The right way to prune your flowering shrubs to ensure the best display the following year.
Pruning spring-flowering shrubs
Read the transcript
Prune deciduous spring-flowering shrubs such as forsythia, flowering currant and spring-flowering spiraea just after they finish blooming. That leaves time for the new growth that will carry next year’s flowers.
Remove dead, diseased, damaged and weak shoots back to their point of origin. If the shrub is crowded, take out up to around a quarter of the oldest stems at ground level.
Cut back the flowered growth to strong young shoots lower down. Feed if needed to support new growth.
