What You Get With Our Tree Health Care Service
Accurate Diagnosis
We identify the specific issue — not just the symptoms. Whether it's EAB, verticillium wilt, girdling roots, or lightning damage, the treatment depends on getting the diagnosis right.
Written THC / PHC Care Plan
You receive a written assessment and multi-year Tree Health Care or Plant Health Care plan with clear recommendations and cost estimates — following ISA best management practices.
Liability Documentation
For trees near structures, our written ISA Tree Risk Assessment provides documentation that can protect you in the event of a claim.
Proactive Approach
Catching and treating problems early is almost always cheaper than removal. Regular THC assessments from our Skilled Trades Ontario Registered arborists save you money long-term.
Our Process
Visual Inspection
Our ISA Certified Utility Arborists assess the crown, trunk, root flare, and soil — looking for discoloration, dieback, cracks, cavities, and other PHC indicators.
Diagnosis
We identify the specific disease, pest, or structural issue and classify it within an ISA-standard THC risk framework.
Care Plan
We recommend specific treatments — pruning, fertilization, pest management, cabling, or removal — as part of your written Plant Health Care program.
Follow-Up
We schedule follow-up visits to monitor response to treatment and adjust the PHC plan as needed over multiple growing seasons.
Frequently Asked Questions
What is Tree Health Care (THC)?
Tree Health Care (THC) is a systematic, science-based approach to maintaining tree health — combining regular monitoring, diagnosis, and targeted treatment rather than reactive removal. It's the same approach used by ISA Certified arborists and Skilled Trades Ontario Registered professionals.
What is Plant Health Care (PHC)?
Plant Health Care (PHC) extends tree care principles to your entire landscape — shrubs, ornamentals, and soil health included. Our PHC programs address the whole ecosystem of your property, not just individual trees.
My tree has a fungus on it — is it dying?
Not necessarily. Some fungi (like shelf fungi) are indicators of internal decay, while others are harmless. A professional THC assessment is needed to evaluate severity and risk.
Can a tree recover from Emerald Ash Borer?
If caught early enough, EAB-infested ash trees can be treated with systemic insecticide (TreeAzin) that has good efficacy. However, trees that have lost more than 30–50% of their crown are generally beyond recovery.
What's included in a risk assessment?
Our risk assessments follow ISA Tree Risk Assessment standards. We evaluate likelihood of failure, likelihood of striking a target, and consequence of failure — producing a written report with specific recommendations.
