How do you get a snowball tree to bloom?

To encourage a snowball tree (Viburnum opulus) to bloom, ensure it receives plenty of sunlight—ideally, it should be planted in a location with full sun to partial shade. Regular watering during dry spells helps maintain healthy growth, and applying a balanced fertilizer in early spring can promote flowering. Pruning should be done after flowering to shape the tree and remove any dead or weak branches, which can also enhance blooming in the following season.
