Pinnately Divided Aralidium Plant Care

Pinnately Divided Aralidium (Aralidium pinnatifidum) belongs to the Torricelliaceae family within the Aralidium genus.

Pinnately Divided Aralidium displays a tall, slender tree growth habit, reaching up to 15 ft tall with a spread of approximately 6 ft. Pinnately Divided Aralidium produces small clusters of white, fragrant flowers.

Leaf size: approximately 8 inches.

Water a young or newly planted Pinnately Divided Aralidium 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.

Pinnately Divided Aralidium thrives in filtered sunlight to partial shade. Avoid placing Pinnately Divided Aralidium in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Aralidium pinnatifidum tolerates temperatures of 60–80°F. Pinnately Divided Aralidium prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

Feed Pinnately Divided Aralidium 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 filtered sunlight to partial shade and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Pinnately Divided Aralidium 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.

Pinnately Divided Aralidium can spread to about 6 ft (1.8 m) and reach about 15 ft (5 m) tall. Space plants about 6 ft (1.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Pinnately Divided Aralidium 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.

Pinnately Divided Aralidium 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.

Pinnately Divided Aralidium can be propagated through seeds, division of offsets.
