It is best to plant the Saskatoon in spring. If growing multiple plants, separate them at about one meter (3 feet) apart to optimize air flow quality and reduce the likelihood of disease.
They are cold-hardy and adapt well to various soil environments, but do prefer a well-drained soil.
When the Pacific Serviceberry plant is young, prune weak and diseased branches and stems with a pair of sharp pruning shears.
If planning to grow the Saskatoon for fruit production, be mindful that healthy stems produce prime fruit once the plant has aged two to four years old.
