When to sow: Mar-May
Spacing: 30x30cm
Helichrysum tips: Sow strawflowers in early spring indoors into modules, or into a seed tray and then prick out when large enough to handle. Only lightly cover the seeds with compost. Transplant outside in May once danger of frost has passed.
Alternatively, direct sow in May in shallow drills, 30cm apart, and thin to 30cm in the row.
