What Soil Mix Works Best for a Bernardia myricifolia?

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

How Often Should You Fertilize a Bernardia myricifolia?

Feed Bernardia myricifolia every 6 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 Bernardia myricifolia?

Bernardia myricifolia can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.
