Chengiopanax sciadophylloides Plant Care

Chengiopanax sciadophylloides (Chengiopanax sciadophylloides) belongs to the Araliaceae family within the Chengiopanax genus. Chengiopanax sciadophylloides is native to Japan.

Chengiopanax sciadophylloides displays a tall, upright shrub growth habit, reaching up to 6 ft tall with a spread of approximately 3 ft. Chengiopanax sciadophylloides produces small white flowers in umbels.

Leaf size: approximately 8 inches.

Water a young or newly planted Chengiopanax sciadophylloides 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.

Chengiopanax sciadophylloides thrives in bright indirect light. Avoid placing Chengiopanax sciadophylloides in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Chengiopanax sciadophylloides tolerates temperatures of 65–80°F. Chengiopanax sciadophylloides prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with added organic matter like compost or peat moss. Good drainage is essential for Chengiopanax sciadophylloides to prevent waterlogging, which leads to root rot and fungal issues.

Feed Chengiopanax sciadophylloides 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 bright indirect light and rich, well-draining soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Chengiopanax sciadophylloides is suited to USDA Zone 13b.

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.

Chengiopanax sciadophylloides can spread to about 3 ft (0.9 m) and reach about 6 ft (2 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Chengiopanax sciadophylloides 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.

Chengiopanax sciadophylloides 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.

Chengiopanax sciadophylloides can be propagated through seeds, stem cuttings.

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