What Does An Arborist Do?
An arborist is a specialist in the care, cultivation, and botany of individual trees. Here are the core services our certified arborists provide.
Tree Health Evaluations
Diagnosing structural issues, diseases, insects, nutritional deficiencies, and general plant stress.
Risk & Hazard Assessments
Systematically identifying structural compromises, cavities, root cracks, and estimating tree failure probabilities.
Arborist Consultations
Providing expert testimony and evaluations for construction protection, zoning compliance, and neighbor concerns.
Pruning & Removal Plans
Designing custom tree care blueprints to save compromised trees and extend canopy life cycles.
Permit & Municipal Reports
Authoring formal arborist reports required by local cities to permit structural tree removals or heavy pruning.
Soil & Root Management
Inspecting root flares, managing soil compaction, and applying deep root fertilization to nourish root structures.
Common Tree Health Issues
Trees in the Pacific Northwest are susceptible to various fungal, insect, and structural issues. Here are common warning signs.
Bracket Fungi & Decay
Mushroom-like bracket fungi growing at the trunk base or root flare signal internal wood rot and decay.
Insect Infestations
Aphids, scale, and wood-boring beetles can colonize and slowly consume vital vascular layers.
Foliar Spotting & Rust
Fungal leaf spots, rusts, and needle cast cause premature defoliation and general growth suppression.
Soil Compaction
Heavy traffic, lawns, and concrete crush vital air pockets in soil, starving root systems of oxygen and water.
Girdling Roots
Roots that grow in a circular pattern around the base of the trunk can choke and cut off water/nutrient flows.
Environmental Stress
Severe droughts, record winter freezes, or chemical runoffs can shock root systems and cause canopy dieback.
Tree Assessments & Inspections
Before recommending any tree service, our certified arborists perform a thorough visual inspection from the root flare up to the crown tips. We look for decay indicators, inspect branches, evaluate trunk structure, and test soil condition.
Whether you need a structural tree inspection in Tacoma, permit evaluations in Puyallup, or a comprehensive health check in Everett, we deliver detailed reports to help you make informed decisions.
