Cut flowers in the morning when stems are fully hydrated. For best results, cut long stems and remove green foliage below the water line before arranging. To save seeds, allow flower heads to fully ripen and dry on the plant, then pluck the dried heads and squeeze them gently in your palm to release the seeds.
Deadhead spent flowers regularly to encourage continuous blooming throughout the season. This practice is essential for sustained production and keeps plants looking tidy.
