Cupaniopsis wadsworthii Plant Care

Cupaniopsis wadsworthii (Cupaniopsis wadsworthii) belongs to the Sapindaceae family within the Cupaniopsis genus. Cupaniopsis wadsworthii is native to Queensland.

Cupaniopsis wadsworthii displays a small to medium-sized tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Cupaniopsis wadsworthii produces small clusters of white or cream-colored flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Cupaniopsis wadsworthii 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.

Cupaniopsis wadsworthii thrives in full sun to partial shade.

Cupaniopsis wadsworthii tolerates temperatures of 60–85°F. Cupaniopsis wadsworthii prefers humidity levels of 40–70%.

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

Feed Cupaniopsis wadsworthii 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 well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Cupaniopsis wadsworthii is suited to USDA Zone 13a.

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.

Cupaniopsis wadsworthii can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Cupaniopsis wadsworthii 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.

Cupaniopsis wadsworthii is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Cupaniopsis wadsworthii can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to tuckeroo plant care, which shares the same genus.

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

Cupaniopsis wadsworthii grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Cupaniopsis wadsworthii is native to Queensland. In cooler regions, grow Cupaniopsis wadsworthii as a houseplant or bring it indoors before the first frost.
