Red Cinchona Plant Care

Red Cinchona (Cinchona succirubra) belongs to the Rubiaceae family within the Cinchona genus. Red Cinchona is native to Central and South America. Red Cinchona is also known as Peruvian Bark, Quina Bark.

Red Cinchona displays a small tree or shrub growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Red Cinchona produces small, fragrant white or pink flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Red Cinchona every 7–14 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.

Red Cinchona thrives in partial shade to full sun.

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

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

Feed Red Cinchona 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, slightly acidic soil with good organic content. Avoid low spots where water collects after rain.

Red Cinchona is suited to USDA Zone 13a.

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.

Red Cinchona can spread to about 10 ft (3 m) and reach about 15 ft (5 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Red Cinchona 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.

Red Cinchona 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.

Red Cinchona can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to calisaya bark plant care, which shares the same genus.

Red Cinchona 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.

Red Cinchona grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Red Cinchona is native to Central and South America. In cooler regions, grow Red Cinchona as a houseplant or bring it indoors before the first frost.
