Ash Tree Roots Damaging Driveway: Root Barrier Solution

Ash tree roots (exposed 8 ft from trunk) have cracked driveway. City already cut 1/3 of roots. Owner asks if they can cut more or must remove tree.

Guidelines

• Up to 25% root loss is a guideline; additional cutting depends on proximity to trunk.
• Cut roots cleanly along driveway, install root barrier (18″ deep).
• Fertilize remaining roots with 10-10-10 (1 lb/inch trunk diameter) to stimulate regrowth.
• Monitor; if tree declines, remove later.
