What Soil Mix Works Best for a Spectacular Smokebush?

Well-draining sandy soil with added organic matter for nutrients. Good drainage is essential for Spectacular Smokebush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Spectacular Smokebush 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.

Spectacular Smokebush can spread to about 2 ft (0.6 m) and reach about 3 ft (1 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.
