Java Brucea Plant Care

Java Brucea (Brucea javanica) belongs to the Simaroubaceae family within the Brucea genus. Java Brucea is also known as Brucea.

Java Brucea displays a small to medium-sized tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Java Brucea produces small clusters of greenish-yellow flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Java Brucea 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.

Java Brucea thrives in full sun to partial shade.

Brucea javanica tolerates temperatures of 65–85°F. Java Brucea prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil mix with added organic matter for nutrients. Good drainage is essential for Java Brucea to prevent waterlogging, which leads to root rot and fungal issues.

Feed Java Brucea 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 mix with added organic matter for nutrients. Avoid low spots where water collects after rain.

Java Brucea 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.

Java Brucea can spread to about 15 ft (4.6 m) and reach about 20 ft (6 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 Java Brucea 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.

Java Brucea 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.

Java Brucea can be propagated through seeds, stem cuttings.

Java Brucea is susceptible to aphids, 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.

Java Brucea grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. In cooler regions, grow Java Brucea as a houseplant or bring it indoors before the first frost.
