How to prune guelder rose

Immediately after flowering (early to midsummer). Use a renewal approach: cut one to three of the oldest stems back to near ground level each year after bloom, stimulating vigorous new shoots. Reduce overall height by cutting remaining stems back to a strong lateral. Avoid shearing — it spoils the plant's natural open form.

Annually after flowering for ongoing renewal; harder renovation every 5-7 years if needed. Guelder rose (Viburnum opulus) benefits from pruning to control size and encourage flowering on younger wood. Prune immediately after flowering — it blooms on wood produced the previous year, so late pruning removes next year's buds. Remove one-third of the oldest stems at the base each year to keep the plant productive and open. Also remove dead, damaged or crossing branches.
