What Soil Mix Works Best for a Star Guinea Flower?

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Star Guinea Flower to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Star Guinea Flower?

Feed Star Guinea Flower 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.

How Far Apart Should You Plant a Star Guinea Flower?

Star Guinea Flower can spread to about 3 ft (0.9 m) and reach about 2 ft (0 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Star Guinea Flower?

Prune Star Guinea Flower while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
