Queñua Plant Care

Queñua (Polylepis tarapacana) belongs to the Rosaceae family within the Polylepis genus. Queñua is native to small, scattered groupings along the mountainous borders of Argentina, Bolivia, Chile, and Peru.

Queñua displays a small, compact tree growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Queñua produces small, inconspicuous flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Queñua 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.

Queñua thrives in full sun to partial shade.

Polylepis tarapacana tolerates temperatures of 50–80°F. Queñua prefers humidity levels of 40–70%.

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

Feed Queñua every 8 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 full sun to partial shade and well-draining sandy soil with good organic content. Avoid low spots where water collects after rain.

Queñua is suited to USDA Zone 12a.

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.

Queñua 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 Queñua 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.

Queñua 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.

Queñua can be propagated through seeds, cuttings. Similar propagation techniques also apply to australian polylepis plant care, which shares the same genus.

Queñua 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.

Queñua grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Queñua is native to small, scattered groupings along the mountainous borders of Argentina, Bolivia, Chile, and Peru. In cooler regions, grow Queñua as a houseplant or bring it indoors before the first frost.
