Lunasia Plant Care

Lunasia (Lunasia amara) belongs to the Rutaceae family within the Lunasia genus. Lunasia is native to Malesia, New Guinea, and Queensland. Lunasia is also known as Kamuning, White Cheese Wood.

Lunasia displays a small tree, dense foliage growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Lunasia produces small fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Lunasia 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.

Lunasia thrives in partial shade to full sun.

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

Well-draining loamy soil with added sand and peat moss. Good drainage is essential for Lunasia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Lunasia 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 partial shade to full sun and well-draining loamy soil with added sand and peat moss. Avoid low spots where water collects after rain.

Lunasia 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.

Lunasia 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 Lunasia 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.

Lunasia 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.

Lunasia can be propagated through seeds, stem cuttings.

Lunasia 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.

Lunasia grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Lunasia is native to Malesia, New Guinea, and Queensland. In cooler regions, grow Lunasia as a houseplant or bring it indoors before the first frost.
