Hupeh wingnut Plant Care

Hupeh wingnut (Pterocarya hupehensis) belongs to the Juglandaceae family within the Pterocarya genus. Hupeh wingnut is native to China.

Hupeh wingnut displays a tall, spreading tree growth habit, reaching up to 60 ft tall with a spread of approximately 40 ft. Hupeh wingnut produces inconspicuous greenish flowers in long catkins.

Leaf size: approximately 10 inches.

Water a young or newly planted Hupeh 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.

Hupeh wingnut thrives in full sun to partial shade.

Pterocarya hupehensis tolerates temperatures of 0–90°F. Hupeh wingnut prefers humidity levels of 40–70%.

Rich, moist, well-draining soil with high organic content. Good drainage is essential for Hupeh wingnut to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hupeh wingnut 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 partial shade and rich, moist, well-draining soil with high organic content. Avoid low spots where water collects after rain.

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.

Hupeh 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 Hupeh 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.

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.

Hupeh wingnut can be propagated through seeds, root cuttings. Similar propagation techniques also apply to caucasian wingnut plant care, which shares the same genus.

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