Garcinia warrenii Plant Care

Garcinia warrenii (Garcinia warrenii) belongs to the Clusiaceae family within the Garcinia genus. Garcinia warrenii is native to New Guinea, the Torres Strait Islands, northeastern Queensland from Cape York Peninsula south to Babinda, and a small, isolated population on Melville Island in the Northern Territory, Australia.

Garcinia warrenii displays a small to medium-sized tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Garcinia warrenii produces small, fragrant white flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Garcinia warrenii 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.

Garcinia warrenii thrives in full sun to partial shade.

Garcinia warrenii tolerates temperatures of 60–85°F. Garcinia warrenii prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

Feed Garcinia warrenii 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 full sun to partial shade and well-draining, slightly acidic soil with high organic content. Avoid low spots where water collects after rain.

Garcinia warrenii 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.

Garcinia warrenii can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Garcinia warrenii 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.

Garcinia warrenii 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.

Garcinia warrenii can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to cowa fruit plant care, which shares the same genus.

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

Garcinia warrenii grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Garcinia warrenii is native to New Guinea, the Torres Strait Islands, northeastern Queensland from Cape York Peninsula south to Babinda, and a small, isolated population on Melville Island in the Northern Territory, Australia. In cooler regions, grow Garcinia warrenii as a houseplant or bring it indoors before the first frost.
