False Mangrove Plant Care

False Mangrove (Conocarpus lancifolius) belongs to the Combretaceae family within the Conocarpus genus. False Mangrove is native to coastal and riverine areas of Somalia, Djibouti, and Yemen. False Mangrove is also known as Somali Buttonwood.

False Mangrove displays an upright, spreading tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. False Mangrove produces small inconspicuous flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted False 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.

False Mangrove thrives in full sun.

Conocarpus lancifolius tolerates temperatures of 60–90°F. False Mangrove prefers humidity levels of 40–70%.

Well-draining sandy soil mix with good organic content. Good drainage is essential for False Mangrove to prevent waterlogging, which leads to root rot and fungal issues.

Feed False 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.

Choose a spot with full sun and well-draining sandy soil mix with good organic content. Avoid low spots where water collects after rain.

False Mangrove is suited to USDA Zone 13a.

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.

False Mangrove can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune False 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.

False Mangrove 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.

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

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

False Mangrove grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. False Mangrove is native to coastal and riverine areas of Somalia, Djibouti, and Yemen. In cooler regions, grow False Mangrove as a houseplant or bring it indoors before the first frost.
