Growing Tips for New Zealand

Sow seeds in spring after the last frost or start indoors in August–September for an early start. Surface sow as seeds need light to germinate — press gently onto moist seed-raising mix and keep warm. Transplant seedlings to a sunny or lightly shaded position with well-drained soil. Water regularly and deadhead spent blooms to encourage continuous flowering. Ageratum thrives in NZ's warm summers and will flower prolifically from November through to autumn.
