Early Richmond CherryPrunus cerasus 'Early Richmond'
A strong, upright, compact sour cherry tree. Spring white flowers are borne on long pedicels in clusters of 2–4. Sour cherries are less prone to frost, because they are the latest blooming of the stone fruits. The leathery leaves are dark green on top, pale green beneath. It is self fertile and bears without a pollinator in late June. Fruiting begins earlier for sour cherry trees and their productive life is shorter than sweet. A standard cherry tree will produce fruit in 3–5 years. Sour cherries are hardier in cold climates, resistant to drought, and more tolerant of humid rainy conditions than sweet. Prune in late winter or early spring. They are pruned more than sweet cherry trees to stimulate new shoot production. Selective limb thinning may be necessary to maintain adequate light and spur development inside the trees.
