Pruning of fringe trees is mainly carried out in early spring. Mainly cut off senescent branches, diseased branches, cross branches, drooping branches and inner branches. Flowering branches generally do not need to be cut short, because they are terminal flower buds. If cut short, it will not bloom. However, if the tree shape is not beautiful, you can also shorten the flowering branches or branches to encourage them to grow more side branches to correct the tree shape.
