Celtis jessoensis Plant Care

Celtis jessoensis (Celtis jessoensis) belongs to the Cannabaceae family within the Celtis genus. Celtis jessoensis is native to Japan and Korea.

Celtis jessoensis displays a medium to large deciduous tree growth habit, reaching up to 50 ft tall with a spread of approximately 30 ft. Celtis jessoensis produces inconspicuous small greenish flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Celtis jessoensis 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.

Celtis jessoensis thrives in full sun to partial shade.

Celtis jessoensis tolerates temperatures of 50–90°F. Celtis jessoensis prefers humidity levels of 40–70%.

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

Feed Celtis jessoensis every 8 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 partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Celtis jessoensis 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.

Celtis jessoensis can spread to about 30 ft (9.1 m) and reach about 50 ft (15 m) tall. Space plants about 30 ft (9.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Celtis jessoensis 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.

Celtis jessoensis 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.

Celtis jessoensis can be propagated through seeds, hardwood cuttings. Similar propagation techniques also apply to african sugarberry plant care, which shares the same genus.

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

Celtis jessoensis grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Celtis jessoensis is native to Japan and Korea. In cooler regions, grow Celtis jessoensis as a houseplant or bring it indoors before the first frost.
