What Soil Mix Works Best for a Blackfruit Dysphania?

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

How Often Should You Fertilize a Blackfruit Dysphania?

Feed Blackfruit Dysphania 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.

Blackfruit Dysphania can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.
