River Birch Surface Roots Near Building: Do Not Cut—Add Sand, Prune Limbs Instead

Root Nature

River birch (Betula nigra) has fibrous, non-destructive roots. No documented structural damage.

Surface Root Management

• Do NOT cut roots—harms tree.
• Cover with ≤2 inches of sand only (clay smothers roots).
• Prune limbs rubbing building instead.

Longevity

Urban trees live shorter than wild, but proximity doesn't shorten life. River birch commonly planted near structures.
