Medicosma obovata Plant Care

Medicosma obovata (Medicosma obovata) belongs to the Rutaceae family within the Medicosma genus. Medicosma obovata is native to a restricted area of far north Queensland.

Medicosma obovata displays an upright, small tree or shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Medicosma obovata produces small white flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Medicosma obovata 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.

Medicosma obovata thrives in full sun to partial shade.

Medicosma obovata tolerates temperatures of 55–85°F. Medicosma obovata prefers humidity levels of 40–70%.

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

Feed Medicosma obovata 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 added organic matter for nutrients. Avoid low spots where water collects after rain.

Medicosma obovata is suited to USDA Zone 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.

Medicosma obovata 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 Medicosma obovata 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.

Medicosma obovata is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Medicosma obovata can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to medicosma elliptica plant care, which shares the same genus.

Medicosma obovata is susceptible to citrus whitefly, citrus leafminer, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Medicosma obovata grows outdoors in USDA Zone 12b. It survives winters down to planting zone 12b. Medicosma obovata is native to a restricted area of far north Queensland. In cooler regions, grow Medicosma obovata as a houseplant or bring it indoors before the first frost.
