How to Prune an Autumn Jazz Viburnum


There are more than 100 species of viburnum, including autumn jazz viburnum, or viburnum dentatum. They grow up to 10 feet tall and 12 feet wide, with white clusters of flowers that bloom between May and June. The ideal conditions include full sun to partial shade and medium, well-drained soil. This variety's flowers don't have a scent and make way for blue-black berries that wildlife and birds like to eat. Prune autumn jazz viburnum to maintain a good shape and keep the plant healthy.

Step 1

Use hand-held pruning shears when cutting off smaller, young branches or shoots because they are thin enough to be cut cleanly. Use a pruning saw for larger and more brittle branches.

Step 2

Remove damaged, weak or dead branches in the early spring. They are blocking air circulation and sunlight from reaching other branches.

Step 3

Pinch off the ends of stems to promote bushier growth. Grasp the stems in between your thumb and index finger, just above a node where the leaves and buds attach to the branch. Pull off the ends.

Step 4

Thin out the autumn jazz viburnum by cutting down larger branches that are inside the bush's bulk. Look for those that are crossing, rubbing each other or growing vertically up alongside the center branch.

Step 5

Prune branches by cutting them at their collar, the thicker section where they meet other branches. This is where the tissue is most likely to re-grow, avoiding infections caused by the open wound.

Tips and Warnings

  • Don't remove more than one-fourth of the autumn spice viburnum each season. Don't leave stumps when you prune. Avoid tearing the wood bark when making cuts.
