The weeping cherry tree (Prunus subhirtella) grows approximately 30 to 40 feet tall with a 25-foot spread. The weeping branches of the tree often drape all the way to the ground in long, graceful arches. Each spring flowers appear in shades of pink that quickly fade to white. Green foliage production follows the flowers. In the fall the tree sports a brilliant yellow color until the leaves fall to the ground. Grown as a landscape specimen the tree has no value in fruit production.
Plant in a location that offers full sunlight. Well-draining soil is ideal. Choose a location that offers shelter from high winds so the tree does not sustain damage while establishing itself.
Place the bud union of the weeping cherry 2 to 3 inches above the soil surface when planting. Placing the bud union below the soil surface can often cause it to suffer rot, which can be life-threatening to the tree.
Apply 2 to 3 inches of mulch--such as peat moss, leaf debris or bark chips--around the tree. Do not allow the mulch to touch the tree's bud union. Mulch will help the soil retain moisture and prevent weed growth. The weeping cherry does not tolerate turf grasses around its base, as the grass robs the tree of essential nutrients. Remove all grass from under the tree.
Pull any sucker growth that grows under the weeping cherry tree. Suckers will often grow up to 9 feet from the base of the tree. The tree's suckers do not grow true to the parents form and must be pulled up promptly.
Water the weeping cherry tree weekly. The tree enjoys moist soil conditions, but will not tolerate standing water or overly wet soil.
Spray aphids and spider-mite infestations off using a garden hose before they become established. Aphids appear as tiny red, brown, black or green insects clustered along the plants new growth. Spider mites appear as tiny red dots on the foliage or stems with fine webbing. Apply horticultural oil if the tree shows signs of a scale infestation. Scale insects appear as tiny brown dots on the stems of the tree.
Prune away the woven nests of the tent caterpillar and discard. Tent caterpillars create large spiderweb-like nests on the trees branches. Prune any areas of the tree that suffer from gall. Gall appears as black swellings on the branches of the tree. Prune the entire branch off the tree and discard. The weeping cherry does not require yearly pruning--except to remove dead or damaged wood.
