School Oak Root vs. Gym Floor: Cut ≤25 % & Fertilize

Measure dripline circle. Cut roots only where they hit the foundation—keep cut area ≤25 % of circle. Fertilize: 1 lb 10‑10‑10 per inch DBH, watered in. Some branch dieback likely; tree survives.

Cut Close to Building

Minimizes root loss. Do not remove more than necessary.
