously aerating compacted pore space. Our proprietary ArborGrow® mix contains a custom blend of plant extracts, worm castings, Acadian sea kelp, hummates, amino acids, biostimulants, and living, essential microbes. In addition, natural phosphites and select micronutrients are added for stability and to suppress disease-causing soil fungi. Materials are mixed with non-chlorinated well water, and pressure injected to help fracture compacted soils and improve porosity and moisture retention.

Since 1981, Arborguard has partnered with thousands of property owners to provide natural solutions for the preservation of trees in the urban landscape. We welcome the opportunity to meet with you and your trees to create a plan to serve you as well.
