|When to sow
|March - April and September - October.
|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.
|June to August.
