Once established, the Scottish Laburnum requires little maintenance beyond regular watering and occasional pruning. The tree can be pruned in the late winter or early spring to remove any damaged or dead branches and to maintain a desired shape. Pruning can also help to encourage more prolific flowering in the following season.
Overall, the Scottish Laburnum is a versatile and striking tree with many uses and benefits.
