Gravel Fill Kills Oak Roots: Remove Fill, Water Deeply

4–5 Inches of Gravel = Root Suffocation

Fill over roots cuts oxygen. 4–5 in. of gravel kills most roots in the zone. Roots extend 1.5× canopy spread.

Immediate Actions

• Remove all gravel from around trunks (keep driveway gravel if immovable).
• Water 1 in. every 3 days to support surviving roots.
• Expect limb dieback; deep watering may save the trees.

Never add fill over tree root zones.
