What Soil Mix Works Best for a Bastard Rosewood?

Well-draining, rich loamy soil with added organic matter. Good drainage is essential for Bastard Rosewood to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Bastard Rosewood?

Feed Bastard Rosewood every 8 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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.

How Far Apart Should You Plant a Bastard Rosewood?

Bastard Rosewood can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.
