Trimming of Allegheny Viburnum


Alleghany viburnum (Viburnum rhytidophylloides Alleghany), sometimes spelled Allegheny, is a semi-evergreen shrub with a moderate growth rate and multi-stemmed, upright form. Growing 8 to 10 feet tall and wide, Alleghany viburnum has dark green, leather-like foliage that is wrinkled. Growing up to 6 inches long, the leaves of Alleghany viburnum turn a dark green to brown in fall. Emerging in spring, the white flat-topped, 4-inch wide flowers appear to light up the bush with color and texture. Versatile, Alleghany viburnum grows in a wide range of soil varieties, including dry and compacted soils. Drought- and heat-tolerant, Alleghany viburnum prefers moist, soil and full sun, and is hardy in zones 4 to 8.

Step 1

Prune spring-flowering Alleghany viburnum after flowering, when most of the blooms have shed. Use sharp pruning shears to ensure a smooth and precise cut.

Step 2

Cut back the Alleghany viburnum with cuts up to 1/2 inches in diameter. Remove all weak, gnarled and crossing branches by removing the entire branch from its point of origin.

Step 3

Trim all disease- or pest-infected branches by cutting of the whole branch, ensuring the Alleghany shrub is not infected in its entirety.

Step 4

Pinch off dead or spent blooms by cutting off the bloom. Removing the old and withered bloom helps send needed nutrients to other areas of the shrub.

Step 5

Remove all suckers, or shoots arising from the base of the Alleghany shrub, as soon as they are visible.

Step 6

Open up mature Alleghany viburnum shrubs by trimming the center growth and cutting back all terminal branches to the outwardly facing bud.
