Blue Spruce Pruning & Fertilizing: Less Is More

Spruces Rarely Need Shaping

Blue spruce naturally maintains dense, pyramidal form. Prune only:

• Wayward branches outside the silhouette.
• Dead/damaged wood.
• Wait a few years to see mature shape.

Fertilizer

• Only if foliage thins.
• 1 lb 10‑10‑10 per inch trunk diameter, early April (before July 15).
• Water in; avoid late‑season feeding (winter injury risk).
