Chinese wingnut Plant Care

Chinese wingnut (Rhoiptelea chiliantha) belongs to the Juglandaceae family within the Rhoiptelea genus. Chinese wingnut is native to southwest China and north Vietnam and lives at the elevation of 700-1600m in mountainous areas. Chinese wingnut is also known as deciduous walnut.

Chinese wingnut displays a tall deciduous tree growth habit, reaching up to 60 ft tall with a spread of approximately 40 ft. Chinese wingnut produces inconspicuous greenish-yellow catkins.

Leaf size: approximately 12 inches.

Water a young or newly planted Chinese wingnut 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.

Chinese wingnut thrives in full sun to partial shade.

Rhoiptelea chiliantha tolerates temperatures of 50–100°F. Chinese wingnut prefers humidity levels of 30–70%.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Chinese wingnut to prevent waterlogging, which leads to root rot and fungal issues.

Feed Chinese wingnut 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.

Choose a spot with full sun to partial shade and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Chinese wingnut is suited to USDA Zone 9a – 10b.

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.

Chinese wingnut can spread to about 40 ft (12.2 m) and reach about 60 ft (18 m) tall. Space plants about 40 ft (12.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Chinese wingnut 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.

Chinese wingnut is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Chinese wingnut can be propagated through seeds, hardwood cuttings.

Chinese wingnut is susceptible to walnut caterpillar, walnut husk fly. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Chinese wingnut grows outdoors in USDA Zone 9a – 10b. It survives winters down to planting zone 9a. Chinese wingnut is native to southwest China and north Vietnam and lives at the elevation of 700-1600m in mountainous areas. In cooler regions, grow Chinese wingnut as a houseplant or bring it indoors before the first frost.
