What is a Saskatoon bush? Also known as western juneberry, prairie berry or western serviceberry, Saskatoon bush (Amelanchier alnifolia) is native to the area extending from the inland Northwest and the Canadian prairies to the southern Yukon. Saskatoon shrubs are attractive plants that bloom in spring and produce scads of bluish-purple Saskatoon berries in summer.
Saskatoon berries, with a flavor reminiscent of cherry with a hint of almond, are rich in protein, fiber and antioxidants. Saskatoon bushes generally reach heights of 6 to 10 feet (2-3 m.), depending on the cultivar. Similarly, fall color may vary from red to bright yellow.
Growing Saskatoon Bushes
A type of serviceberry, Saskatoon shrubs are especially valued for their cold-hardiness, as this tough plant can survive numbing temperatures of -60 F. (-51 C.).
Nearly any type of well-drained soil is suitable for Saskatoon bushes, although the shrubs don’t do well in heavy clay.
Saskatoon Bush Care
Begin with disease- and pest-free stock from a reputable nursery, as Saskatoon bushes are vulnerable to pests and disease.
Most Saskatoon bushes are self-fruiting, which means it isn’t necessary to plant another bush nearby. However, a second bush can sometimes generate larger harvests.
Amend the soil by digging in organic matter such as compost, grass clippings or chopped leaves. Don’t fertilize Saskatoon shrubs at planting time.
Water as needed to keep the soil moist but never soggy. It’s best to water at the base of the shrub and avoid sprinklers, as damp foliage makes the shrub more susceptible to fungal diseases.
Keep weeds in check; Saskatoon shrubs don’t compete well. Mulch the shrub to control weeds and keep the soil evenly moist. However, don’t mulch until late spring when the soil is warm and relatively dry.
Prune Saskatoon shrubs to remove dead and damaged growth. Pruning also improves air circulation throughout the foliage.
Check Saskatoon bushes for pests frequently, as Saskatoon shrubs are vulnerable to aphids, mites, leafrollers, sawflies and others. Many pests can be controlled by regular use of insecticidal soap spray.
