Viburnum Plant Care

Viburnum (Viburnum opulus) belongs to the Viburnaceae family within the Viburnum genus. Viburnum is native to Europe, North America, Asia. Viburnum is also known as Guelder Rose, European Cranberrybush, Snowball Bush.

Viburnum displays an upright, spreading shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Viburnum produces clusters of small, fragrant white or pink flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Viburnum every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Viburnum thrives in full sun to part shade.

Viburnum opulus tolerates temperatures of 0–100°F. Viburnum prefers humidity levels of 40–70%.

Moist, well-draining loamy soil enriched with organic matter. Good drainage is essential for Viburnum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Viburnum every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to part shade and moist, well-draining loamy soil enriched with organic matter. Avoid low spots where water collects after rain.

Viburnum is suited to USDA Zone 3a – 8b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Viburnum can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Viburnum while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Viburnum is hardy down to USDA zone 3a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Viburnum can be propagated through softwood cuttings, semi-hardwood cuttings, seeds. Similar propagation techniques also apply to arrowwood viburnum plant care, which shares the same genus.

Viburnum is susceptible to aphids, scale insects, viburnum beetles. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
