Norway spruce

Sun

Full sun; tolerates light shade, but develops a denser crown in sun.

Water

Moderate; keep young trees evenly moist. Established trees tolerate brief dry spells but struggle with prolonged drought and hot, dry summers.

Soil

Moist, well-drained, preferably acidic to neutral soil. Tolerates clay if drainage is adequate; avoid waterlogged ground and very dry, shallow soil.

Height

60-100 ft (18-30 m), sometimes taller with age

Spread

25-40 ft (7.5-12 m)

Foliage

Evergreen. Dark green, stiff, pointed needles arranged singly around the shoots; older branches carry distinctive drooping branchlets. Long, hanging cones mature brown.

Growth

Fast when young, often 1-3 ft (0.3-0.9 m) a year in suitable conditions.

Care needed

Low

• Deer resistant
• Cold hardy
• Wildlife

Northern hemisphere months. In Australia, shift them by six.

Growth rate

Fast

• Plant with the root flare at ground level, well away from buildings, overhead wires and other trees that need sun.
• Water deeply during dry spells for the first two or three growing seasons; do not leave the root ball standing in water.
• Spread 2-3 in (5-8 cm) of organic mulch over the root area, keeping it clear of the trunk.
• Avoid routine feeding; use a soil test if growth is poor or needles become unusually pale.
• Stake only if the root ball moves in wind, and remove supports once the tree is securely rooted.

Pruning. Prune dead, damaged or competing leaders in late winter or early spring, retaining one upright leader. Avoid topping or cutting into bare old wood, which usually will not produce replacement growth.

Late winter

Inspect the leader and branches for storm damage; make only necessary corrective cuts.

Spring

Plant while soil is workable and moisture is reliable; water thoroughly and mulch.

Late spring

Check new shoots for aphids and examine older needles for yellowing or premature shedding.

Summer

Water young trees deeply during dry weather and check for spider mites if needles become finely speckled.

Autumn

Refresh mulch without burying the root flare, and water if the soil is dry before winter.

Winter

Keep de-icing salt away from the root zone and avoid knocking ice from frozen branches.

• Use as a specimen on a large lawn, allowing room for the broad lower branches.
• Plant in a spacious shelterbelt or evergreen screen, allowing for mature spread rather than crowding trees together.
• Combine with birches or rowans for contrasting bark, foliage and seasonal colour.
• Use as a dark evergreen backdrop to woodland-edge shrubs and spring-flowering plants, outside its densest root competition.

Garden styles it suits: Scandinavian, Grand estate, Woodland, Winter interest, Mountain lodge and Traditional.

Plant it with: Silver birch, Rowan, Witch hazel, Rhododendron, Christmas fern and Hosta.

Wildlife: Dense branches provide shelter and nesting sites for birds. Seeds feed seed-eating birds and small mammals; native conifers may support a wider range of local specialist wildlife outside its European range.

• Spruce spider mites cause fine pale stippling and bronzing, especially in dry conditions. Confirm mites by tapping a branch over white paper; reduce drought stress and use a labelled treatment if damage is substantial.
• Needle-cast fungi can cause spotting and premature loss of older needles. Improve airflow, avoid wetting foliage and obtain a diagnosis before considering fungicides.
• Cytospora canker can kill branches, often with resin around affected areas. Reduce drought and root stress, and prune dead branches in dry weather; fungicides do not cure established cankers.
• Waterlogging and root decay cause weak growth, yellowing and possible instability. Correct drainage where practical and have a qualified arborist assess trees with decay or movement at the base.

Not known to be toxic to cats, dogs, horses or people. Swallowed needles can irritate the mouth and digestive tract, and resin may irritate sensitive skin; discourage pets and children from chewing needles, cones or bark.

Where it spreads. Naturalized in parts of the northeastern and north-central United States and eastern Canada, where seedlings can establish beyond planted trees. Spread and ecological impact vary locally; check regional guidance before planting beside natural woodland.

• White spruce (Picea glauca)

  Usually has shorter, often blue-green needles and much smaller cones; it lacks the strongly hanging branchlets typical of mature Norway spruce.

• Serbian spruce (Picea omorika)

  Has a narrower crown and flattened needles with two conspicuous white bands beneath; Norway spruce needles are four-sided and green around the surface.

• European silver fir (Abies alba)

  Has flat needles with white bands beneath and upright cones that break apart on the tree. Norway spruce has pointed, four-sided needles and hanging cones.

Norway spruce refers to its northern European occurrence; Picea is the Latin name for spruce, while abies is the Latin name for fir.

Propagation. Grow the species from seed, usually after a period of cold, moist stratification. Named cultivars are generally propagated by cuttings or grafting to preserve their characteristics.
