Step-by-Step Guide to Sowing Pastel Baby Doll Seeds 

Indoor Sowing 

1. Prepare Containers: Fill seed trays, pots, or containers with fresh, well-draining compost. 
2. Sowing the Seeds: Sow seeds at a depth of 1/4 inch (6 mm) in the compost. Cover lightly with soil and water gently to moisten. 
3. Germination Conditions: Place containers in a bright location, such as a windowsill or greenhouse, with temperatures maintained between 15-20°C (59-68°F). Germination typically occurs within 14-28 days. 
4. Watering: Keep the compost consistently moist but not waterlogged during the germination period. 
5. Transplanting: Once seedlings are large enough to handle, harden them off by gradually acclimatising them to outdoor conditions for 7-10 days. Transplant to their final growing position, spacing them 15-20 cm apart. 

Outdoor Sowing 

1. Soil Preparation: Choose a sunny or partially shaded spot with well-drained soil. Loosen the soil and remove weeds to create a fine seedbed. 
2. Sowing the Seeds: Sow seeds directly into the soil at a depth of 1/4 inch (6 mm). Cover lightly with soil and water gently. 
3. Timing: Ensure the last frost has passed, and the ground is warm and workable before sowing outdoors. 
4. Thinning: Thin seedlings to 15-20 cm apart once they emerge, ensuring adequate space for growth and air circulation. 

Caring for Pastel Baby Doll Plants 

• Watering: Water regularly, keeping the soil moist but not overly wet. Avoid letting the soil dry out completely, especially during warmer weather. 
• Sunlight: Place plants in a sunny location or an area with partial shade to encourage healthy blooms. 
• Feeding: Apply a light, balanced fertiliser every 4-6 weeks during the growing season to promote vibrant flowers and strong growth. 
• Deadheading: Trim back the first flowers after they begin to fade. This encourages new growth and prolongs the blooming period.
