Goniothalamus aurantiacus Plant Care

Goniothalamus aurantiacus (Goniothalamus aurantiacus) belongs to the Annonaceae family within the Goniothalamus genus. Goniothalamus aurantiacus is native to Thailand.

Goniothalamus aurantiacus displays an upright, bushy tree growth habit, reaching up to 10 ft tall with a spread of approximately 5 ft. Goniothalamus aurantiacus produces small, fragrant flowers in shades of white, yellow, or green.

Leaf size: approximately 6 inches.

Water a young or newly planted Goniothalamus aurantiacus 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.

Goniothalamus aurantiacus thrives in bright indirect light. Avoid placing Goniothalamus aurantiacus in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Goniothalamus aurantiacus tolerates temperatures of 65–80°F. Goniothalamus aurantiacus prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, acidic soil with high organic content. Good drainage is essential for Goniothalamus aurantiacus to prevent waterlogging, which leads to root rot and fungal issues.

Feed Goniothalamus aurantiacus 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 bright indirect light and well-draining, acidic soil with high organic content. Avoid low spots where water collects after rain.

Goniothalamus aurantiacus 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.

Goniothalamus aurantiacus can spread to about 5 ft (1.5 m) and reach about 10 ft (3 m) tall. Space plants about 5 ft (1.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Goniothalamus aurantiacus 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.

Goniothalamus aurantiacus 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.

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

Goniothalamus aurantiacus 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.

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