Slender-fruited Hakea Plant Care

Slender-fruited Hakea (Hakea lissosperma) belongs to the Proteaceae family within the Hakea genus. Slender-fruited Hakea is native to parts of south eastern Australia. Slender-fruited Hakea is also known as Needlewood.

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

Leaf size: approximately 4 inches.

Water a young or newly planted Slender-fruited 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.

Slender-fruited Hakea thrives in full sun to partial shade.

Hakea lissosperma tolerates temperatures of 50–85°F. Slender-fruited Hakea prefers humidity levels of 40–70%.

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

Feed Slender-fruited 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.

Slender-fruited 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.

Slender-fruited 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 Slender-fruited 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.

Slender-fruited 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.

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

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