Pruning spiraea x vanhouttei — FAQ
When should I prune spiraea x vanhouttei?
Immediately after flowering finishes, typically late spring to early summer. Remove up to one-quarter of the oldest, woodiest stems at ground level. Shorten the remaining flowered stems by up to one-third, cutting back to a strong side shoot or bud. This opens the centre and stimulates the vigorous arching new growth that will carry next season's flowers.
How often does spiraea x vanhouttei need pruning?
Annually. Yes, Vanhoutte spirea needs pruning immediately after flowering — it blooms in spring on the previous year's wood, so pruning in spring or winter removes the flower buds. Cut out the oldest, thickest stems at the base and shorten flowered shoots by one-third to encourage new arching growth for next year.
