African Nutmeg Plant Care

African Nutmeg (Pycnanthus angolensis) belongs to the Myristicaceae family within the Pycnanthus genus. African Nutmeg is native to tropical Africa. African Nutmeg is also known as Ilomba, Akom.

African Nutmeg displays a tall, upright tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. African Nutmeg produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted African 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.

African Nutmeg thrives in partial shade to full sun.

Pycnanthus angolensis tolerates temperatures of 65–80°F. African 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 African Nutmeg to prevent waterlogging, which leads to root rot and fungal issues.

Feed African 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.

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.

African Nutmeg 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.

African 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 African 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.

African Nutmeg 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.

African Nutmeg can be propagated through seeds, stem cuttings.

African Nutmeg is susceptible to 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.

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