The breeding of dwarf sour cherries began in the 1940's by Dr. Les Kerr. The past 50 years of breeding have combined cold hardiness, dwarf stature and good fruit quality into the final product. The cherry releases by the University of Saskatchewan are a great tasting cherry with high sugar content. They also have very good potential for mechanical harvesting which is necessary for commercial fruit production.
The sour cherry was created by crossing the Mongolian cherry with the sweet cherry. This happened quite frequently in nature. The sour cherry was then crossed to another Mongolian cherry, a new and improved variety to get the dwarf sour cherry.

Trees range from 1.75 meters to 2.5 meters (5-8 feet) tall. Some suckering can happen with some varieties. This amount of suckering increases if the soil around the tree is continually tilled or disturbed. These trees are unique as they are not grafted and are on their own roots. Sour cherries usually flower in mid to late May. These trees can be quite stunning in the spring as the flowers open slightly before the leaves emerge and the tree turns into a ball of white flowers.
The leaves are very glossy and shiny which adds some ornamental value. The fruit is usually ripe in early August and can range in color from red to dark red to a black red. Cherry splitting is caused by dry followed by wet conditions during the ripening process
Plant in a hole that is big enough to accommodate the entire root mass of the tree. They should be planted about 2.5-5 cm (1-2 inches) deeper than they were in the nursery container.
They should be planted about 1.5-2 m (5-7 feet) apart from each other or other plants.
Water immediately after planting and water well until established.
Most cherry bushes are not self fertile and need a different variety to set fruit.
Prune in early spring before the bushes break dormancy. Diseased or damaged wood can be removed at any time. Thinning cuts are better suited to cherries than heading back cut. A heading back cut (taking the top/tip portion off of a branch) tends to remove vegetative buds and the plant will have nothing to make new shoots from. Thinning cuts (when you remove an entire branch here and there) is better suited as you will not be removing a specific kind of bud.
Never remove more than 25% of wood in one season. Cherries can be selectively regenerated by removing some of the old branches every year and allowing the new branches to slowly take over
Cherries can be handpicked or shaken off. Just beware if you shake the cherries off you are liable to get lots of stems in with the fruit.
They should be picked in the cool parts of the morning or evening and refrigerated as soon after picking.
