Calophyllum heterophyllum Plant Care

Calophyllum heterophyllum (Calophyllum heterophyllum) belongs to the Calophyllaceae family within the Calophyllum genus. Calophyllum heterophyllum is native to West Papua (Indonesia) and Papua New Guinea.

Calophyllum heterophyllum displays a tall, spreading tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Calophyllum heterophyllum produces small, fragrant white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Calophyllum heterophyllum 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.

Calophyllum heterophyllum thrives in full sun to partial shade.

Calophyllum heterophyllum tolerates temperatures of 65–85°F. Calophyllum heterophyllum prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich loamy soil with added organic matter for moisture retention. Good drainage is essential for Calophyllum heterophyllum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Calophyllum heterophyllum 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, rich loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Calophyllum heterophyllum 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.

Calophyllum heterophyllum 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 Calophyllum heterophyllum 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.

Calophyllum heterophyllum 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.

Calophyllum heterophyllum can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to santa maria plant care, which shares the same genus.

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

Calophyllum heterophyllum grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Calophyllum heterophyllum is native to West Papua (Indonesia) and Papua New Guinea. In cooler regions, grow Calophyllum heterophyllum as a houseplant or bring it indoors before the first frost.
