Norfolk Island Pine Near Foundation: Root Risk at 2 Feet

Removing a 15-Ft Norfolk Pine 2 Ft from House

Norfolk Island Pine (Araucaria heterophylla) roots will far exceed a 2-ft clearance. At 15 ft tall, root spread is likely 10-15 ft radius.

Risks

• Foundation pressure/cracking.
• Patio heaving.
• Moisture depletion under slab.

Action

Remove it now while manageable. Replace with a sidewalk-approved tree:

• Japanese tree lilac (Syringa reticulata)
• Serviceberry (Amelanchier)
• Kousa dogwood (Cornus kousa)
• Redbud (Cercis canadensis)

If Keeping (Not Advised)

• Install root barrier 3 ft deep, 3 ft from foundation.
• Monitor foundation annually for cracks.
• Expect eventual conflict.

Sidewalk trees are bred for confined spaces; Norfolk Pine is not one of them.
