(Spiraea prunifolia)

Bridal wreath spirea, also known as Bridalwreath spirea

A favored ornamental shrub, known for cascades of white spring blooms, bridal wreath spirea thrives with proper pruning. Post-bloom, cut back a quarter of old stems to ground level to rejuvenate. Thin crowded areas for light and air flow, enhancing plant vigor and bloom potential. Optimal pruning occurs in late spring or early summer, immediately after flowering, to ensure flower bud development for the following year. Regular pruning maintains shape and health, preventing overgrowth and promoting robust flowering.

What Are the Benefits of Pruning Bridal Wreath Spirea?

Pruning bridal wreath spirea encourages more prolific blooming and healthier, more vigorous growth by removing dead or diseased wood. It also helps in preventing pest infestations and fungal diseases by increasing air circulation within the canopy.

What Is the Best Time for Pruning Bridal Wreath Spirea?

Spring

Summer

Pruning during this period is optimal because it allows gardeners to shape the plant without sacrificing next year's flowers. Bridal wreath spirea blooms on old wood, meaning that the flower buds form on growth from the previous season. Pruning after the blooming season allows the plant to heal and produce new growth that will set buds for the following year. This timing also ensures that any potential damage from winter is removed, encouraging healthy new growth. It is also a good time to thin out any crowded branches, which improves air circulation and reduces the risk of disease. Moreover, trimming in late spring or early summer gives the plant sufficient time to recover before entering dormancy in the winter.
