How to Germinate Bell Flower Seeds 

Sowing Indoors

1. Timing: Start seeds indoors at any time of the year, as long as you can provide sufficient warmth and light. 
2. Preparation: Use a well-draining seed compost and spread the seeds evenly across the surface. Lightly press the seeds into the compost without fully covering them, as they require light to germinate. 
3. Temperature: Maintain a consistent temperature between 12–20°C (54–68°F) for optimal germination. 
4. Moisture: Keep the soil moist but not waterlogged. Excess moisture can reduce germination success. 
5. Location: Place pots or trays in a sunny location, such as a windowsill or conservatory, to provide the light required for germination. 

Sowing Outdoors

1. Timing: Sow seeds outdoors from January to April, once stable weather conditions are present and the risk of frost has passed. 
2. Preparation: Choose a sunny, well-draining location. Loosen the soil and remove any debris before sowing. 
3. Depth: Press seeds lightly into the soil surface, ensuring they remain exposed to light. 

Germination Period

• Seeds typically germinate within 7–14 days under optimal conditions. 
• Keep the soil consistently moist during this period to encourage successful germination. 

Transplanting

1. Once seedlings reach approximately 7 cm in height, they can be transplanted to their final growing location. 
2. Gradually acclimatise indoor-grown seedlings to outdoor conditions over 7–10 days before planting out. 
3. Ensure well-drained soil and select a location that receives plenty of sunlight. 

Care and Maintenance

• Watering: Platycodon thrives in well-drained soil. Avoid overwatering but keep the soil moist during dry periods. 
• Fertiliser: Apply a balanced, all-purpose fertiliser once during the growing season to encourage healthy blooms. 
• Deadheading: Remove spent flowers regularly to prolong the blooming period and encourage new growth. 
• Winter Care: Although hardy, Platycodon benefits from a layer of mulch in colder months to protect the roots.
