Oak-leaf Chorilaena Plant Care

Oak-leaf Chorilaena (Chorilaena quercifolia) belongs to the Rutaceae family within the Chorilaena genus. Oak-leaf Chorilaena is native to the karri forests of south-west Western Australia.

Oak-leaf Chorilaena displays a small tree or shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Oak-leaf Chorilaena produces small white or pink fragrant flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Oak-leaf Chorilaena 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.

Oak-leaf Chorilaena thrives in full sun to partial shade.

Chorilaena quercifolia tolerates temperatures of 60–85°F. Oak-leaf Chorilaena prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Oak-leaf Chorilaena to prevent waterlogging, which leads to root rot and fungal issues.

Feed Oak-leaf Chorilaena 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 sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Oak-leaf Chorilaena is suited to USDA Zone 13a.

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.

Oak-leaf Chorilaena can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Oak-leaf Chorilaena 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.

Oak-leaf Chorilaena 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.

Oak-leaf Chorilaena can be propagated through seeds, semi-hardwood cuttings.

Oak-leaf Chorilaena is susceptible to scale insects, aphids, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Oak-leaf Chorilaena grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Oak-leaf Chorilaena is native to the karri forests of south-west Western Australia. In cooler regions, grow Oak-leaf Chorilaena as a houseplant or bring it indoors before the first frost.
