| Sowing/Flowering Info:
Feb-March, sow seeds in moist seed compost, under glass. Keep at 16°C. When seedlings are large enough to handle, transplant into pots and grow on. Acclimatise plants before planting out when danger of frost has passed. Plant out with 150cm of spacing, into well-prepared soil, fertilised with well-rotted manure. Keep feeding with general purpose fertiliser and keep well-watered and weed free.
Cut flowers regularly to keep plant flowering, as well as to prevent self-seeding. Mulch surrounding ground with straw in cold winters.
