How can you prune your summer-flowering shrubs in order to increase fragrant flowering?
Here we see a Philadelphus ( Mock Orange ) in full flower. In order to keep getting good annual flowering from your deciduous summer-flowering shrubs, it pays to prune them directly after flowering.
Be bold and fairly brutal by cutting the flowered stems down to the ground, or to a dominant joint where new growth emerges from a side shoot. This is the stem we keep and remove the old flowered stem.
