Growing Notes

• Use clean, fine, freely drained seedling mix. Surface-sow and mist the pellet until its coating softens; never bury it.
• Keep the surface evenly moist and humid only until emergence, then provide bright light and airflow.
• Move seedlings at about three true leaves and harden them gradually for 7–10 days before planting outside.
• Plant at the exact spacing above in fertile, freely drained soil and water at the root.
• Shelter double blooms from hard rain, water at the root and remove collapsed flowers promptly.
