Queensland Maple Plant Care

Queensland Maple (Flindersia brayleyana) belongs to the Rutaceae family within the Flindersia genus. Queensland Maple is native to northern Queensland. Queensland Maple is also known as Maple Silkwood, Maplewood, Silkwood.

Queensland Maple displays a tall, upright tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Queensland Maple produces small white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Queensland Maple 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.

Queensland Maple thrives in full sun to partial shade.

Flindersia brayleyana tolerates temperatures of 60–85°F. Queensland Maple prefers humidity levels of 40–70%.

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

Feed Queensland Maple 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 loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Queensland Maple 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.

Queensland Maple can spread to about 15 ft (4.6 m) and reach about 30 ft (9 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 Queensland Maple 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.

Queensland Maple 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.

Queensland Maple can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to silver ash plant care, which shares the same genus.

Queensland Maple is susceptible to scale insects, citrus leaf miner. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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