Tips for Growing Cornflower from Seed

Cornflower is an easy-to-grow plant that can be directly sown from April to mid-June. For early flowers, sow seeds in the greenhouse in autumn or early spring, as this plant is very cold-tolerant. To grow cornflowers as cut flowers and extend your harvesting window, sow twice: once in autumn or early spring, and again in early May. You can also start seeds in trays to save garden space.

When to Pick the Flowers

To get the longest vase life, harvest individual flowers when the buds are about halfway open. For larger branches, cut stems when most of the buds are colored. You can enjoy the flowers at home for up to 7 days. While they may not have the longest vase life, their beauty makes them a worthy addition to any bouquet.

Growing Tips

Cornflower Classic Magic thrives in moderately rich soil. Avoid excessive fertilization, which can lead to more leaves than flowers. These plants can reach up to 90 cm tall, so providing gentle support can help maintain a tidy appearance and prevent stems from bending.

By following these tips, you can enjoy a continuous supply of beautiful cornflowers, perfect for adding charm to your garden and bouquets.
