Weeping cherry trees can bring beauty and grace to any landscaped environment. Along with that elegance can come some problems. Good maintenance can prevent most problems from becoming serious conditions. Choosing the proper location can alleviate some other problems.
Aphids, borers, tent caterpillars and scales are common insects affecting weeping cherry trees. Japanese beetles can do considerable damage. Some cause damage that is merely cosmetic while others cause health issues.
Powdery mildew, black knot, leaf spot and twig cankers are among the more common disease to watch for in weeping cherry trees. Gray mold, Verticillium wilt and wood rot are other diseases that can affect weeping cherries. Loss of leaves can be severe if diseases become serious, which can further stress the tree.
Dry conditions can stress a weeping cherry tree, which paves the way for pests and diseases to attack. Conversely, soil that is too wet can drown roots. The fruits, though inedible for humans, attract many birds. Depending on the location of the tree, the bird droppings can be problematic.
