What Soil Mix Works Best for a Flax-leaved Candytuft?

Feed Flax-leaved Candytuft 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.
