Columnar Mangrove Plant Care

Columnar Mangrove (Bruguiera cylindrica) belongs to the Rhizophoraceae family within the Bruguiera genus. Columnar Mangrove is native to tropical Asia and Australia. Columnar Mangrove is also known as Gray Mangrove, White Mangrove.

Columnar Mangrove displays a tall, mangrove tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Columnar Mangrove produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Columnar Mangrove 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.

Columnar Mangrove thrives in full sun.

Bruguiera cylindrica tolerates temperatures of 65–85°F. Columnar Mangrove prefers humidity levels of 60–90%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Sandy, loamy soil with good drainage. Good drainage is essential for Columnar Mangrove to prevent waterlogging, which leads to root rot and fungal issues.

Feed Columnar Mangrove 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 and sandy, loamy soil with good drainage. Avoid low spots where water collects after rain.

Columnar Mangrove is suited to USDA Zone 11a – 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.

Columnar Mangrove can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Columnar Mangrove 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.

Columnar Mangrove is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Columnar Mangrove can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to black mangrove plant care, which shares the same genus.

Columnar Mangrove is susceptible to mangrove scale, caterpillars. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Columnar Mangrove grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Columnar Mangrove is native to tropical Asia and Australia. In cooler regions, grow Columnar Mangrove as a houseplant or bring it indoors before the first frost.
