Tree Hakea Plant Care

Tree Hakea (Hakea arborescens) belongs to the Proteaceae family within the Hakea genus. Tree Hakea is native to parts of northern Australia. Tree Hakea is also known as Hairy Hakea.

Tree Hakea displays an upright, bushy shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Tree Hakea produces showy clusters of small, colorful flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Tree Hakea 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.

Tree Hakea thrives in full sun to partial shade.

Hakea arborescens tolerates temperatures of 50–85°F. Tree Hakea prefers humidity levels of 40–70%.

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

Feed Tree Hakea 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 sandy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Tree Hakea 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.

Tree Hakea can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Tree Hakea 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.

Tree Hakea 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.

Tree Hakea can be propagated through seeds, cuttings. Similar propagation techniques also apply to coastal hakea plant care, which shares the same genus.

Tree Hakea 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.

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