Few trees compare with the fragrant splendor of a weeping cherry tree (Prunus pendula) in full blossom. These trees grow to an average height of 15 to 25 feet and reach a width around 20 feet. The graceful branches form drooping arches that often sweep the ground. This ornamental landscape tree thrives in moderate and cool climates in many areas of the United States. The small fruits on weeping cherry trees may entice visitors, in the form of wildlife and birds, to your landscape.
Grow your weeping cherry tree in well-draining soil. Although weeping cherries tolerate a variety of soils, these attractive trees thrive in soil compositions that allow water to easily flow around their roots. Increase the nutrients and porosity of your existing soil by incorporating organic compounds, such as compost, into the topsoil.
Cut away any overhanging limbs of larger, nearby trees that block sunlight from reaching your weeping cherry tree. This type of cherry tree needs bright sunlight to reach its full potential. Thin out interior branches of large, neighboring trees to allow more light to surround your weeping cherry.
Water your weeping cherry tree when the soil becomes slightly dry near its roots. Provide about 2 inches of water every week for young trees and seedlings. Mature flowering cherry trees seldom require regular watering, but providing a little supplemental moisture during droughts can help your tree flourish.
Examine your weeping cherry tree for evidence of pest infestations. These trees commonly suffer from borers, spider mites and tent caterpillars. Look for branches with galls, small lumps and dark bumps, which indicate the presence of fruit borers and diseases. Remove these branches with a pair of pruning shears, cutting 2 or 3 inches above the gall. Treat recurrent pest problems with a small amount of insecticide spray.
Fertilize your weeping cherry tree about once a month during its active growth period. Doing so will encourage a healthy weeping cherry tree to ward off many types of pests and diseases and will keep your tree looking its best. Purchase a fertilizer that lists weeping cherry trees on its label, and apply the fertilizer according to the enclosed instructions.
Trim up your tree to encourage healthy, new growth. Although these fruit trees don't require regular pruning, occasional trimming will enhance their health and appearance. Remove any broken or dead twigs and branches back to their originating branch. Cut out crowded branches that create an uneven appearance in the canopy.
