Arrowwood Viburnum Plant Care

Arrowwood Viburnum (Viburnum dentatum) belongs to the Viburnaceae family within the Viburnum genus. Arrowwood Viburnum is native to the eastern United States and Canada from Maine south to northern Florida and eastern Texas. Arrowwood Viburnum is also known as Arrowwood, Toothed Viburnum, Southern Arrowwood.

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

Leaf size: approximately 4 inches.

Water a young or newly planted Arrowwood 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.

Arrowwood Viburnum thrives in full sun to part shade.

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

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

Feed Arrowwood 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.

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.

Arrowwood 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 Arrowwood 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.

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.

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

Arrowwood 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.
