Which late-flowering shrubs should be pruned in spring?

摘要

Pruning fast-growing, late-blooming shrubs in early spring keeps their size in check and produces a perfectly balanced display of flowers.Shrubs that flower in late summer, such as Spirea japonica, produce flowers on stems that grow earlier in the year during spring and summer. They are almost always vigorous shrubs with abundant blooms appearing at the end of upright or gracefully arching stems, such as Buddteja dauidii.
