About Viburnum Shrubs

For a flowering shrub with abundant benefits—fragrance, fruit, colorful foliage, pollinator appeal, and more—look no further than viburnums. The species offers more than 150 evergreen, semi-evergreen, and deciduous woody plants from which to choose. Also known as cranberrybush, hobblebush, arrowwood, nannyberry, or snowball bush, viburnum range in size from 2 to 20 feet tall and usually serve in the landscape as screening, hedge, or focal points.

Depending on the variety, viburnum provides year-round visual interest: The cream/white or pale pink bloom clusters can be lace-cap, dome, and snowball-shaped, with intoxicating or light perfume (although some have no scent). In fall, the flowers, favored by bees and butterflies, give way to yellow, orange, red, pink, blue, or black fruits attractive to birds and wildlife, and foliage on plants that are not evergreen change to glossy red or violet, or purple. 

All this and viburnums are easy to care for: fast-growing, not fussy about soil, needing little to no pruning, and seldom troubled by diseases or pests. 

Planting

Viburnums thrive in full sun to partial or mostly shade, depending on the variety.  

Provide moisture-retaining but well-draining, fertile soil. Add compost or aged manure, if necessary, before planting. The soil pH requirements vary by species; pH 5.5 to 6.5 is average. Check the variety, test the soil, and amend it as required. 

When to Plant Viburnum

• Fall planting is preferred, but early spring planting is also possible as long as the shrubs are kept well-watered throughout the spring and summer. If planting in the summer, water well during hot and dry periods.

How to Plant Viburnum

• Dig a hole as deep as the root ball and 2 times as wide. Set plants so that top roots are at the soil level or slightly below.
• Half-fill the hole with soil, and then water it well to settle the soil. Fill in with remaining soil.
• On the soil surface, form a rim of soil around the outer edge of the hole.
• Water inside the ring.
• Space plants 4 to 10 feet apart, depending on the variety’s estimated size at maturity.

With their colorful leaves and red berries, viburnum offer plenty of fall and winter interest, too.

Growing

• Water with a soaking once weekly if rainfall is less than 1 inch.
• Once established, mulch with 4 to 6 inches of pine straw or 2 to 3 inches of bark.
• Fertilizer is seldom applied. In spring, apply a few shovelfuls of compost or aged manure. In autumn, feed the roots by mixing whole fish meal with some compost.
• In early spring prune selectively to maintain height and spread.
• If an overgrown shrub requires a hard pruning (shearing), do it in early spring or after the bloom period.
