Three-anther Nutmeg Plant Care

Three-anther Nutmeg (Myristica trianthera) belongs to the Myristicaceae family within the Myristica genus. Three-anther Nutmeg is native to West Papua (Indonesia).

Three-anther Nutmeg displays a tall, evergreen tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Three-anther Nutmeg produces small, yellowish flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Three-anther Nutmeg 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.

Three-anther Nutmeg thrives in partial shade to full sun.

Myristica trianthera tolerates temperatures of 65–85°F. Three-anther Nutmeg prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with high organic content. Good drainage is essential for Three-anther Nutmeg to prevent waterlogging, which leads to root rot and fungal issues.

Feed Three-anther Nutmeg 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with partial shade to full sun and rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Three-anther Nutmeg 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.

Three-anther Nutmeg 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 Three-anther Nutmeg 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.

Three-anther Nutmeg 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.

Three-anther Nutmeg can be propagated through seeds. Similar propagation techniques also apply to wild nutmeg plant care, which shares the same genus.

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

Three-anther Nutmeg grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Three-anther Nutmeg is native to West Papua (Indonesia). In cooler regions, grow Three-anther Nutmeg as a houseplant or bring it indoors before the first frost.
