Uvaria scabridula Plant Care

Uvaria scabridula (Uvaria scabridula) belongs to the Annonaceae family within the Uvaria genus. Uvaria scabridula is native to Cape York Peninsula, Queensland, Australia.

Uvaria scabridula displays a small tree or shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Uvaria scabridula produces showy, fragrant flowers in shades of white, yellow, or pink.

Leaf size: approximately 6 inches.

Water a young or newly planted Uvaria scabridula 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.

Uvaria scabridula thrives in partial shade to full sun.

Uvaria scabridula tolerates temperatures of 65–85°F. Uvaria scabridula prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Uvaria scabridula to prevent waterlogging, which leads to root rot and fungal issues.

Feed Uvaria scabridula 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 partial shade to full sun and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Uvaria scabridula is suited to USDA Zone 13b.

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.

Uvaria scabridula can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Uvaria scabridula 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.

Uvaria scabridula 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.

Uvaria scabridula can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to uvaria chamae plant care, which shares the same genus.

Uvaria scabridula 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.

Uvaria scabridula grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Uvaria scabridula is native to Cape York Peninsula, Queensland, Australia. In cooler regions, grow Uvaria scabridula as a houseplant or bring it indoors before the first frost.
