Bonin Island Pandanus Plant Care

Bonin Island Pandanus (Pandanus boninensis) belongs to the Pandanaceae family within the Pandanus genus. Bonin Island Pandanus is native to and common in the Distylium-Schima dry forests and Raphiolepis-Livistona dry forests of the Bonin Islands, Japan.

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

Leaf size: approximately 24 inches.

Water a young or newly planted Bonin Island Pandanus 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.

Bonin Island Pandanus thrives in full sun to partial shade.

Pandanus boninensis tolerates temperatures of 65–85°F. Bonin Island Pandanus 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 Bonin Island Pandanus to prevent waterlogging, which leads to root rot and fungal issues.

Feed Bonin Island Pandanus 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 loamy, well-draining soil with added sand and peat moss. Avoid low spots where water collects after rain.

Bonin Island Pandanus is suited to USDA Zone 13b.

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.

Bonin Island Pandanus 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 Bonin Island Pandanus 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.

Bonin Island Pandanus 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.

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

Bonin Island Pandanus 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.

Bonin Island Pandanus grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Bonin Island Pandanus is native to and common in the Distylium-Schima dry forests and Raphiolepis-Livistona dry forests of the Bonin Islands, Japan. In cooler regions, grow Bonin Island Pandanus as a houseplant or bring it indoors before the first frost.
