Gompholobium knightianum Plant Care

Gompholobium knightianum (Gompholobium knightianum) belongs to the Fabaceae family within the Gompholobium genus. Gompholobium knightianum is native to the south-west of Western Australia.

Gompholobium knightianum displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Gompholobium knightianum produces bright yellow pea-like flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Gompholobium knightianum every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Gompholobium knightianum thrives in full sun to partial shade.

Gompholobium knightianum tolerates temperatures of 50–80°F. Gompholobium knightianum prefers humidity levels of 40–70%.

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

Feed Gompholobium knightianum every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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.

Gompholobium knightianum is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Gompholobium knightianum can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Gompholobium knightianum 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 shrub in one year.

Gompholobium knightianum 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.

Gompholobium knightianum can be propagated through seeds, cuttings. Similar propagation techniques also apply to native wisteria plant care, which shares the same genus.

Gompholobium knightianum is susceptible to aphids, leafhoppers, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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