Colorado Spruce (Picea pungens) are a common choice in Southern Alberta because they handle the region’s tough conditions better than many other evergreens. A very hardy evergreen, truly built for Canadian living.
 
Growth 1-2ft/year
Will mature to around 40-60ft
Spread 10-20ft
 
Why They Do Well Here
Cold Hardy: Rated to handle Zone 2–3, so Alberta’s winters (even those -40°C nights) are no problem.
Drought Tolerant (Once Established): They’ll handle our hot, dry summers better than some other conifers, though they grow best with some supplemental water in the first few years.
Wind & Shelterbelt Use: Dense year-round foliage makes them excellent for windbreaks and privacy screens.
Growth & Appearance
Shape: Symmetrical, classic Christmas tree form with dense branches to the ground when young.
Color: Needle color can range from standard green to striking silvery-blue (often marketed as “blue spruce”). We have both phenotypes.
Size: Typically 30–60 ft (9–18 m) tall and 10–20 ft (3–6 m) wide in southern Alberta conditions, but slower growing here due to our shorter season — expect 8–12 inches of growth per year.
Planting Tips for Southern Alberta
Best Planting Time: Early spring or Fall, so roots can establish in cool soil.
Soil: Tolerates a range, but prefers well-drained loam. Heavy clay needs good planting technique to avoid root rot.
Sun: Full sun is best — at least 6 hours per day.
Spacing: For shelterbelts, stagger rows and, space 10–14 ft apart; for ornamental planting, give them room to spread without crowding.
Watering: Deep soak once a week in the first 2–3 years; after that, they’re low-maintenance. Also see "tree care guidelines" page for more indepth post-planting water guidelines.
