How to grow Saskatoon serviceberry

Amelanchier alnifolia · serviceberry, saskatoon, saskatoon berry

Saskatoon serviceberry (Amelanchier alnifolia) — saskatoon serviceberry (Amelanchier alnifolia) is a very hardy deciduous shrub or small tree, 1–8 m tall, that survives −60 °C. Clusters of white flowers open in spring, often before the leaves, and the sweet, dark purple berries with a hint of almond ripen in early summer, in mid to late July in Saskatchewan. A relative of the apple, it is eaten fresh, frozen, dried or in jams and pies, and has bright yellow to orange autumn leaves. Saskatoon is the serviceberry bred for fruit, with named varieties. It is self-fertile, though bees carrying pollen between plants raise the yield.

Growing notes

Light

Full sun for the best crop; in part sun it gives fewer, poorer berries. It flowers early, so keep it out of frost pockets and low-lying spots.

Soil

Tolerates most soils but does best in well-drained loam or sandy loam, pH 6–7 (5–8 is tolerated). Clay is fine if it drains and stays evenly moist; avoid waterlogging.

Care

For a hedge plant 1–1.5 m apart, 2.5–5 cm deeper than in the pot, so it forms a multi-stemmed bush. Keep the soil moist for the first 2–3 weeks, then give about 2.5 cm of water a week unless it rains; plants established for 2–3 years need little watering. The roots are shallow, so keep grass and weeds 1 m away and lay a thick woody mulch, but not over the base of the stems. Use no mineral fertiliser at planting; each spring spread compost or rotted manure. Prune in autumn or winter, taking out a few stems at the base to let in light, and keep suckers in check; cut an old, unproductive bush down to 15 cm to renew it. Plant at least 2 km from wild junipers, which carry saskatoon-juniper rust, and protect the bark from deer and rabbits. The leaves contain cyanide and can be fatal to animals that eat a lot of them.

How to tell it is ripe

The berries turn from white to red and finally deep purple.
Ripening is uneven, so a bush needs several pickings.
Fully ripe berries are soft and at their sweetest.
Slightly underripe berries are firmer and hold more pectin and vitamin C but less sugar.
Lift the branches to find berries hidden under the leaves and pull whole bunches gently into your hand, or shake them onto a tarp; pick in the cool of morning or evening, chill the berries at once, and pick promptly, as birds can strip a bush before the fruit is fully ripe.
