Soil Amendment & Fertilization Programs
Our Methods
Deep Root Fertilization- We use pressurized soil injection to deliver nutrients and amendments directly into the active root zone.
Air Excavation- Soil is removed, blended with targeted amendments and nutrients, and returned to the root zone during backfill.
Our Core Products
-
BioChar- Activated charcoal blended with humic & fulvic acids.
-
Mycorrhizae- Beneficial fungi that attach to tree roots.
-
BioMP (5-3-2)- Our choice of organic fertilizer that acts as the base of our programs.
Why Our Programs Work
Tree health starts in the soil. These programs improve root-zone conditions by reducing compaction, increasing oxygen and water availability, and supporting beneficial soil biology.
Application Timing
Treatments are applied when trees can actively absorb and use nutrients, not on a fixed calendar. Spring applications support root growth and canopy development, while fall applications focus on root expansion, nutrient storage, and stress resistance.

Service Completion
Our arborists complete the scheduled service using the selected program. Some programs require a single site visit, while others include multiple applications throughout the year — this will be clearly discussed during scheduling.

Follow-Up & Recommendations
Once service is complete, you’ll receive a follow-up summary outlining what was performed and any recommendations for continued care, monitoring, or future treatments.
