Pruning Colorado Blue Spruce Branches Touching a Deck

Safe to Prune

Removing rubbing/overhanging limbs won't harm tree if ≤50% crown retained.

Proper Cut Technique

• Three-cut method for limbs >1″: Undercut 12″ out, top cut 1″ beyond, final cut outside branch collar.
• Angle: 45–60° to branch bark ridge.
• Preserve branch collar (swollen base) for decay prevention.
• No wound paint. Spruce seals with sap.

Key Takeaway

Prune conflicting spruce limbs correctly using three-cut method and branch collar preservation. No sealant needed.
