What Soil Mix Works Best for a Smallhead Dubautia?

Well-draining sandy soil with added organic matter for moisture retention. Good drainage is essential for Smallhead Dubautia to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Smallhead Dubautia?

Feed Smallhead Dubautia 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 Smallhead Dubautia?

Choose a spot with full sun to partial shade and well-draining sandy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

How Far Apart Should You Plant a Smallhead Dubautia?

Smallhead Dubautia 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.
