Retiniphyllum chloranthum Plant Care

Retiniphyllum chloranthum (Retiniphyllum chloranthum) belongs to the Rubiaceae family within the Retiniphyllum genus.

Retiniphyllum chloranthum displays a compact, upright shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Retiniphyllum chloranthum produces small white fragrant flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Retiniphyllum chloranthum 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.

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

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

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

Feed Retiniphyllum chloranthum 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 acidic soil with high organic content. Avoid low spots where water collects after rain.

Retiniphyllum chloranthum is suited to USDA Zone 13b.

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.

Retiniphyllum chloranthum can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Retiniphyllum chloranthum 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.

Retiniphyllum chloranthum 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.

Retiniphyllum chloranthum can be propagated through softwood cuttings, air layering. Similar propagation techniques also apply to retiniphyllum cataractae plant care, which shares the same genus.

Retiniphyllum chloranthum 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.

Retiniphyllum chloranthum grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. In cooler regions, grow Retiniphyllum chloranthum as a houseplant or bring it indoors before the first frost.
