Black Palm Plant Care

Black Palm (Benstonea atrocarpa) belongs to the Pandanaceae family within the Benstonea genus. Black Palm is native to the swamp and peat forests of Thailand, Peninsular Malaysia, Singapore and Sumatra. Black Palm is also known as Benstonea.

Black Palm displays a tall, clumping palm growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Black Palm produces small, inconspicuous flowers in clusters.

Leaf size: approximately 18 inches.

Water a young or newly planted Black Palm 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.

Black Palm thrives in bright indirect light. Avoid placing Black Palm in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Benstonea atrocarpa tolerates temperatures of 65–85°F. Black Palm prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich loamy soil with added organic matter. Good drainage is essential for Black Palm to prevent waterlogging, which leads to root rot and fungal issues.

Feed Black Palm 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 bright indirect light and well-draining, rich loamy soil with added organic matter. Avoid low spots where water collects after rain.

Black Palm 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.

Black Palm can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Black Palm 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.

Black Palm 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.

Black Palm can be propagated through division, air layering, seeds. Similar propagation techniques also apply to dwarf benstonea plant care, which shares the same genus.

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

Black Palm grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Black Palm is native to the swamp and peat forests of Thailand, Peninsular Malaysia, Singapore and Sumatra. In cooler regions, grow Black Palm as a houseplant or bring it indoors before the first frost.
