Poplar Roots and Neighbor's Foundation/Septic: Barrier Option

Neighbor wants your poplars cut—roots threaten foundation and septic.

Root Reality

• Roots spread 1.5× canopy width.
• Unlikely to reach neighbor’s foundation unless very close.
• Septic lines: roots enter only if pipes leak/crack.

Solution

• Install root barrier (HDPE/plastic) vertically along property line to deflect roots.
• Barrier depth 24–36″.
• Share info: root barrier specs.

Bottom Line

Poplars probably not the cause. Root barrier solves neighbor’s concern without cutting trees.
