Pruning Spring-Flowering Shrubs
Early spring and pruning is so intertwined in the public’s mind that chopping spring-flowering shrubs happens every spring.
Many non-gardeners (as well as the occasional gardener) succumb to the call of saw, secateurs and loppers, happily depriving themselves of spring blooms every year.
The most common shrubs that should not be pruned in late winter or early spring include:
Deutzia
Forsythia
Hydrangeas: mophead (H. macrophylla), lacecap (H. macrophylla normalis) & oakleaf (H. quercifolia)
Lilac (Syringa spp.)
Nanking cherry (Prunus tomentosa)
Bridal wreath spirea
Viburnum
Weigela

what happes if you do prune then? I was thinking of cutting specific branches of my forsythia to propagate.
If you prune spring-flowering Forsythia before it blooms, you won’t get any blooms in that season. You can easily propagate Forsythia by rooting greenwood cuttings in late spring or early summer, or semi-ripe cuttings in late summer. Use rooting hormone (IBA) that promotes rooting in shrubs (there’s different strengths for annuals, shrubs and trees).
