• 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.
• Use pots or beds with airflow and shelter the large grandiflora flowers from repeated hard rain.
