Broadleaf Spindle Plant Care

Broadleaf Spindle (Euonymus latifolius) belongs to the Celastraceae family within the Euonymus genus. Broadleaf Spindle is native to the Mediterranean region, south-central Europe, the Caucasus, and the Middle East as far as Iran, and it has been introduced to Ireland, Great Britain, and Belgium. Broadleaf Spindle is also known as Largeleaf Spindle.

Broadleaf Spindle displays an upright, dense shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Broadleaf Spindle produces small, inconspicuous greenish flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Broadleaf Spindle every 7–14 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.

Broadleaf Spindle thrives in full sun to part shade.

Euonymus latifolius tolerates temperatures of 50–80°F. Broadleaf Spindle prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Broadleaf Spindle to prevent waterlogging, which leads to root rot and fungal issues.

Feed Broadleaf Spindle 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 well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Broadleaf Spindle is suited to USDA Zone 6a – 9b.

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.

Broadleaf Spindle can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Broadleaf Spindle 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.

Broadleaf Spindle is hardy down to USDA zone 6a, 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.

Broadleaf Spindle can be propagated through softwood cuttings in spring, semi-hardwood cuttings in summer, seeds in fall. Similar propagation techniques also apply to wintercreeper plant care, which shares the same genus.

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

Broadleaf Spindle grows outdoors in USDA Zone 6a – 9b. It survives winters down to planting zone 6a. Broadleaf Spindle is native to the Mediterranean region, south-central Europe, the Caucasus, and the Middle East as far as Iran, and it has been introduced to Ireland, Great Britain, and Belgium.
