Growing Notes

• Pre-moisten fine seedling mix, wet the coating completely and keep it evenly moist without waterlogging.
• 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.
