What Soil Mix Works Best for a Gompholobium pinnatum?

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

How Often Should You Fertilize a Gompholobium pinnatum?

Feed Gompholobium pinnatum 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.

Where Should You Plant a Gompholobium pinnatum?

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 pinnatum 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.

How Far Apart Should You Plant a Gompholobium pinnatum?

Gompholobium pinnatum 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.

How Do You Prune a Gompholobium pinnatum?

Prune Gompholobium pinnatum 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.
