Evergreen Euonymus Plant Care

Evergreen Euonymus (Euonymus myrianthus) belongs to the Celastraceae family within the Euonymus genus. Evergreen Euonymus is native to central and southern China.

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

Leaf size: approximately 3 inches.

Water a young or newly planted Evergreen Euonymus 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.

Evergreen Euonymus thrives in full sun to part shade.

Euonymus myrianthus tolerates temperatures of 50–80°F. Evergreen Euonymus prefers humidity levels of 40–70%.

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

Feed Evergreen Euonymus 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

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.

Evergreen Euonymus is suited to USDA Zone 12a.

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.

Evergreen Euonymus 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 Evergreen Euonymus 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.

Evergreen Euonymus is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Evergreen Euonymus 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.

Evergreen Euonymus 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.

Evergreen Euonymus grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Evergreen Euonymus is native to central and southern China. In cooler regions, grow Evergreen Euonymus as a houseplant or bring it indoors before the first frost.
