Conifer Root Lifting Pathway: Root Barrier Fix

15-ft conifer lifting cement path. Asked if cutting 5-in root harms tree.

The expert said: depends on trunk-to-sidewalk distance. Farther = better survival. Dig 6-ft trench 1–2 ft from sidewalk, 2–3 ft deep, 6–12 in wide. Cut all roots. Line with geotextile (Typar) from bottom to just below surface. Backfill. Barrier prevents regrowth toward sidewalk. Check nursery for fabric.
