Roundleaf Snowberry Plant Care

Roundleaf Snowberry (Symphoricarpos rotundifolius) belongs to the Caprifoliaceae family within the Symphoricarpos genus. Roundleaf Snowberry is also known as Roundleaf Coralberry.

Roundleaf Snowberry displays an upright, spreading shrub growth habit, reaching up to 4 ft tall with a spread of approximately 5 ft. Roundleaf Snowberry produces small, bell-shaped pink or white flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Roundleaf Snowberry every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Roundleaf Snowberry thrives in full sun to part shade.

Symphoricarpos rotundifolius tolerates temperatures of 0–100°F. Roundleaf Snowberry prefers humidity levels of 40–70%.

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

Feed Roundleaf Snowberry every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 soil with organic matter. Avoid low spots where water collects after rain.

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

Roundleaf Snowberry can spread to about 5 ft (1.5 m) and reach about 4 ft (1 m) tall. Space plants about 5 ft (1.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Roundleaf Snowberry 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 shrub 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 shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Roundleaf Snowberry can be propagated through softwood cuttings, seeds.

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