Tree Trunk and Root Damage from Sewer Excavation

Assessing Injury

• Bark loss ¾ around trunk: high mortality risk. Cambium likely severed.
• Exposed roots: clean-cut damaged roots; cover with soil.

Immediate Steps

1. Trim loose bark.
2. Spray wound with Merit (borer prevention).
3. Water 1 inch/week deeply.
4. Document damage; notify municipality in writing for liability.

Outcome

Tree may survive with crown dieback. Conifers compartmentalize better than hardwoods. Monitor for 1 year.
