Mr. Tree’s root‑management program begins with a comprehensive on‑site evaluation across Portland and surrounding communities—from Hillsboro to Gresham and north to Vancouver, Washington. ISA‑certified arborists use ground‑penetrating radar, pneumatic air‑spade excavation, and soil compaction meters to map critical root zones, identify girdling or invasive surface roots, and diagnose soil issues such as oxygen deprivation in Portland’s often water‑logged clay. This diagnostic phase pinpoints the root‑related causes of canopy decline, sidewalk heaving, or drainage problems while ensuring compliance with the City of Portland’s tree‑protection standards.

Armed with precise data, Mr. Tree tailors interventions that balance tree health with property safety. Where structural roots threaten foundations or utilities, our crews perform selective root pruning with sterilized tools, immediately sealing cuts to limit pathogen entry. For trees endangered by construction, we install high‑density polyethylene root barriers, erect mulch‑lined protection zones, and apply radial trenching with biochar‑enhanced backfill to improve aeration and water infiltration. Compacted soils under driveways and footpaths are remediated through vertical mulching or pressurized air‑injection, loosening the substrate without damaging fine feeder roots and restoring vital nutrient flow.

Long‑term vitality hinges on follow‑up care, so Mr. Tree provides custom maintenance plans that include calibrated deep‑root fertilization, periodic aeration, and root‑crown inspections timed to Portland’s seasonal moisture cycles. Detailed digital reports document every treatment and recommend future actions—whether additional pruning, cabling for stability, or soil pH adjustments—giving homeowners, HOAs, and commercial property managers a clear roadmap for sustainable tree health. With advanced diagnostics, environmentally responsible techniques, and decades of local expertise, Mr. Tree ensures your trees’ roots remain strong, non‑invasive, and resilient for generations to come.
