Frequently Asked Questions

Typically, annual or biannual services work best for maintaining soil health and monitoring pests. We recommend a seasonal plan based on species and site conditions.

Yes—we work with conifers, maples, ornamentals, fruit trees, and shrubs native to our region, adapting treatments as needed.

Absolutely. We use environmentally responsible products and application methods to ensure safety for families and pets.

Costs depend on property size, number of trees, and specific treatments. We provide a clear treatment plan and cost estimate after the assessment.

Regular maintenance — pruning, removal, cleanup — reacts to what trees need today. Plant Health Care is proactive: scheduled soil care, pest monitoring, disease prevention, and structural inspections that catch problems before they become emergencies.

Common warning signs include thinning canopy, dieback at branch tips, early leaf drop, sap or sawdust on the trunk, mushrooms at the base, or unusual leaf color. An ISA Certified Arborist evaluation is the most reliable way to confirm tree health.

Yes — and often more than young trees. Mature trees are more vulnerable to soil compaction, drought stress, and pest pressure. A PHC program extends their useful life and reduces the chance of sudden failure.

Most properties see noticeable improvement in canopy fullness and color within one full growing season. Soil health and structural improvements compound over 2 – 3 years.

Yes. Healthy trees with strong root systems and well-spaced canopies survive wind events significantly better than stressed or untreated trees. Structural pruning is part of every PHC program.

No. Fertilization is one part of PHC. A full program also includes soil testing, pest scouting, disease prevention, mulching guidance, structural recommendations, and scheduled inspections.

Standard programs include 2 – 4 scheduled property visits per year, with seasonal written reports. High-value or hazard-prone properties can be scheduled more frequently.

Yes. PHC includes monitoring for common Pacific Northwest pests — aphids on maples, tent caterpillars, scale, bronze birch borer, and others — with targeted treatment when scouting confirms it is needed.

What Does a Plant Health Care Program Cost?

Plant Health Care (PHC) is priced based on the number of trees, their size, and the treatment frequency. A typical residential PHC program is far less expensive than a single emergency removal — and pays for itself within one prevented hazard event.

Program TierTypical Annual Range
Single high-value specimen tree$200 – $500
Small residential property (2 – 5 trees)$400 – $900
Medium residential property (5 – 10 trees)$900 – $1,800
Large estate or HOA common area$1,800 – $5,000+

PHC includes soil evaluation, fertilization, pest and disease monitoring, scheduled inspections, and written seasonal reports. Compare this to a single emergency removal — often $1,800 – $3,500 — and PHC often pays for itself within one prevented hazard.

The Pacific Arboriculture Process

Every job follows a clear, step-by-step process so homeowners and property managers know exactly what to expect from the first phone call to final cleanup.

  1. 1Site & Soil EvaluationAn ISA Certified Arborist inspects each tree, samples soil pH and nutrient levels, and identifies pest, disease, or environmental stress signs.
  2. 2Custom Care PlanA written plan is built for the property — species-specific fertilization, pest monitoring schedule, mulching guidance, and any structural pruning recommendations.
  3. 3Targeted TreatmentsTreatments are applied at the right time of year — dormant oil in late winter, root-zone fertilization in early spring, pest interventions when scouting confirms need.
  4. 4Ongoing MonitoringScheduled property visits track tree response, catch new pests early, and adjust the plan as trees mature or weather patterns shift.
  5. 5Seasonal ReportsWritten updates summarize what was found, what was treated, and what to watch for in the coming season.
  6. 6Long-Term Health TrackingPhoto records and inspection notes build a multi-year health history for each tree — useful for insurance, real estate disclosures, and replacement planning.

What Customers Are Saying

★★★★★

"Jared and his crew arrived a few minutes ahead of schedule and were very professional. Jared was great in answering questions and listening while explaining how much to cut off the trees. He pruned both the Magnolia and Pine tree. An enormous limb the size of the trunk broke off the Pine during a storm. Jared was able to clean up the jagged break to prevent disease and insects entering the tree, along with pruning some limbs and removing all the dead branches. The trees now look awesome — Pacific Arboriculture comes highly recommended."

"Great experience from start to finish. Fast response with a solid bid soon after calling. Brandon and the rest of the crew removed a couple of trees, ground a stump, and did some awesome work pruning a paper bark, maple, and black pine (which included the rescue of a baby raccoon). That nasty looking pine now looks absolutely amazing. Great job with cleanup to top it off. Highly recommend."

"A large project consisting of 9 trees with work ranging from stump grinding, pruning, and fruit tree care. Every step of the process was amazing. It is very telling how passionate everyone is about tree health. So much learned along the way. The team was thorough with everything and surprisingly detailed with the cleanup — not a leaf or twig was left behind. Pacific Arboriculture will be the call for future tree work, and Caren's dad plans on hiring them too."
