Northern Rosewood Plant Care

Northern Rosewood (Blepharocarya involucrigera) belongs to the Anacardiaceae family within the Blepharocarya genus. Northern Rosewood is native to Queensland, Australia.

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

Leaf size: approximately 6 inches.

Water a young or newly planted Northern Rosewood 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.

Northern Rosewood thrives in full sun to partial shade.

Blepharocarya involucrigera tolerates temperatures of 50–90°F. Northern Rosewood prefers humidity levels of 40–70%.

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

Feed Northern Rosewood 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 organic matter for moisture retention. Avoid low spots where water collects after rain.

Northern Rosewood is suited to USDA Zone 12a.

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.

Northern Rosewood 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 Northern Rosewood 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.

Northern Rosewood is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Northern Rosewood can be propagated through seeds, stem cuttings.

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

Northern Rosewood grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Northern Rosewood is native to Queensland, Australia. In cooler regions, grow Northern Rosewood as a houseplant or bring it indoors before the first frost.
