Murraya caloxylon Plant Care

Murraya caloxylon (Murraya caloxylon) belongs to the Rutaceae family within the Murraya genus. Murraya caloxylon is native to Malaysia, Thailand, and Sumatra in Indonesia.

Murraya caloxylon displays a compact, evergreen shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Murraya caloxylon produces fragrant white flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Murraya caloxylon every 7–10 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.

Murraya caloxylon thrives in full sun to partial shade.

Murraya caloxylon tolerates temperatures of 60–85°F. Murraya caloxylon prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Murraya caloxylon to prevent waterlogging, which leads to root rot and fungal issues.

Feed Murraya caloxylon 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 loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Murraya caloxylon 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.

Murraya caloxylon 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 Murraya caloxylon 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.

Murraya caloxylon 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.

Murraya caloxylon can be propagated through softwood cuttings, air layering, seeds. Similar propagation techniques also apply to orange jasmine plant care, which shares the same genus.

Murraya caloxylon 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.

Murraya caloxylon grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Murraya caloxylon is native to Malaysia, Thailand, and Sumatra in Indonesia. In cooler regions, grow Murraya caloxylon as a houseplant or bring it indoors before the first frost.
