 Plant Health Care (PHC)

Scientific Tree Care for Highlands, Cashiers & Western North Carolina

Western North Carolina’s mountain forests are home to some of the most valuable and sensitive trees in the Southeast. Protecting them requires more than simple guesswork — it requires scientific diagnostics, precise treatments, and a trained arborist who understands soil biology, tree physiology, and regional pest pressures.

SkyLine Arbor offers advanced Plant Health Care (PHC) built on formal education, laboratory-backed testing, and years of field experience from Georgia to New York.

Comprehensive Soil Testing & Diagnostics

Healthy soil means healthy trees.

Before any treatment plan is created, we evaluate the root zone — the true foundation of tree health.

Our soil testing examines:

pH balance

Macro & micronutrient levels

Organic matter content

Lead contamination

PCBs

Glyphosate residues

Soil structure & compaction indicators

You receive a clear, easy-to-understand report explaining what’s happening in the soil, how it affects your trees, and the exact steps needed to correct deficiencies.

Perfect for:

Declining trees

New homeowners

High-value hardwoods

Mountain properties with disturbed soils

Heavily landscaped areas around homes & estates

---

Soil Injections & Root-Zone Treatments

Targeted soil treatments help correct underlying deficiencies, restore vitality, and support long-term tree health.

Our services include:

Nutrient Injections

Directly replenish essential nutrients missing from your soil profile.

Pest-Control Soil Treatments

Safe, regulated applications for pests affecting the root zone.

Mycorrhizal Fungi Treatments

Rebuild beneficial soil biology destroyed by construction, compaction, or erosion.

Root-zone enhancement for stressed trees

Improves nutrient uptake, vigor, and resilience.

These treatments are ideal for mountain properties where soil disturbance, rocky terrain, or thin organic layers limit natural nutrient cycles.

---

Prescription Fertilization Programs

Based entirely on your soil test results — not guesswork.

We create custom fertilizer programs designed for each tree or planting area.

Your prescription may include:

Slow-release nutrients

Micronutrient blends

Iron or manganese supplements

Biostimulants

Soil conditioners

Organic matter amendments

Beneficial fungi applications

This ensures your trees get exactly what they need, improving growth, foliage color, resilience, and overall vitality.

Tree Injections (Trunk Injection Systems)

Precise. Targeted. Highly effective.

As an NC Licensed Pesticide Applicator, SkylineArbor uses professional Arborjet & Quick-Connect systems to deliver treatments directly into the tree’s vascular tissue.

Injection treatments address:

Hemlock Woolly Adelgid (HWA)

Emerald Ash Borer (EAB)

Fungal & bacterial diseases

Borer insects & chewing insects

Nutrient deficiencies

Tree decline from stress or soil imbalance

Preventative protection for legacy trees

Benefits of injection treatments:

No spray drift

No contamination of water, soil, or pollinator habitats

Fast uptake

Long-lasting control

Ideal for mountain homes, lakefronts, gardens & sensitive landscapes

---

Tree Health Assessments

A full health evaluation includes:

Structural assessment

Signs of decline or stress

Disease & pest inspections

Root zone evaluation

Soil condition review

Risk identification (lean, cracks, decay, weak unions)

Treatment or preservation recommendations

If a tree can be saved — we create the plan.

If it cannot — we provide honest guidance and safe removal options.

Why Plant Health Care Matters in the NC Mountains

Trees in Highlands & Cashiers face unique stresses:

Thin, acidic mountain soils

Steep slopes & erosion

Heavy rain saturation followed by drought

Construction damage

Root restriction around homes

Pest pressures (HWA, borers, scale, adelgids)

Nutrient-poor, rocky ground

Sudden environmental changes at elevation

Good PHC protects:

High-value hardwoods

Specimen trees

Scenic mountain views

Property investments

Older landscapes & legacy trees

Lakefront & ridge-top properties

Your home may be new — but the trees around it have been growing for decades or centuries.

PHC preserves that legacy.
