Norfolk Island Pine Roots: Safe at 5–6 Meters

No Foundation Risk at That Distance

Norfolk Island pine (Araucaria heterophylla) develops a prominent taproot with limited lateral spread. At 5–6 meters (16–20 ft) from the house, roots will not threaten foundations.

Root Characteristics

• Deep taproot for stability.
• Sparse, non‑aggressive lateral roots.
• Unlike ficus or willow, not known for structural damage.

Caveat

In containers or restricted soils, roots may circle—but in open ground at this distance, zero concern.
