Pittosporum longisepalum Plant Care

Pittosporum longisepalum (Pittosporum longisepalum) belongs to the Pittosporaceae family within the Pittosporum genus.

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

Leaf size: approximately 4 inches.

Water a young or newly planted Pittosporum longisepalum 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.

Pittosporum longisepalum thrives in full sun to partial shade.

Pittosporum longisepalum tolerates temperatures of 50–80°F. Pittosporum longisepalum prefers humidity levels of 40–70%.

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

Feed Pittosporum longisepalum 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.

Pittosporum longisepalum 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.

Pittosporum longisepalum 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 Pittosporum longisepalum 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.

Pittosporum longisepalum 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.

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

Pittosporum longisepalum 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.

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