Fragrant screw pine Plant Care

Fragrant screw pine (Pandanus odorifer) belongs to the Pandanaceae family within the Pandanus genus. Fragrant screw pine is native to Polynesia, Australia, South Asia, and the Philippines. Fragrant screw pine is also known as Kewra.

Fragrant screw pine displays a tall, palm-like tree growth habit, reaching up to 20 ft tall with a spread of approximately 10 ft. Fragrant screw pine produces fragrant white flowers on long spikes.

Leaf size: approximately 24 inches.

Water a young or newly planted Fragrant screw pine 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.

Fragrant screw pine thrives in full sun to partial shade.

Pandanus odorifer tolerates temperatures of 65–85°F. Fragrant screw pine prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Loamy, well-draining soil with added sand and peat moss. Good drainage is essential for Fragrant screw pine to prevent waterlogging, which leads to root rot and fungal issues.

Feed Fragrant screw pine 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 full sun to partial shade and loamy, well-draining soil with added sand and peat moss. Avoid low spots where water collects after rain.

Fragrant screw pine is suited to USDA Zone 10b – 12b.

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.

Fragrant screw pine can spread to about 10 ft (3 m) and reach about 20 ft (6 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Fragrant screw pine 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.

Fragrant screw pine is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Fragrant screw pine can be propagated through air layering, stem cuttings. Similar propagation techniques also apply to barkley pandanus plant care, which shares the same genus.

Fragrant screw pine is susceptible to spider mites, mealybugs. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Fragrant screw pine grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Fragrant screw pine is native to Polynesia, Australia, South Asia, and the Philippines. In cooler regions, grow Fragrant screw pine as a houseplant or bring it indoors before the first frost.
