Viburnums are fabulous shrubs to attract wildlife into your garden. Wentworth is one of the best of the deciduous Viburnum. It has masses of flat flower heads in May, which turn into the brightest red berries you have ever seen. Beneficial pollinators will cover this shrub while in bloom. Birds and other small animals love to feast on the berries from late summer all of the way into the winter. The fall foliage is a vivid mix of red hues. So many good things from just one shrub.
Viburnum are great for adding to a naturalized area or including in a Cottage Garden plan. The vertical growth and dense foliage makes for a nice informal hedge. Wentworth Viburnum has both male and female flowers on one plant, making it self fertile. No need to have multiple shrubs planted together, although yields of the berries may be higher when planted with a companion.
Wentworth Viburnum Care
Wentworth prefers moist, well drained soils. It is not choosy about light conditions. Full sun to part shade will help this shrub bloom profusely. Mulching in the fall will help to improve soils to retain more moisture over time. Wentworth Viburnum is very tolerant of pollution and does wonderfully in urban gardens.
Pruning should only be done after the blooming has ended. Removing all of the blooms will also remove potential berries. Ideally a light pruning of dead, dying, diseased and diagonal branches is done early in the spring to remove any winter damage. Any sucker stems that grow up are easily removed to keep the shrub inside its allotted area.Fertilizing can also be done in the early spring. A well blanched, slow release food applied as a top dressing will feed the shrub through the growing season.
Wentworth Viburnum Spacing
Wentworth Viburnum reaches a mature height of 8- 10 feet and a width of 8-10 feet. Planting is recommended at 8 foot on center.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
