Mr. Tree’s Pest and Disease Management program begins with meticulous diagnostics by ISA‑certified arborists who understand the unique pressures Portland’s temperate, rain‑soaked climate places on local species. During an on‑site evaluation, our team inspects foliage, bark, and root zones for early indicators of common regional threats—such as bronze birch borer, aphids, Sudden Oak Death, and anthracnose—while also sampling soil to detect nutrient imbalances that weaken natural defenses. Advanced tools like resistographs, pheromone traps, and digital microscopes allow us to pinpoint infestations or pathogens before they escalate into structural or aesthetic damage.

Once the culprit is identified, Mr. Tree deploys an integrated pest‑management (IPM) strategy that balances efficacy with environmental stewardship—a must in the ecologically sensitive Willamette Valley. We combine targeted, low‑toxicity treatments (including horticultural oils, systemic injections, and bio‑controls like predatory insects) with cultural practices such as selective pruning, aeration, and mulching to disrupt pest life cycles and improve tree vigor. For diseases, our arborists may prescribe trunk injections, fungicide drenches, or pruning protocols that remove infected tissue while maintaining canopy integrity; every recommendation aligns with Oregon State University Extension guidelines and Portland’s Urban Forestry regulations.

Ongoing monitoring is the cornerstone of our service. After initial treatment, Mr. Tree establishes a customized schedule of follow‑up visits—often timed to key life‑cycle stages of local pests or seasonal moisture peaks that favor fungal growth—to verify progress and adjust tactics as needed. Detailed digital reports, complete with photos and next‑step recommendations, keep homeowners, HOAs, and commercial property managers informed and compliant with city standards. From Lake Oswego to Gresham and across the Columbia in Vancouver, Washington, Mr. Tree delivers proactive, science‑backed pest and disease management that protects tree health, property value, and the broader Pacific Northwest ecosystem.
