Treehouse Attachment in Cedar: Nails vs. Lag Bolts

Small nails in cedar won't kill the tree—cedar resists decay. But 1–1.5″ nails in 1″ lumber lack holding power. Use 3″+ galvanized lag bolts with washers for structural connections. As the tree grows, bolts will embed; boards may push off.

Lag bolts are stronger, longer-lasting, and cause minimal additional damage. Drill pilot holes to avoid splitting.
