David's viburnum, also known as David's viburnum

Native to China, david's viburnum is valued for its evergreen foliage, metallic blue berries, and leathery leaves. To maintain shape and encourage vigorous growth, prune david's viburnum just after flowering in late spring to early summer.

What Are the Benefits of Pruning David's Viburnum?

Pruning david's viburnum encourages rejuvenation, leading to more vibrant blooms. Selective cutting back helps in maintaining plant health by removing any diseased or pest-infested branches, which can prevent the spread of pathogens.

What Is the Best Time for Pruning David's Viburnum?

Spring

Summer

Pruning david's viburnum during late spring or early summer is advised due to the completion of its bloom cycle. Pruning at this time allows gardeners to shape the plant and remove any spent flowers, which encourages healthier growth and prepares david's viburnum for the next flowering season. Moreover, trimming in this period also helps avoid cutting off newly developing flower buds, which form following the bloom period. This timing aligns with david's viburnum's active growth phase when it can heal from pruning cuts more efficiently, reducing the risk of stress or disease. Seasonal considerations include avoiding pruning in late fall or winter to prevent damage from frost to freshly cut stems, as david's viburnum enters a period of dormancy during colder months.
