Rhadinothamnus rudis Plant Care

Rhadinothamnus rudis (Rhadinothamnus rudis) belongs to the Rutaceae family within the Rhadinothamnus genus. Rhadinothamnus rudis is native to Western Australia.

Rhadinothamnus rudis displays a compact, bushy shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 2.5 ft. Rhadinothamnus rudis produces small white fragrant flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Rhadinothamnus rudis every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Rhadinothamnus rudis thrives in bright indirect light. Avoid placing Rhadinothamnus rudis in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Rhadinothamnus rudis tolerates temperatures of 60–80°F. Rhadinothamnus rudis prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

Feed Rhadinothamnus rudis every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 bright indirect light and well-draining sandy soil with added organic matter for nutrients. Avoid low spots where water collects after rain.

Rhadinothamnus rudis is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Rhadinothamnus rudis can spread to about 3 ft (0.8 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Rhadinothamnus rudis 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 shrub in one year.

Rhadinothamnus rudis 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.

Rhadinothamnus rudis can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to rhadinothamnus anceps plant care, which shares the same genus.

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

Rhadinothamnus rudis grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Rhadinothamnus rudis is native to Western Australia. In cooler regions, grow Rhadinothamnus rudis as a houseplant or bring it indoors before the first frost.
