A tree inhabits the same soil for its entire life. Environmental stress factors in the urban landscape can deplete the soil over time, leaving it exhausted, compacted, and inefficient for sustaining the root system of a healthy tree. Arborgrow® soil therapy is recommended for treating soil deficiencies.

Symptoms of Soil and Nutrient Deficiencies

Soil deficiencies can be complex and difficult to diagnose. Abnormal leaf color, size, shape, and density may indicate a nutrient deficiency in the soil. The symptoms for insect, disease, or herbicide damage are similar. An imbalance in soil pH and chemistry can affect nutrient availability and mimic deficiency. Soil compaction can reduce pore space, root development, and restrict water and nutrient movement. A professional such as a certified arborist can diagnose soil deficiencies and recommend treatment. Fertilizing is a critical step in rebuilding root systems and replenishing energy reserves. Soil testing is used to fine-tune rates and customize micronutrient levels.

A Complete Soil Therapy Program

Arborguard has carefully formulated a soil therapy program to address soil deficiencies and improve the health of urban trees. A complete soil therapy program will:

• Increase organic matter.
• Improve soil texture, structure, and density to facilitate water, air, and nutrient exchange.
• Increase water availability.
• Enrich nitrogen and other essential nutrients.

Arborgrow® is injected into the soil around the tree’s critical root area using high pressure for maximum dispersion and results.

A key component of our soil therapy is Arborgrow®, a soil treatment that we developed based on more than 26 years of proven results. Arborgrow® contains only high-quality ingredients that deliver essential elements such as nitrogen, phosphorus, potassium, and magnesium to meet basic requirements of trees and shrubs. Our nitrogen is slow-release, non-burning, and non-leaching for increased stability. Arborgrow® also contains seakelp, yucca, and other biostimulants that introduce organic matter, improve soil structure, and release trace elements and plant growth hormones. Microbial spores are also introduced to colonize the root zone with beneficial bacterial.

The Right Arborgrow® Formula Can Make the Difference

A tree's demand for energy, and biological level of activity vary with the season. An understanding of energy cycles in trees helps in determining the timing of fertilizers and other soil applications. An Arborgrow® formula is available for each season of our climate. The Basic mix is designed to provide the essential nutrients to sustain tree health. The Super mix includes mycorrhizal spores and other biostimulants for trees experiencing decline or other stress. Studies have shown that mycorrhizae increase the root surface area, thereby increasing water and nutrient uptake. Custom mixes containing iron or other micronutrients may be used to treat specific problems such as chlorosis, or specific requirements of young and mature trees.

Benefits of Soil Therapy

Trees are healthier when fertilized along with aeration and watering. Healthier trees live longer and are more resistant to insects and disease. Older and stressed trees have improved response to the decline process. Increased root development is seen in young trees. A complete soil therapy program will prevent, as well as treat soil deficiencies.
