Saskatoon berry

Sun

Full sun to partial shade; full sun gives the best flowering and fruit crops.

Water

Water regularly while establishing and during dry spells as fruit develops. Established plants tolerate some drought, but crops suffer in dry soil.

Soil

Well-drained loam is ideal; tolerates clay, sandy soil and mildly acidic to alkaline conditions. Avoid waterlogged ground.

Height

6-15 ft (1.8-4.6 m), occasionally taller

Spread

5-12 ft (1.5-3.7 m), widening further through suckers if unmanaged

Flowers

Clusters of white flowers in early to mid-spring, usually as the leaves emerge.

Foliage

Rounded to oval green leaves with coarse teeth mainly on the upper half; yellow, orange or red autumn colour.

Growth rate

Moderate

• Water deeply through the first two growing seasons, allowing the surface soil to dry slightly between waterings.
• Keep soil evenly moist during flowering and fruit swelling, without leaving roots waterlogged.
• Apply 2-3 in (5-8 cm) of organic mulch, keeping it clear of the stems.
• Top-dress with compost in spring; avoid heavy nitrogen feeding, which encourages leafy growth rather than fruit.
• Remove unwanted suckers at ground level to keep the clump within its space.
• If protecting fruit from birds, use wildlife-safe, taut netting on a frame and check it daily.

Pruning. In late winter, remove dead, damaged and crossing stems, then thin a few of the oldest stems at ground level on established bushes. Retain healthy younger wood and avoid shearing, which removes flowering and fruiting shoots.

Pick berries in early to midsummer when they are fully blue-purple, slightly soft and sweet; fruit within a cluster may ripen unevenly. Lift ripe berries gently from their stalks and refrigerate promptly, or freeze them for later use. Nursery-grown plants usually give their first worthwhile crop about 3-5 years after planting, depending on plant size and growing conditions.

Late winter

Thin established bushes and remove dead or damaged stems before growth begins.

Early spring

Plant while dormant where soil is workable; add compost and renew mulch.

Spring

Watch flowers and new shoots for frost damage or fire blight; maintain moisture during dry weather.

Early summer

Fit wildlife-safe fruit protection before berries colour, if needed.

Early to midsummer

Harvest fully ripe berries in several passes.

Autumn

Plant in mild regions, remove unwanted suckers and clear diseased fallen leaves.

• Use as an informal edible hedge, allowing enough width for its branching and suckering habit.
• Place at a sunny woodland edge with shade-tolerant groundcovers beneath it.
• Combine with native grasses and flowering perennials in a loose, wildlife-friendly border within its native range.
• Grow near a patio or path where spring blossom and autumn colour can be seen, but keep ripe fruit away from paving that must stay clean.

Garden styles it suits: Edible landscape, Food forest, Native hedgerow, Woodland, Wildlife garden and Cottage garden.

Plant it with: Chokeberry, Red-twig dogwood, Wild strawberry, Yarrow, Purple coneflower and Little bluestem.

Wildlife: Spring flowers provide pollen and nectar for insects, including native bees. Birds and small mammals eat the fruit, and dense stems provide shelter.

• Birds take ripening berries: protect selected bushes with taut, wildlife-safe netting on a frame, or leave part of the crop for wildlife.
• Serviceberry rust causes orange spots or distorted fruit: remove affected material, clear fallen leaves and choose locally resistant selections where available; nearby junipers can host part of the disease cycle.
• Fire blight causes blackened, hooked shoot tips: prune affected shoots well below visible damage in dry weather, disinfect tools between cuts and avoid excessive nitrogen.
• Powdery mildew coats leaves with white growth: improve airflow by thinning crowded stems, avoid drought stress and choose a sunnier position for new plants.

Ripe berries are edible for people. Leaves, young shoots and seeds contain cyanogenic compounds; wilted foliage is a particular concern for grazing animals, including horses, and substantial ingestion can cause serious poisoning. Do not let cats or dogs chew foliage or eat large quantities of fruit, and do not deliberately crush or eat the seeds.

• Canadian serviceberry (Amelanchier canadensis)

  Usually has more elongated leaves with fine teeth extending farther down the margins; Saskatoon leaves are generally rounder with coarse teeth concentrated toward the tip.

• Allegheny serviceberry (Amelanchier laevis)

  Often forms a taller, more tree-like plant and has smooth, bronze-purple emerging leaves; Saskatoon usually has rounder leaves and a more shrubby, suckering habit.

• Chokecherry (Prunus virginiana)

  Has long, narrow flower and fruit clusters, finely toothed pointed leaves and fruit containing one hard stone. Saskatoon has shorter clusters and berries with several small seeds and a persistent star-shaped calyx.

Saskatoon comes from a Cree name for the fruit, while alnifolia means 'alder-leaved', referring to the leaf shape.

Propagation. Separate rooted suckers while dormant to preserve the parent plant's characteristics. Seed needs cold stratification, may have complex dormancy and will not reliably reproduce named fruit cultivars; softwood cuttings are possible but can be difficult to root.

Accepted botanical name

Amelanchier alnifolia
