Fraser fir

Sun

Full sun to partial shade; light afternoon shade can help in warmer locations.

Water

Keep soil evenly moist but never waterlogged, especially during establishment and dry summers.

Soil

Acidic, humus-rich, well-drained soil; avoid chalk, compacted clay and sites with standing winter water.

Height

30-50 ft (9-15 m)

Spread

10-25 ft (3-7.6 m)

Foliage

Evergreen. Short, soft, flattened, dark green needles with two broad silvery-white bands beneath; aromatic when crushed. Upright purple cones mature brown and break apart on the tree.

Growth

Slow to moderate, depending on moisture and summer temperatures.

Care needed

• Cold hardy

Growth rate

Slow

• Plant with the root flare at soil level, allowing space for the mature lower branches.
• Water deeply during dry spells for the first few growing seasons; continue during drought once established.
• Spread 2-3 in (5-8 cm) of organic mulch over the root zone, keeping it clear of the trunk.
• Avoid routine heavy feeding; use a soil test before applying fertiliser.
• Keep vehicles, paving work and repeated foot traffic away from the shallow root zone.

Pruning. Little pruning is needed. Remove dead or damaged branches promptly; make any light shaping cuts in late winter or early spring, retaining one main leader and avoiding cuts into bare old wood.

Early spring

Plant once the soil is workable, provided it is not waterlogged; water thoroughly.

Spring

Check the trunk and branches for white, woolly adelgid colonies and inspect new growth for distortion.

Late spring

Renew mulch without piling it against the trunk.

Summer

Check moisture below the mulch and water deeply during dry weather.

Autumn

Water before the ground freezes if the season has been dry.

Late winter

Inspect for storm damage and remove broken branches without cutting back the main leader.

• Use as a single specimen on a spacious lawn, leaving its lower branches intact.
• Plant among deciduous trees at a woodland edge for year-round structure.
• Combine with acid-loving shrubs and ferns in a cool, moist garden.
• Use a loose group on a large property to frame views and provide winter greenery.

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

Plant it with: Rhododendrons, Mountain laurel, Highbush blueberry, Foamflower, Christmas fern and Canadian hemlock.

Wildlife: Dense branches provide shelter and nesting cover for birds. Seeds are eaten by birds and small mammals, and deer may browse young trees.

• Balsam woolly adelgid: white woolly colonies, swollen shoots and crown decline need prompt assessment by an arborist; treatment of small trees may be possible with appropriately timed, locally approved products.
• Phytophthora root rot: yellowing, wilting and dieback are favoured by wet soil. Improve drainage before planting; badly affected trees usually need removal.
• Spruce spider mites: fine stippling and bronzing can develop, especially during dry conditions. Confirm mites before treatment and use a locally approved control if damage is significant.
• Heat and drought stress: browning needles and thinning growth are common outside cool climates. Mulch, water deeply and avoid hot, exposed or paved sites.

Not known to be toxic to people, cats, dogs or horses. Needles are not food: swallowing them can irritate the mouth or stomach, and resin may irritate sensitive skin. Avoid animals drinking Christmas-tree water, particularly if additives have been used.

• Balsam fir (Abies balsamea)

  Very similar foliage, but its cone bracts are usually hidden within the cone; Fraser fir has conspicuous projecting bracts. Trees without cones can be difficult to distinguish.

• Douglas fir (Pseudotsuga menziesii)

  Douglas fir has pointed buds and hanging cones with distinctive three-pronged bracts; Fraser fir has rounded, resinous buds and upright cones.

The species name fraseri honours Scottish botanist and plant collector John Fraser.

Propagation. Grow from seed collected from mature cones before they disintegrate; seed normally benefits from cold, moist stratification before sowing. Named forms are usually grafted by specialist nurseries.
