200-year-old live oaks for a veteran homeowner
- Problem
- Soil and mulch built up against the trunks, landscaping crowding the root zone, and years of compaction.
- Assessment
- Air-spade excavation showed healthy structural roots, plus two girdling roots that would tighten as the trees grew.
- Reasoning
- Live oaks evolved as forest trees. Restoring forest-floor soil conditions does more for them than repeated fertilizer.
- Work performed
- Removed the girdling roots, decompacted the drip line, injected the soil and laid whole-tree arborist chips.
- Result
- Root flares exposed and protected, with a soil program in place and re-inspection scheduled.
- Methodology
- Air-spade root-collar excavation · ANSI A300 soil and root management
