Saskatoon berries are juicy, berry-like fruits that grow on shrubs or small trees. They're also called serviceberries, prairie berries, juneberries, and shadbush, depending on where they grow.
The small, berry-like fruits ripen ... each time you lop off a piece of the tree. Isopropyl alcohol is good for disinfecting most garden tools. Saskatoon-juniper rust is another potential problem.
