Post Hole Near a 100-Foot Pine: Root Cut Is Harmless

One Root Cut = No Problem

Digging a 2-ft deep, 12-inch wide post hole 10 ft from a massive pine severed a large root. The owner worries about tree health and stability.

Why It's Fine

• Root systems are redundant; one root is a tiny fraction of the total.
• No measurable impact on water uptake or anchorage.
• Trenching (many roots cut) is damaging; a single hole is not.

Proceed with the fence. The pine won't notice.
