Red Lauan Plant Care

Red Lauan (Parashorea densiflora) belongs to the Dipterocarpaceae family within the Parashorea genus. Red Lauan is native to Peninsular Malaysia. Red Lauan is also known as Lauan.

Red Lauan displays a tall canopy tree growth habit, reaching up to 100 ft tall with a spread of approximately 50 ft. Red Lauan produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Red Lauan 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.

Red Lauan thrives in full sun to partial shade.

Parashorea densiflora tolerates temperatures of 65–85°F. Red Lauan prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with high organic content. Good drainage is essential for Red Lauan to prevent waterlogging, which leads to root rot and fungal issues.

Feed Red Lauan every 8 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 well-draining loamy soil with high organic content. Avoid low spots where water collects after rain.

Red Lauan 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.

Red Lauan can spread to about 50 ft (15.2 m) and reach about 100 ft (30 m) tall. Space plants about 50 ft (15.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Red Lauan 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.

Red Lauan 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.

Red Lauan can be propagated through seeds, cuttings. Similar propagation techniques also apply to white seraya plant care, which shares the same genus.

Red Lauan is susceptible to bark beetles, termites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Red Lauan grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Red Lauan is native to Peninsular Malaysia. In cooler regions, grow Red Lauan as a houseplant or bring it indoors before the first frost.
