Planting Windows

Spring Planting: Sow directly outdoors after the last frost date when soil reaches 60-70°F (15-21°C). Planting in early to mid spring supports early summer blooms. Germination typically occurs within 7-14 days, giving you a rapid color payoff to kick off the season.

Fall Planting: In milder winter climates, sow in autumn for a jumpstart on spring color. These seeds will overwinter and germinate in early spring; young seedlings can tolerate light frosts, providing a robust start for next season's display.

How to Plant

Direct Sowing Quick Start: Prepare soil by loosening 6-8 inches and mixing in compost or organic matter to improve drainage. Sow seeds ½ inch deep and about 2 inches apart. Lightly cover with soil and water gently. Maintain consistent moisture until germination in 7-14 days. This method mirrors the plant’s natural self-seeding habit and minimizes effort.

Indoor Starting Quick Start: Start indoors 6-8 weeks before the last frost using a seed starting mix. Plant 3-4 seeds per cell, cover with ½ inch soil, and keep temperatures around 60-70°F. Once seedlings emerge, provide bright light and transplant outdoors when they reach 2-4 inches tall.

Care & Growing Conditions

• Light & temperature: full sun with at least 6 hours of direct light daily; tolerates 60-80°F once established.
• Soil & spacing: sandy or loamy soil with good drainage; neutral to slightly alkaline pH (6.0-7.5); thin to 6-12 inches apart for good air circulation.
• Moisture: keep soil consistently moist during germination and early growth, avoiding waterlogged conditions.

Why Gardeners Choose Black Cornflower
