Colubrina pedunculata Plant Care

Colubrina pedunculata (Colubrina pedunculata) belongs to the Rhamnaceae family within the Colubrina genus. Colubrina pedunculata is native to Christmas Island, an Australian territory in the north-eastern Indian Ocean.

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

Leaf size: approximately 3 inches.

Water a young or newly planted Colubrina pedunculata 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.

Colubrina pedunculata thrives in full sun to partial shade.

Colubrina pedunculata tolerates temperatures of 60–85°F. Colubrina pedunculata prefers humidity levels of 40–70%.

Well-draining sandy soil mix with organic matter. Good drainage is essential for Colubrina pedunculata to prevent waterlogging, which leads to root rot and fungal issues.

Feed Colubrina pedunculata 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 soil mix with organic matter. Avoid low spots where water collects after rain.

Colubrina pedunculata is suited to USDA Zone 11a – 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.

Colubrina pedunculata 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 Colubrina pedunculata 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.

Colubrina pedunculata is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Colubrina pedunculata can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to asian colubrina plant care, which shares the same genus.

Colubrina pedunculata 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.

Colubrina pedunculata grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Colubrina pedunculata is native to Christmas Island, an Australian territory in the north-eastern Indian Ocean. In cooler regions, grow Colubrina pedunculata as a houseplant or bring it indoors before the first frost.
