Spiraea shrubs respond well to hard pruning and it is essential for keeping a healthy plant. Spring flowering varieties need the old and weak stems removed after flowers have faded and the summer flowering varieties shoule be pruned back in early spring to a few inches above the ground.
Varieties include: Low-growing bumald spirea (S. bumalda) and medium-sized Japanese spirea (S. japonica), Vanhoutte spirea (S. vanhouttei), the classic bridal wreath spirea, which needs plenty of room if grown as single speicmen.
