|How To Grow
Sprinkle seeds over soil, firm down gently and keep damp. Or sow in seed boxes, transplanting when large enough to handle. When seedlings emerge in 10-14 days, thin to 2cm (1in) apart. Plant out to flowering position when plants are large enough, being careful not to damage roots. Feed regularly and remove spent flower heads to encourage flowering. Protect from snails. Pinch out the early buds to encourage good, strong clumps.
