How to grow Polka Dot Mix Cornflower seeds

Choose Your Planting Method

• Outdoors: Direct sow in early spring as soon as the soil can be worked — cornflowers dislike root disturbance.
• Indoors: Start 2–4 weeks before the last frost in plantable pots if you want earlier blooms.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Spray bottle for misting

Sowing the Seeds

• Sow about 1/4 inch (5 mm) deep and cover lightly with soil.
• No pre-treatment is needed.

Provide the Right Conditions

• Light: Bright light after emergence.
• Temperature: 59–64°F (15–18°C); cool soil gives the best germination.

Germination

• Seedlings emerge in 7–14 days.
• Keep the soil evenly moist until sprouts appear.

Transplanting

• Direct sowing is recommended; disturb roots as little as possible.
• Thin or space plants 6–12 inches apart.

Care Tips

• Sun: Full sun for the sturdiest stems and most flowers.
• Water: Moderate; cornflowers do well in average, well-drained soil.
• Fertilizer: Average soil is fine; no heavy feeding needed.
• Deadhead to prolong bloom, and sow every few weeks for a succession of flowers.

Bloom Time:

Summer to early fall.
