Forest Acacia Plant Care

Forest Acacia (Albizia zygia) belongs to the Fabaceae family within the Albizia genus. Forest Acacia is native to West and Central Africa. Forest Acacia is also known as East African Albizia.

Forest Acacia displays a fast-growing tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Forest Acacia produces showy clusters of fragrant pink or white flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Forest Acacia 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.

Forest Acacia thrives in full sun to partial shade.

Albizia zygia tolerates temperatures of 60–85°F. Forest Acacia prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Forest Acacia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Forest Acacia 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 full sun to partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Forest Acacia is suited to USDA Zone 10b – 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.

Forest Acacia 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 Forest Acacia 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.

Forest Acacia is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Forest Acacia can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to acle plant care, which shares the same genus.

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

Forest Acacia grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Forest Acacia is native to West and Central Africa. In cooler regions, grow Forest Acacia as a houseplant or bring it indoors before the first frost.
