Sow indoors 6 - 8 weeks before last frost date. Seedlings like heat and take 8-14 days to germinate at 20 –27 degrees Celsius. Transplant outdoors to a well-drained sunny location approximately two weeks after last frost. Celosia resents transplanting so handle gently and disturb the roots as little as possible. Give plants some room, spacing about 30cm apart. Cut flowers when fully developed. To dry flower heads, hang upside down in an airy dark location. Plants will self-seed freely.
