Creeping Grevillea Plant Care

Creeping Grevillea (Grevillea humifusa) belongs to the Proteaceae family within the Grevillea genus. Creeping Grevillea is native to a restricted area of the south-west of Western Australia.

Creeping Grevillea displays an upright, bushy shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Creeping Grevillea produces showy clusters of red, pink, or white flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Creeping Grevillea 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.

Creeping Grevillea thrives in full sun to partial shade.

Grevillea humifusa tolerates temperatures of 50–80°F. Creeping Grevillea prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Creeping Grevillea to prevent waterlogging, which leads to root rot and fungal issues.

Feed Creeping Grevillea 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 full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Creeping Grevillea 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.

Creeping Grevillea 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 Creeping Grevillea 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.

Creeping Grevillea 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.

Creeping Grevillea can be propagated through seeds, cuttings. Similar propagation techniques also apply to acacia grevillea plant care, which shares the same genus.

Creeping Grevillea 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.

Creeping Grevillea grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Creeping Grevillea is native to a restricted area of the south-west of Western Australia. In cooler regions, grow Creeping Grevillea as a houseplant or bring it indoors before the first frost.
