Campylospermum serratum Plant Care

Campylospermum serratum (Campylospermum serratum) belongs to the Ochnaceae family within the Campylospermum genus. Campylospermum serratum is native to Tropical Asia, from Sulawesi, Indonesia to Hainan, Zhōngguó/China and over to southwestern India.

Campylospermum serratum displays a small tree, shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Campylospermum serratum produces small, inconspicuous flowers.

Leaf size: approximately 5 inches.

Water a young or newly planted Campylospermum serratum 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.

Campylospermum serratum thrives in full sun to partial shade.

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

Well-draining sandy loam with organic matter. Good drainage is essential for Campylospermum serratum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Campylospermum serratum 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 sandy loam with organic matter. Avoid low spots where water collects after rain.

Campylospermum serratum 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.

Campylospermum serratum 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 Campylospermum serratum 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.

Campylospermum serratum 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.

Campylospermum serratum can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to campylospermum amplectens plant care, which shares the same genus.

Campylospermum serratum 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.

Campylospermum serratum grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Campylospermum serratum is native to Tropical Asia, from Sulawesi, Indonesia to Hainan, Zhōngguó/China and over to southwestern India. In cooler regions, grow Campylospermum serratum as a houseplant or bring it indoors before the first frost.
