Sloanea woollsii Plant Care

Sloanea woollsii (Sloanea woollsii) belongs to the Elaeocarpaceae family within the Sloanea genus. Sloanea woollsii is native to northeastern NSW and eastern Queensland, Australia.

Sloanea woollsii displays a tall tree, spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Sloanea woollsii produces small, inconspicuous greenish-white flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Sloanea woollsii 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.

Sloanea woollsii thrives in partial to full sun.

Sloanea woollsii tolerates temperatures of 60–80°F. Sloanea woollsii prefers humidity levels of 50–80%. 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 Sloanea woollsii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sloanea woollsii 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with partial to full sun and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Sloanea woollsii 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.

Sloanea woollsii can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Sloanea woollsii 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.

Sloanea woollsii 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.

Sloanea woollsii can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to yellow carabeen plant care, which shares the same genus.

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

Sloanea woollsii grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Sloanea woollsii is native to northeastern NSW and eastern Queensland, Australia. In cooler regions, grow Sloanea woollsii as a houseplant or bring it indoors before the first frost.
