Oleo Plant Care

Oleo (Pseudopanax ferox) belongs to the Araliaceae family within the Pseudopanax genus. Oleo is native to New Zealand. Oleo is also known as Toothed Lancewood, Feather Duster.

Oleo displays a tall, upright tree growth habit, reaching up to 15 ft tall with a spread of approximately 8 ft. Oleo produces small, inconspicuous flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Oleo 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.

Oleo thrives in partial to full sun.

Pseudopanax ferox tolerates temperatures of 50–80°F. Oleo prefers humidity levels of 40–70%.

Well-draining, fertile soil with added organic matter. Good drainage is essential for Oleo to prevent waterlogging, which leads to root rot and fungal issues.

Feed Oleo 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 partial to full sun and well-draining, fertile soil with added organic matter. Avoid low spots where water collects after rain.

Oleo is suited to USDA Zone 12a.

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.

Oleo can spread to about 8 ft (2.4 m) and reach about 15 ft (5 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Oleo 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.

Oleo is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

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

Oleo 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.

Oleo grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Oleo is native to New Zealand. In cooler regions, grow Oleo as a houseplant or bring it indoors before the first frost.
