Quick Grow Facts

• Plant type: Cool-season annual; may be short-lived in mild frost-free conditions

• Position: Full sun; light afternoon shade in very hot districts
• Depth and light: Cover individual fine seeds very lightly. If sowing a multi-seed pellet, use a thicker, loose vermiculite layer and enough water to dissolve it. Give bright light after emergence.

Growing Notes

• Pre-moisten fine seedling mix and keep it evenly moist without waterlogging. If using multi-seed pellets, sow each one whole; do not crush it or place several pellets in one small cell.
• Transplant the small clump once roots hold the plug together; do not pull every seedling apart.
• Harden plants over 5–7 days and trim after a flower flush to encourage fresh bloom.
• The mixture contains separately coloured plants; one seed does not produce a multicoloured plant.
