Protect Your Trees with Certified Arborists & Tree Health Care in Raleigh, NC
A struggling tree usually has a cause — and often a cure. Heartwood's board-certified arborists diagnose disease, pests, and decline with real science, then treat and protect your trees so you don't lose them.
Tree Health Care, Backed by Science
We don't just cut trees — we keep them alive and thriving. Every service starts with a real diagnosis by a certified arborist.
A Tree Doctor, Not a Tree Cutter
Heartwood exists because too many trees are cut down that could have been saved. When a tree looks sick, most companies see a removal. We see a patient.
Our practice is led by an ISA Board-Certified Master Arborist — the highest credential in the field — and everything we do is grounded in real diagnostics: soil tests, root-collar excavations, canopy analysis, disease identification. We treat, feed, cable, and protect trees, and we'll always tell you honestly when a tree genuinely can't be saved. Since 2011 we've assessed and treated over nine thousand trees across the Triangle, and kept a great many of them standing.

Why a Board-Certified Arborist Is Worth It
Tree health is a science. Here's why the Triangle's homeowners trust their most valuable trees to a certified arborist.
The Highest Credential
A Board-Certified Master Arborist represents the top of the ISA's certification ladder — years of study, testing, and proven expertise.
Real Diagnosis
We identify the actual cause of decline — disease, pest, soil, or stress — instead of guessing or defaulting to removal.
Trees Saved, Not Removed
Our whole aim is to keep your trees alive. A treatment plan is almost always cheaper than losing a mature tree.
Science-Based Treatment
Soil tests, root-collar excavation, and targeted, responsible treatments — the right intervention, not a one-size-fits-all spray.
Fully Insured & Bonded
$2M liability plus workers' comp, so you and your property are completely protected during any work.
Honest Recommendations
We tell you the truth about your tree — including when it truly can't be saved. No upselling, no scare tactics.
The Difference Between Cutting and Caring
A certified arborist approaches a struggling tree the way a doctor approaches a patient — diagnose first, treat second.
Diagnose the Real Cause
We examine canopy, trunk, roots, and soil to find the actual problem — not just the visible symptom.
Prescribe, Don't Default to Removal
Most declining trees can be treated. We prescribe the specific care your tree needs, and remove only as a last resort.
Treat With the Right Science
Targeted, responsibly-applied treatments and deep-root feeding — the correct intervention for the specific diagnosis.
Monitor and Protect
We follow up to make sure the tree responds, and set up proactive care so small problems never become removals.
From Worried to Well
Getting a struggling tree the right care is straightforward when a certified arborist leads it.
Book an Assessment
Tell us what you're seeing — dropping leaves, dieback, fungus, a lean — and we'll schedule an on-site evaluation.
On-Site Diagnosis
Our arborist assesses your tree thoroughly — canopy, trunk, roots, and soil — to identify the real cause.
A Clear Care Plan
You get a written diagnosis and honest recommendations, whether that's treatment, deep-root care, cabling, or monitoring.
Treat & Follow Up
We carry out the plan and check back to make sure your tree is responding and on the road to recovery.
What 'Board-Certified Master Arborist' Actually Means
Anyone can call themselves a tree expert. A Board-Certified Master Arborist is different — it's the highest level of certification the International Society of Arboriculture offers, held by only a small fraction of arborists. It requires years of professional experience and passing a rigorous examination covering tree biology, diagnosis, soil science, and risk assessment.
What it means for you is simple: the person diagnosing your tree genuinely understands how trees live, get sick, and heal. When your most valuable trees are at stake, that depth of expertise is exactly what makes the difference between losing a tree and saving it.

- ✓Rigorous exam + years of field experience

The Triangle Trusts Us With Its Trees
Our two big willow oaks were dropping leaves in July and I was sure we'd lose them. Heartwood's arborist did an actual assessment — soil, roots, canopy — diagnosed a fixable issue, and set up a treatment and deep-root feeding plan. A year on, both trees are thriving. They saved trees three other companies just wanted to remove.
We noticed strange fungus and dieback on a heritage tree and Heartwood came out, identified the disease precisely, and explained exactly what could and couldn't be done — honestly. Their treatment plan halted it. It is such a relief to work with a real certified arborist instead of a guy trying to sell a removal.
A huge oak with a split trunk was leaning over our house and we assumed it had to come down. Heartwood's arborist assessed the risk properly, installed cabling and bracing, and now it's safe and staying. Their tree risk report was thorough and gave us total peace of mind. True experts.
We manage a property with dozens of mature trees and Heartwood is on an annual health plan with us now. Proactive assessments, early pest catches, and deep-root feeding have kept every tree healthy and headed off problems before they became removals. The science-based approach genuinely pays for itself.
Book a Tree Health Assessment
Dropping leaves, dieback, fungus, pests, or a tree you're just not sure about — let a certified arborist take a proper look and tell you honestly what's going on and what can be done.
Tree Health Questions, Answered
Can a sick or dying tree actually be saved?
Very often, yes — far more often than people assume. Many trees that look like they're dying are actually suffering from something treatable: a soil or root problem, a manageable pest, a fungal disease caught in time, or simple stress. The key is a real diagnosis by a certified arborist before anyone reaches for a chainsaw. We'll assess your tree honestly and tell you whether it can be treated or whether it genuinely needs to come down.
What does a tree health assessment involve?
Our arborist evaluates the whole tree and its environment: the canopy for dieback and discoloration, the trunk and branches for wounds, cracks, and decay, the root collar and roots, and the soil conditions. We identify any diseases or pests present and consider the tree's overall context. You then get a clear written diagnosis with honest recommendations — treatment, deep-root care, cabling, monitoring, or, when necessary, removal.
What is a Board-Certified Master Arborist?
It's the highest level of arborist certification offered by the International Society of Arboriculture (ISA), held by only a small percentage of arborists. It requires extensive professional experience plus passing a rigorous exam covering tree biology, diagnosis, soil science, and risk assessment. In practice it means the person caring for your trees has genuine, tested expertise in how trees live, get sick, and recover — not just experience running a chainsaw.
My tree has fungus or mushrooms on it. Is it dying?
Not necessarily, but it's worth having looked at. Some fungi are harmless, while others — particularly mushrooms growing at the base or on the trunk — can indicate internal decay that affects the tree's structure and safety. The only way to know is a proper assessment. Our arborist can identify what the fungus is, what it means for your specific tree, and whether treatment, monitoring, or action is needed.
What is cabling and bracing, and when is it needed?
Cabling and bracing are structural supports installed in a tree to reduce the risk of a weak limb or split trunk failing. They're often used to save a valuable mature tree that has a structural flaw but is otherwise healthy — an alternative to removal. During a risk assessment we can tell you whether cabling would make your tree safe to keep, and install it properly if so.
Are you licensed, insured, and certified?
Yes on all three. Our practice is led by an ISA Board-Certified Master Arborist, we carry $2M in liability coverage plus workers' comp, and we're bonded. Whether we're diagnosing a tree, treating a disease, or installing cabling, you're working with genuine credentialed expertise and full protection. We're always glad to provide proof of insurance and certification.
