Chinese Stachyurus Plant Care

Chinese Stachyurus (Stachyurus chinensis) belongs to the Stachyuraceae family within the Stachyurus genus. Chinese Stachyurus is native to China and Taiwan. Chinese Stachyurus is also known as Evergreen Whorlflower.

Chinese Stachyurus displays an upright, spreading shrub growth habit, reaching up to 8 ft tall with a spread of approximately 10 ft. Chinese Stachyurus produces pendulous clusters of small, bell-shaped yellow flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Chinese Stachyurus every 7–10 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 Stachyurus thrives in partial shade to full sun.

Stachyurus chinensis tolerates temperatures of 45–75°F. Chinese Stachyurus prefers humidity levels of 40–70%.

Moist, well-draining soil with high organic content. Good drainage is essential for Chinese Stachyurus to prevent waterlogging, which leads to root rot and fungal issues.

Feed Chinese Stachyurus 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 partial shade to full sun and moist, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Chinese Stachyurus is suited to USDA Zone 11b.

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 Stachyurus can spread to about 10 ft (3 m) and reach about 8 ft (2 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Chinese Stachyurus 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 Stachyurus is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Chinese Stachyurus can be propagated through softwood cuttings, layering. Similar propagation techniques also apply to early stachyurus plant care, which shares the same genus.

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

Chinese Stachyurus grows outdoors in USDA Zone 11b. It survives winters down to planting zone 11b. Chinese Stachyurus is native to China and Taiwan. In cooler regions, grow Chinese Stachyurus as a houseplant or bring it indoors before the first frost.
