African milkbush Plant Care

African milkbush (Polyceratocarpus gossweileri) belongs to the Annonaceae family within the Polyceratocarpus genus. African milkbush is native to Africa.

African milkbush displays a tall tree, spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. African milkbush produces small, greenish-yellow flowers with a pleasant fragrance.

Leaf size: approximately 6 inches.

Water a young or newly planted African milkbush 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 milkbush thrives in partial shade to full sun.

Polyceratocarpus gossweileri tolerates temperatures of 65–85°F. African milkbush prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining loamy soil with added organic matter for nutrients. Good drainage is essential for African milkbush to prevent waterlogging, which leads to root rot and fungal issues.

Feed African milkbush 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 loamy soil with added organic matter for nutrients. Avoid low spots where water collects after rain.

African milkbush 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 milkbush 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 African milkbush 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 milkbush 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 milkbush can be propagated through seeds, air layering. Similar propagation techniques also apply to polyceratocarpus scheffleri plant care, which shares the same genus.

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

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