Water regularly to keep the soil consistently moist, especially during dry spells. Avoid waterlogged conditions, which can lead to root rot.

Allow the top inch of soil to dry out slightly between waterings for optimal growth. Reduce watering in cooler months.

Deadheading spent flowers encourages continuous blooming throughout the summer. Cut back plants after flowering to prevent self-seeding if unwanted, or to tidy up their appearance.

Light trimming can also help maintain a more compact shape.

Easily grown from seeds sown directly outdoors in early spring or in autumn. Seeds can also be started indoors about 4-6 weeks before the last frost. Transplant seedlings gently into their final positions.

As annuals, Cornflowers are typically not repotted. If grown in containers, they are usually replaced each year.

For perennial varieties or if you are overwintering them, repot in spring into a slightly larger container with fresh potting mix.
