Likewise, people ask, can viburnum be cut back hard?

Late winter or early spring, depending on local weather conditions, is the time to start hard pruning. The first year, cut back one-third of the large, old branches to just about a few inches from the ground. After the hard pruning is complete, maintain the viburnum with regular simple pruning just after it flowers.

To shape a viburnum, prune it lightly immediately after flowering. Remove the flower heads and cut back any branches that spoil the shape of the shrub to a pair of newly-sprouted leaves. Remember that removing the flower heads will preclude the formation of fruit, which can be very attractive in many viburnums.

How do you prune a viburnum Burkwoodii?

Cut up to one-third of the oldest, crowded stems on the Burkwood viburnum back to just above ground level or the base of the shrub, if desired. This type of pruning helps to improve air circulation inside the shrub's canopy, which is most beneficial when a shrub has been plagued by fungal diseases in the past.
