Planting Your Bare Root Mountain Ash

When to plant: November through March, whilst the tree is dormant and the ground isn't frozen

Planting tips:

• Soak roots in water for 2-4 hours before planting
• Dig a hole twice the width of the root system
• Plant at the same depth as the soil mark on the stem
• Space 6-8 metres apart for group planting
• Backfill with native soil mixed with well-rotted compost
• Water thoroughly after planting
• Apply a mulch around the base, keeping it clear of the trunk
• Stake for the first 2-3 years, especially in exposed positions
• Avoid planting in heavy, waterlogged clay

Care & Maintenance

• Water during dry spells in the first two growing seasons
• Feed with a general-purpose fertiliser in early spring (optional)
• Minimal pruning needed – remove dead, diseased, or crossing branches in winter
• Keep the base clear of weeds and grass for the first few years
• Generally low-maintenance once established
• Watch for fireblight in some areas (remove affected branches promptly)
• May be affected by aphids in spring (usually not serious)

Seasonal Interest

Late Spring (May): Masses of creamy-white flowers in large, flat-topped clusters (corymbs) create a frothy display and attract pollinators

Summer: Elegant, pinnate leaves (13-15 leaflets) create a delicate, ferny appearance; green berries begin to develop

Late Summer to Autumn (August-October): Spectacular display of bright orange-red berries in large, heavy clusters; foliage turns golden-yellow, orange, or red

Winter: Berries may persist (if birds haven't eaten them); attractive bare branch structure with silvery-grey bark

Wildlife Benefits

Mountain Ash is exceptional for supporting wildlife:

• Flowers provide nectar and pollen for bees and other pollinators in spring
• Berries are a vital autumn food source for thrushes, blackbirds, fieldfares, redwings, and waxwings
• Over 200 species of insects associated with rowan
• Host plant for various moth species
• Provides nesting sites in mature specimens
• Berries ripen early, providing food before many other trees
• In years of berry abundance, attracts rare winter migrants like waxwings

Ideal For

• Small to medium gardens
• Wildlife gardens
• Exposed, upland, and coastal sites
• Mixed native plantings
• Woodland edges and forest gardens
• Specimen tree planting
• Urban gardens (pollution-tolerant)
• Ornamental gardens with year-round interest
• Traditional cottage gardens
• Bird-friendly gardens
• Scottish and Celtic-themed gardens

Traditional Folklore & Cultural Significance

• Celtic tradition: Considered a magical tree offering protection against evil
• Highland connection: The Scottish symbol; grows naturally in the Highlands
• Rowan crosses: Twigs traditionally made into crosses for protection
• May Day celebrations: Associated with spring festivals
• Mountain guardian: Often found growing wild in remote, mountainous areas
• Place names: Many Scottish and Northern English locations named after rowan

Edible Uses

Rowan berries (harvest September-October):

• Can be made into jelly (traditional accompaniment to game)
• Rowan wine and liqueurs
• Must be cooked and are very tart – not for eating raw
• High in vitamin C
• Best harvested after the first frost to reduce bitterness
• Note: While edible when cooked, rowan berries are best left for the birds given their exceptional wildlife value

Things to Consider

• Berries can create some ground litter (though birds usually eat them quickly)
• May be susceptible to fireblight in some areas (a bacterial disease)
• Relatively short-lived compared to oaks or beeches (typically 80-100 years)
• Berries are very attractive to birds – they may strip the tree within days
• Prefers not to be in very heavy, waterlogged clay
• Can sucker occasionally from the roots

Design Ideas

• Specimen planting: Perfect as a focal point in small gardens
• Wildlife corner: Combine with other berry-bearing natives like hawthorn and holly
• Autumn display: Plant with other trees for autumn colour (birch, cherry, maple)
• Underplanting: Complement with spring bulbs and shade-tolerant perennials
• Group planting: Plant in threes or fives for dramatic berry display
• Coastal gardens: Excellent for exposed seaside locations

Companion Plants

Create beautiful combinations with:

• Spring bulbs (daffodils, bluebells) beneath
• Ferns and hostas for shade beneath the canopy
• Heathers for Scottish Highland themes
• Birch trees for complementary bark and foliage
• Holly for evergreen contrast and additional berries
• Foxgloves and primroses for woodland edge effect

Berry Production

• Trees begin producing berries from 3-5 years old
• Mature trees can produce thousands of berries

• Heavy berry crops occur in "mast years" (typically every 2-3 years)
• Exceptional berry years attract rare winter visitors like waxwings from Scandinavia

Why Choose Bare Root?

Bare root trees are lifted from the field during dormancy and supplied without soil around the roots. This traditional method offers several advantages:

• More economical than container-grown trees
• Better root development and establishment
• Lower carbon footprint (no plastic pots or compost)
• Available during the optimal planting season
• Establishes quickly and reliably

Location Guidelines

Suitable for gardens with:

• Minimum garden size: 100 square metres (for single tree)
• Plant at least 6 metres from buildings
• Works well in lawns, borders, or as specimen tree
• Suitable for front gardens and urban settings

Bring the beauty of the Scottish Highlands to your garden with Mountain Ash – a graceful native tree that offers spring blossom, spectacular autumn berries, and vital food for birds, all in a manageable size perfect for British gardens.

Please see our bare root plant guides for more information. We've put together a collect of help and advice articles covering what bare root plants are, why they are a good choice, which plants are available bare root, when and where to plant.

Deciduous plants supplied bare root during the dormancy period will not have any leaves at this time; top growth will just be brown and twiggy to start with and will come into leaf in the spring. This is perfectly normal. The plants we supply are healthy will an extensive root system. Please see the final picture for an illustration of how your plants will look when they are delivered.
