Growing Tips for New Zealand

Cosmos sulphureus loves warmth and performs best in full sun with well-drained soil. Sow seeds directly in spring once soil has warmed, or start indoors 3–4 weeks before transplanting. Sow on the surface of moist seed-raising mix and cover lightly. Space plants 25–30 cm apart. Sulphureus types thrive in drier conditions and are more heat-tolerant than bipinnatus — avoid overwatering. Deadhead regularly to keep plants flowering prolifically from summer through to autumn. Performs beautifully throughout NZ in warm, sunny positions.
