What Soil Mix Works Best for a Blue-leaved Currant?

Well-draining sandy soil mix with added compost for nutrients. Good drainage is essential for Blue-leaved Currant to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Blue-leaved Currant?

Feed Blue-leaved Currant 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 Blue-leaved Currant?

Choose a spot with full sun to partial shade and well-draining sandy soil mix with added compost for nutrients. Avoid low spots where water collects after rain.

Blue-leaved Currant is suited to USDA Zone 12a – 11b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

How Far Apart Should You Plant a Blue-leaved Currant?

Blue-leaved Currant can spread to about 6 ft (1.8 m) and reach about 4 ft (1 m) tall. Space plants about 6 ft (1.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.
