Narrow-leaved Pittosporum Plant Care

Narrow-leaved Pittosporum (Pittosporum angustifolium) belongs to the Pittosporaceae family within the Pittosporum genus. Narrow-leaved Pittosporum is native to mostly inland, continental Australia. Narrow-leaved Pittosporum is also known as Willow Pittosporum.

Narrow-leaved Pittosporum displays an upright, dense shrub growth habit, reaching up to 8 ft tall with a spread of approximately 6 ft. Narrow-leaved Pittosporum produces small, fragrant, creamy white blooms in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Narrow-leaved Pittosporum 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.

Narrow-leaved Pittosporum thrives in full sun to partial shade.

Pittosporum angustifolium tolerates temperatures of 50–80°F. Narrow-leaved Pittosporum prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Narrow-leaved Pittosporum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Narrow-leaved Pittosporum 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 full sun to partial shade and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Narrow-leaved Pittosporum 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.

Narrow-leaved Pittosporum can spread to about 6 ft (1.8 m) and reach about 8 ft (2 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 Narrow-leaved Pittosporum 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.

Narrow-leaved Pittosporum 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.

Narrow-leaved Pittosporum can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to pittosporum cornifolium plant care, which shares the same genus.

Narrow-leaved Pittosporum 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.

Narrow-leaved Pittosporum grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Narrow-leaved Pittosporum is native to mostly inland, continental Australia. In cooler regions, grow Narrow-leaved Pittosporum as a houseplant or bring it indoors before the first frost.
