The weeping white cherry tree is stunning with its showy white blossoms. The tree can grow up to 20 to 30 feet tall and 15 to 20 feet wide. The tree's main top branches tend to hang down toward the ground as they grow, creating a "weeping" effect. Although the weeping cherry tree is adaptable to most soil types, it does require quite a bit of upkeep to maintain its attractive, weeping shape.
Prune your weeping cherry tree regularly in the fall or late summer. Prune for the first time when the tree is still young. Unlike other fruit tree varieties that you would normally prune in winter, weeping cherry trees need pruning closer to their growing season to prevent silver leaf disease.
Trim your weeping cherry tree to retain its "weeping" shape. Using pruning shears, remove the suckers and water spouts to keep the nutrients flowing to the strong leader branches that are drooping toward the ground. Pruning away other growth on the tree will help to strengthen the leaders so they can hold the weight of the weeping branches. These branches should grow from the top of the tree.
Cut the new growth back on the leader branches to about one-eighth of an inch above the bud. Make the cut on an angle. If you want the leader branches to droop all the way to the ground, don't prune them.
Remove any dead, damaged or diseased wood from the tree. Also remove any fallen leaves, branches and old fruit on the ground around the tree. This will help to prevent disease.
Apply a pruning paste to cover your pruning cuts to protect the tree from disease. Try using an asphalt-based tree paste.
