Rough Bush-pea Plant Care

Rough Bush-pea (Pultenaea scabra) belongs to the Fabaceae family within the Pultenaea genus. Rough Bush-pea is native to south-eastern continental Australia.

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

Leaf size: approximately 4 inches.

Water a young or newly planted Rough Bush-pea 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.

Rough Bush-pea thrives in full sun to partial shade.

Pultenaea scabra tolerates temperatures of 50–80°F. Rough Bush-pea prefers humidity levels of 40–70%.

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

Feed Rough Bush-pea 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.

Rough Bush-pea 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.

Rough Bush-pea 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 Rough Bush-pea 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.

Rough Bush-pea 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.

Rough Bush-pea can be propagated through seeds, cuttings. Similar propagation techniques also apply to needle bush-pea plant care, which shares the same genus.

Rough Bush-pea is susceptible to aphids, caterpillars, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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