How to care for Centaurea cyanus White Ball:
Centaurea prefer poorer soils, so do not use fertiliser. Support taller stems faded flower heads down to the ground and compost the dead stems. Seeds sown in autumn and over-wintered in a cold frame will produce plants that will flower earlier in the year than those sown in spring.
Sowing instructions:
Surface-sow seeds in trays filled with good quality compost, and germinate at 50-61°F (10°C-16°C). Pot on when they have put on their first true leaves and harden off before planting out after the frosts have passed. Alternatively, sow directly in late spring or early summer, and thin out to 30cm as they grow.
