Korean evodia Plant Care

Korean evodia (Tetradium daniellii) belongs to the Rutaceae family within the Tetradium genus. Korean evodia is native to Korea and southwestern China. Korean evodia is also known as Korean bee bee tree, Evodia, Tetradium.

Korean evodia displays a small to medium-sized tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Korean evodia produces clusters of small white flowers in late spring to early summer.

Leaf size: approximately 6 inches.

Water a young or newly planted Korean evodia 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.

Korean evodia thrives in full sun to partial shade.

Tetradium daniellii tolerates temperatures of 50–85°F. Korean evodia prefers humidity levels of 40–70%.

Well-draining loamy soil mix with added perlite for improved drainage. Good drainage is essential for Korean evodia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Korean evodia 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 partial shade and well-draining loamy soil mix with added perlite for improved drainage. Avoid low spots where water collects after rain.

Korean evodia is suited to USDA Zone 4a – 8b.

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.

Korean evodia can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Korean evodia 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.

Korean evodia is hardy down to USDA zone 4a, 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.

Korean evodia can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to chinese evodia plant care, which shares the same genus.

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

Korean evodia grows outdoors in USDA Zone 4a – 8b. It survives winters down to planting zone 4a. Korean evodia is native to Korea and southwestern China.
