Bignay Plant Care

Bignay (Antidesma bunius) belongs to the Phyllanthaceae family within the Antidesma genus. Bignay is native to South Asia, Southeast Asia, Melanesia, and northern Australia. Bignay is also known as Antidesma, Wild Cherry, Currant Tree.

Bignay displays a small tree or shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Bignay produces small inconspicuous flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Bignay 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.

Bignay thrives in full sun to partial shade.

Antidesma bunius tolerates temperatures of 60–85°F. Bignay prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

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

Bignay is suited to USDA Zone 10a – 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.

Bignay can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Bignay 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.

Bignay 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.

Bignay can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to ghaesembilla plant care, which shares the same genus.

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

Bignay grows outdoors in USDA Zone 10a – 12b. It survives winters down to planting zone 10a. Bignay is native to South Asia, Southeast Asia, Melanesia, and northern Australia. In cooler regions, grow Bignay as a houseplant or bring it indoors before the first frost.
