y and wind-tough, this evergreen thrives where winters bite and summers are dry. Use one as a statement tree or line several for a living windbreak and privacy wall that looks crisp in every season.

Colorado Blue Spruce Care

Give this tree full sun for best color, ideally 6–8 hours daily. Plant in well-drained soil with a slightly acidic to neutral pH (about 6.0–7.5); avoid constantly wet or heavy clay sites. Water deeply the first 1–2 years, about once per week, adjusting so the root zone dries slightly between soakings; once established, water during extended droughts.

Apply a 2–3 inch layer of mulch over the root zone, keeping it a few inches off the trunk. Feed in early spring only if a soil test indicates need, using a slow-release, evergreen-formula fertilizer; do not fertilize after midsummer.

Prune in late winter to remove dead or rubbing branches; for light shaping, tip-prune new growth in late spring without cutting back to bare wood. Hardy in Zones 2–7; color holds best with full sun and good airflow. Monitor for spider mites in hot, dry spells and for needle cast or canker in humid regions; improve airflow and avoid overhead watering.

Colorado Blue Spruce Spacing

As a specimen, allow at least 15–20 feet of width and plant 20–30 feet from buildings or large trees. For a windbreak or privacy row, space 12–16 feet on center. Keep 8–10 feet from walks, drives, and property lines to accommodate the lower limbs. Do not plant under power lines.

Staking is typically unnecessary; in very windy sites, stake for the first season only.
