|Where to sow||In early autumn surface-sow in trays of good seed compost and over-winter in a cold frame or greenhouse, thinning out and potting on as they grow. These can be planted out in spring and produce early flowers. Alternatively, shallow-sow directly into a well-prepared seedbed in spring, thinning out to 15cm.|
|What to do next||Water well until established.|
|Once the cornflower have finished flowering, leave a few plants to die down and self seed. Others can be pulled up and composted.|
|This plant will produce more flowers when grown in poor soils, so don’t over-fertilise. Pinching out the growing tips will encourage bushier growth.|
|Flowering period||June to August.|
