Rinorea welwitschii Plant Care

Rinorea welwitschii (Rinorea welwitschii) belongs to the Violaceae family within the Rinorea genus. Rinorea welwitschii is native to Africa.

Rinorea welwitschii displays a small tree or shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Rinorea welwitschii produces small, inconspicuous flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Rinorea welwitschii 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.

Rinorea welwitschii thrives in filtered sunlight or partial shade. Avoid placing Rinorea welwitschii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Rinorea welwitschii tolerates temperatures of 65–80°F. Rinorea welwitschii prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, slightly acidic soil with high organic content. Good drainage is essential for Rinorea welwitschii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Rinorea welwitschii 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 filtered sunlight or partial shade and well-draining, slightly acidic soil with high organic content. Avoid low spots where water collects after rain.

Rinorea welwitschii 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.

Rinorea welwitschii 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 Rinorea welwitschii 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.

Rinorea welwitschii 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.

Rinorea welwitschii can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to rinorea abbreviata plant care, which shares the same genus.

Rinorea welwitschii 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.

Rinorea welwitschii grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Rinorea welwitschii is native to Africa. In cooler regions, grow Rinorea welwitschii as a houseplant or bring it indoors before the first frost.
