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.
