Saskatoon
Amelanchier alnifolia
In other languages: Saskatoonbes (Nederlands) · Amélanchier à feuilles d’aulne (Français)
The saskatoon is a serviceberry from western and northern North America, from the Canadian prairies to Alaska. It is an upright, multi-stemmed shrub that is covered in small, white, starry flowers in April–May, often before the leaves have fully opened. In June–July come large, sweet, dark blue berries with a faint almond note from the seeds. In autumn the rounded leaves turn yellow to orange-red. It is extremely hardy, and cultivars such as ‘Thiessen’ and ‘Smoky’ have been selected for large, tasty fruit.
Caution: Over the years it produces suckers and can become a wider thicket. Remove unwanted suckers every year if you want to keep the shrub compact.

Identify
Saskatoon: how do you recognise it?
- Habit
- Upright, multi-stemmed shrub 2–4 m tall and 2–3 m wide, slowly widening through suckers.
- Leaves
- Round to oval, 2–5 cm, toothed mainly towards the tip, like those of alder; yellow to orange-red in autumn.
- Flower
- White, starry flowers in short, upright clusters, in April–May.
- Fruit
- Round berries 1–1.5 cm across, red at first, then dark purple-blue with a bloom, sweet and juicy, in June–July.
- Roots
- Wide-spreading; produces suckers around the shrub.
Flowering: April–May · Harvest and fruit: June–July · Plants: March–April and October–December · Pruning: February–March
In your garden
Why grow it?
- Fresh fruit in June–July, earlier than most berries: delicious fresh, in jam, in pies or frozen.
- Three seasons of interest: white blossom in spring, blue berries in summer and autumn colour.
- The flowers are an early food source for bees; the berries attract birds.
- Very hardy and easy: grows in almost any soil, chalk included.
- Self-fertile: a single shrub will crop.
Saskatoon: where does it grow best?
- Sun or partial shade; you get the most and sweetest fruit in sun.
- Almost any soil: sand, loam or clay, slightly acid to chalky.
- Normally moist, well-drained soil; it does not tolerate standing water.
- Plant 2–2.5 m apart; in a fruiting hedge, 1–1.5 m.

Goes well with
- Blackcurrant: Another easy fruit bush for a sunny fruiting hedge.
- Hazel: Together an edible hedge, with nuts in autumn.
- Guelder rose: White flowers and red berries for birds, in the same soil.
- Crocus: Early flowers under the shrub before the leaves appear.
Maintenance
Saskatoon: when and how to plant it?
Plant in March–April and October–December.
- Plant in March–April or October–December; bare-root shrubs only while dormant.
- Dig a hole twice as wide as the root ball and mix in compost.
- Set the shrub at the same depth as it was in its pot or the nursery and firm the soil well.
- Water generously straight away, even if it is raining.
- Spread a mulch of compost or wood chips around the base.
Care
- Watering
- Weekly in dry spells in the first year. After that only in long droughts, especially while the fruit swells in May–June.
- Feeding
- In March, a little compost or organic fruit fertiliser. Too much nitrogen gives long shoots and less fruit.
- Mulching
- A layer of compost or wood chips in spring keeps the soil moist and weed-free.
- Netting
- In June, net the shrub as soon as the berries colour, or blackbirds will eat them.
- Harvesting
- Pick the berries when they are fully dark purple-blue. They do not all ripen at once, so pick several times. They freeze well.
Tip: In June, as soon as the berries start to turn red, throw a net over the shrub: blackbirds know exactly when they are ripe.
Saskatoon: when to prune it?
Pruning months: February–March.
When: Prune in February–March, while the shrub is dormant and before the buds break.
How:
- Cut out dead, diseased, crossing and inward-growing branches.
- The best fruit grows on stems a few years old: each year, remove one or two of the oldest, thickest stems at the base.
- Keep 8–12 healthy stems of different ages.
- Remove surplus suckers around the edge of the shrub.
Caution: Do not shorten every branch: it flowers on last year’s wood, and if you cut off all the tips you cut off the crop.
Propagation
- Suckers
- In late autumn or late winter: dig up a sucker with a piece of root and replant it straight away in its new spot.
- Seed
- Sow seeds from ripe berries in autumn in a pot left outdoors; they germinate after the winter cold. Seedlings do not always resemble the parent.
Saskatoon: how does it get through the winter?
Hardy to −40 °C.
- Extremely hardy, to about −40 °C: it never needs protection in Belgium.
- In a large pot: choose a container at least 50 cm across and stand it against a wall in winter.
- Feel free to leave fallen leaves as a mulch under the shrub.
Diseases and pests
- Blackbirds and other birds: They sometimes eat every ripe berry. Netting the shrub from the moment the fruit colours helps.
- Fire blight: Flowers, leaves and shoots turn brown-black as if scorched, and the tips bend over. Cut well back into healthy wood and disinfect your secateurs.
- Aphids: On young shoots in spring. Ladybirds usually deal with them; otherwise hose them off.
- Little fruit: Too much shade, or all the tips cut back. Plant in a sunnier spot and only remove old stems at the base.
Through the year
- February: Pruning: remove old stems at the base.
- March: Pruning. Planting. Add compost.
- April: Flowering. Bees.
- May: Flowering. Water in dry weather.
- June: Net the shrub as the berries colour. First pickings.
- July: Harvest. Freeze the berries or make jam.
- August: Water in long dry spells.
- October: Autumn colour. Planting.
- November: Planting. Remove suckers.
- December: Plant bare-root shrubs.
Use
Edible and useful
- Berries (June–July)
- The berries ripen in June–July, turning from red to dark purple-black. Pick them quickly, as blackbirds and starlings love them too; a net helps. They taste sweet, a little of cherry and almond, and are lovely fresh, in muffins or pancakes, as jam or dried like currants.
- Storing
- A few days in the fridge; they can be frozen spread out on a tray. Dried, they keep for months in a closed jar.
Caution: Like many plants in the rose family, the small seeds contain small amounts of substances that can release cyanide. Normal portions of fresh or cooked fruit are no problem, but do not grind the seeds. Only eat berries from a tree you have identified with certainty.
Eating and using is at your own risk: see the terms of use.

You and this species
Did you know?
- The Canadian city of Saskatoon is named after this berry; the word comes from the Cree language.
- Indigenous peoples of North America mixed dried saskatoon berries with dried meat and fat to make pemmican, a food that kept for a long time.
- Botanically the ‘berries’ are tiny apples: like apples and pears, the saskatoon belongs to the rose family.
