Yarri Plant Care

Yarri (Gyranthera caribensis) belongs to the Malvaceae family within the Gyranthera genus. Yarri is also known as Caribbee, Bulletwood.

Yarri displays a tall, upright shrub growth habit, reaching up to 5 ft tall with a spread of approximately 3 ft. Yarri produces large, showy blooms in various colors.

Leaf size: approximately 8 inches.

Water a young or newly planted Yarri 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.

Yarri thrives in full sun to partial shade.

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

Well-draining, loamy soil with added compost for nutrients. Good drainage is essential for Yarri to prevent waterlogging, which leads to root rot and fungal issues.

Feed Yarri 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 full sun to partial shade and well-draining, loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Yarri 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.

Yarri can spread to about 3 ft (0.9 m) and reach about 5 ft (2 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Yarri 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.

Yarri 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.

Yarri can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to gyranthera darienensis plant care, which shares the same genus.

Yarri is susceptible to aphids, spider mites, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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