Step 1: Starting
Sow indoors 6-8 weeks before planting out. in peat pots or similar. Otherwise direct sow outdoors after the last frost date. Just cover the seeds. If starting indoors. provide bright light and a soil temperature of 18-21°C (65-70°F). China Aster seedlings are very susceptible to damping off. so provide good ventilation and only water from below.
