In temperate zones, you can sow seeds directly into soil in April-May or September-October. Seeds are cold-hardy and germinate at +5-10°C. For earlier blooming (May-June), sow in March through seedlings.
During active growth — 2-3 times per week. Cornflower is drought-tolerant and dislikes excess moisture. Water when the top soil layer dries. Increase watering during heat, but ensure water doesn't stand.
Cornflower is undemanding and grows well in poor soil. During the growing season, fertilize every 2-3 weeks with complete mineral or diluted organic fertilizer. During flowering, use fertilizers with high phosphorus (P) and potassium (K) content.
Regularly deadhead spent flowers — this stimulates new buds and extends blooming from June to October. Cut flowers early morning when fully open for bouquets.
Yes, cornflower self-seeds easily. Wait for flower heads to fully dry on the plant, then collect seed pods. Dry them in a cool, well-ventilated place and store in paper bags until next spring.
