Sitka Spruce (picea sitchensis)
£0.60
Britain’s most widely planted productive conifer. Extremely fast-growing (up to 1 m+ per year when young), highly tolerant of exposure and poor/wet soils, and delivers high timber yields for construction, packaging, fencing, pulp and paper. Easy to establish with good early growth; versatile and well-suited to upland and western sites.
Key growing conditions
- Grows best in full sun
- Moist to wet soils of poor to medium fertility; acid to neutral pH
- Prefers high rainfall (>900–1,000 mm per year) and maritime climates – best in northern and western Britain
- Highly tolerant of exposure; cold hardy but sensitive to late spring frosts and air pollution
- Avoid dry or shallow soils
- Bare-root: dormant season (typically November–April), avoiding frozen or waterlogged ground
- Dig a suitable hole or plant into prepared ground (ploughing/mounding common on wet sites)
- Position so the root collar is at soil level; firm gently and water if needed
- Plant at ≥2,500 stems per hectare (approx. 2 m spacing) for quality timber to limit coarse branching
- Give far more space for specimen or amenity trees (mature height often 40–55 m+)
- Weed control for the first few years until canopy closes (typically 15–20 years)
- Generally less palatable to deer than many other conifers, aiding establishment
- Minimal pruning required
- Rotations commonly 40–50 years in commercial stands
