Regular thinning ensures strong plants with beautiful flowers perfect for cutting or edible uses.
Organic cornflowers thrive best in full sunlight and well-drained soil, where they can reach heights of 30 to 90 cm. Regular watering keeps the soil moist but not waterlogged, promoting continuous blooming from June to September. Deadheading spent flowers encourages fresh blossoms and extends flowering time. These annuals attract beneficial pollinators like bees and butterflies, enhancing garden biodiversity. To maintain plant health, avoid overcrowding by allowing enough space for air circulation. Their delicate blue petals not only brighten borders and naturalized areas but also make excellent cut flowers for indoor arrangements.
