Tree & Shrub Fertilization
Deep Root Fertilization for Lasting Tree & Shrub Health
Healthy trees start with healthy roots. Skyline Tree Service uses deep root fertilization, the preferred and most effective method for delivering nutrients directly where your trees and shrubs need them most — the root zone.
How It Works
Our certified arborists use specialized equipment to pressure-inject a liquid time-release fertilizer 4–8 inches into the soil in a grid pattern around the base of your trees and shrubs.
Each injection delivers a balanced blend of:
- Mycorrhizae inoculant – enhances root growth and nutrient absorption
- BioChar Vital Blend – improves soil structure and microbial activity
- Micro-nutrients – restores essential elements for healthy foliage and color
- Organic bio-stimulants – strengthen natural defense systems and promote resilience
This targeted application nourishes trees from the ground up — encouraging stronger root systems, vibrant growth, and improved resistance to drought, insects, and disease.
Application Rates
We apply approximately:
- 0.5 gallons of solution per inch of trunk diameter (DBH) for trees
- 0.5 gallons per foot of height for shrubs
This ensures consistent coverage throughout the root zone for optimal results.
Service Cycle
Skyline Tree Service provides year-round fertilization with clients typically placed on either a spring or fall annual treatment cycle.
Our fertilizer remains effective for up to 12 months, and annual re-treatment is recommended to maintain soil health and plant vigor.
Safe, Eco-Friendly & Effective
- Rain will not affect the treatment — rain will actually alow the tree to update the products faster.
- Completely safe for pets and people
- Environmentally responsible: We use BioGreen Organics & American BioChar Compnay products that enhance soil biology
