How to Sow Double Pink Cornflower Seeds 

Soil Preparation

1. Prepare well-drained soil in pots, trays, or garden beds. Cornflowers tolerate most soil types but prefer a neutral pH and well-worked soil. 
2. Rake the soil to create a fine tilth, removing debris and weeds. 

Sowing Depth and Spacing

1. Sow seeds at a depth of 1/8″ to 1/4″, ensuring they are fully covered, as they require darkness to germinate. 
2. Space seeds 10″ to 12″ apart to allow adequate room for growth. 

Watering 

• Water the soil lightly to keep it consistently moist but not waterlogged during the germination period. 

Germination Conditions

1. Cornflower seeds germinate best at temperatures between 15-20°C (59-68°F). 
2. Germination typically takes 5 to 10 days under ideal conditions. 

Transplanting 

• Once seedlings are 2″ to 3″ tall, they can be transplanted to their final growing location. Ensure adequate spacing to encourage healthy growth and airflow. 

Caring for Double Pink Cornflower Plants 

• Watering: Water regularly but avoid overwatering, as cornflowers prefer well-drained soil. 
• Deadheading: Remove spent blooms to encourage prolonged flowering throughout the summer. 
• Support: Taller plants may require light support to prevent stems from bending, especially in windy areas. 
• Feeding: Fertilization is not typically necessary, but a light application of balanced fertilizer can promote healthy blooms if desired.
