When and Where to Sow Double Pink Cornflower Seeds
- Indoor Sowing: Start seeds indoors in early spring (March to April) on a sunny windowsill or in a greenhouse where consistent warmth is available.
- Outdoor Sowing: Directly sow seeds outdoors after the risk of frost has passed (April to June) and the ground is workable.
How to Sow Double Pink Cornflower Seeds
- Soil Preparation: Choose a sunny spot with well-drained soil. Cornflowers thrive in most soil types, but for optimal growth, use neutral or slightly alkaline soil. Loosen the soil to a fine tilth and remove any weeds or debris. If sowing in containers, use a high-quality, well-draining compost.
- Sowing Depth and Spacing: Sow seeds 1/8″ to 1/4″ (3-6 mm) deep, ensuring they are fully covered with soil, as cornflowers require darkness for germination. Space seeds 10″ to 12″ (25-30 cm) apart to allow for proper air circulation and room to grow.
- Watering: Water the area gently after sowing to settle the soil. Maintain consistent moisture during the germination period, but avoid waterlogging.
- Germination Conditions: Ideal germination temperatures are between 15-20°C (59-68°F). Seeds typically germinate within 5 to 10 days.
- Transplanting: Once seedlings reach 2″ to 3″ in height, thin or transplant them to their final growing location, maintaining proper spacing.
Caring for Double Pink Cornflower Plants
- Watering: Water regularly, especially during dry periods, to keep the soil moist but not soggy. Established plants can tolerate periods of drought.
- Deadheading: Remove spent blooms regularly to promote continuous flowering throughout the summer.
- Support: In windy areas, provide light support, such as garden stakes, to prevent tall stems from bending or breaking.
- Feeding: Cornflowers typically do well without fertilizer, but for an extra boost, apply a general-purpose fertilizer sparingly during the growing season.
