Fertilization
Our blends of nutrients and soil amendments are not simply designed to promote canopy growth but to strengthen and improve the overall health of the tree from the roots up, delivering healthier, greener, more aesthetically-pleasing trees and shrubs. Our uniquely developed mixtures promote stability and growth for trees efficiently and safely, without the worry of harmful chemicals that some companies use and can be damaging to the surrounding environment.
Our unique mixtures combine macro- and micro-nutrients, root growth stimulators, soil conditioners, beneficial biotics (both mycorrhizal fungi and rhizobacteria), and organic materials to cultivate the optimum natural growth environment.
Fertilization, Soil Application, and Deep Root Injection Services
Any tree located in either a residential or commercial landscape will benefit from fertilization. In other words, if your tree is not currently located inside of a forest, it will need help sourcing the nutrition necessary to thrive.
Fertilization services are critical for trees that:
- Have been affected by harsh environmental conditions such as heat and drought
- Are struggling to produce growth or recover from insects or disease
- Have been stunted by limited root space (i.e., parking lots, sidewalks, fencing)
- Have been affected or damaged by construction-related activities in the area
Fertilization services include:
- Soil conditioners that help break down heavily compacted soil
- Root stimulators delivered to promote more effective root systems
- A complete combination of balanced macro- and micro-nutrients – quantities are adjusted seasonally.
- Mycorrhizal fungi are naturally growing additions to the soil that form a symbiotic relationship with the tree’s existing natural root system to speed nutrient absorption, enhance the existing root system, and allow the tree to be more competitive
- Rhizosphere bacteria are beneficial bacteria that break down organic matter and promote nutrient absorption and tree immunity systems
- Nutrient application delivered 6-12 inches beneath the turf throughout the drip line to ensure balanced absorption and reduced turf competition

OAK WILT TREATMENT
As oak wilt is a systemic, vascular disease, the most effective treatments consist of injecting the infected trees with a fungicidal chemical. The only currently recommended fungicide is Alamo®, a formulation of the fungicide propiconazole. The fungicide is administered through holes drilled in the root flare of the infected tree and should only be applied by Texas Department of Agriculture Licensed Applicators.

STRESSED MAGNOLIA | AFTER
This after photo was taken June 27, 2024 of a magnolia tree after receiving multiple interventions to improve its health. In addition to a tree health care plan of a deep root fertilization with Biopack plus and Sea3 applied by our TDA licensed technician the owner also fixed the irrigation and cleared the root flare. The difference in health is beautiful.

FERTILIZATION
Our Tree Health Care Programs are designed to deliver the right nutrients at the right times throughout the year. We use the highest quality soil conditioners and fertilizers that are delivered at critical points throughout the seasons to optimize the growth and health of trees.

DEEP ROOT INJECTION SERVICES
At Texas Tree Surgeons our deep root injection services provides fertilization deep into the soil. Our unique mixtures combine macro- and micro-nutrients, root growth stimulators, soil conditioners, beneficial biotics (both mycorrhizal fungi and rhizobacteria), and organic materials to cultivate the optimum natural growth environment.

ROOT PRUNING POST AIR SPADING
To correct this improperly planted tree our Tree Health Care Technicians air spade to expose the root flare and to prune away girdling roots. You can learn more about how to properly plant a tree here.

GIRDLING ROOTS
This tree was planted too deep and has several girdling roots (roots that circle the tree and do no flare out) that left unmanaged would eventually kill the tree. After air spading our Tree Health Care Technicians are pruning the roots and adjusting the soil around the tree to expose the root flare to improve tree health.

INSPECTING FOR POSSIBLE DECAY
Sometimes issues with a tree aren't clearly visible on the outside so an arborist will need to inspect the interior. An arborist does this by probing with a small knife to see how extensive the decay in a region of a tree is. Arborists are able to use this information along with other signs to determine if there are potential structural issues or possible increased chances for failure.

MEASURING DBH
The best way to approximate the size of a tree is to measure their dbh, (diameter, breast, height). This enables our arborists to estimate the amount needed for Tree Health Care products or pricing for Tree Removal.
