Cornflower is propagated by seeds, and is generally sown in August and September in warm land in Kannai, covered with open field for overwintering, planted in early spring the following year, and flowering in early summer. The Tohoku region is spring sown in greenhouses. Because the roots of cornflowers are straight roots and have few lateral roots, transplanting should be carried out with soil when the seedlings are small, and the seedlings are not easy to survive if they are large, so they are often seeded in spring.

Cornflowers can also be self-propagated. In addition, cornflowers prefer dense planting, otherwise they will grow poorly.
