Answer: I've never heard of a Yoshima cherry, but Yoshino cherries (Prunus yedoensis) are one of the celebrated trees of the Washington, D.C. cherry blossom festival. It has very fragrant, showy flowers in spring. Some varieties are upright and spreading (to 25 ft.), others are "weeping." They need a mostly sunny growing site, protected from high winds. Soil should be moderately moist and well-drained, with a slightly acidic pH (5.0-7.0). Apply mulch around the tree and keep soil evenly moist through this first growing season. Prune only damaged, crossing or diseased branches after the tree finishes blooming in spring. Cherries are succeptible to many pests and diseases, though they are seldom a serious problem, especially if there is plenty of air circulation around the tree.
