What Soil Mix Works Best for a Otholobium pubescens?
Well-draining sandy loam with added organic matter. Good drainage is essential for Otholobium pubescens to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Otholobium pubescens?
Feed Otholobium pubescens 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 Otholobium pubescens?
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.

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 Otholobium pubescens?
Otholobium pubescens can spread to about 2 ft (0.6 m) and reach about 2 ft (0 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 Otholobium pubescens?
Prune Otholobium pubescens while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
