Protecting Tree Roots During Construction Near Lime Trees

Building 5 Meters From Mature Limes: Root Risk Assessment

At 5 meters (≈16 ft) from 50-ft lime trees, your foundation excavation (2 m deep) is likely outside the critical root zone, which typically extends to the dripline (canopy edge). Most roots are in the upper 12–18 inches of soil.

The Real Danger: Soil Compaction

Heavy equipment, material storage, and foot traffic over the root zone compact soil, crushing roots and reducing oxygen—causing canopy dieback years later. This is far more damaging than the trench itself.

Mandatory Protection Plan

• Install sturdy temporary fencing at the dripline before any work begins.
• Prohibit all traffic, parking, and storage inside the fence.
• Route equipment access away from trees.
• If roots are exposed during excavation, cover immediately with damp burlap and backfill promptly.

Monitor trees for 3–5 years post-construction; provide supplemental water during droughts.
