Growing Tips

Growing conditions

Cornflowers like to grow in well drained soil in full sun.

When to grow

Sow from March to May and they will flower from June to September.

What you need

  • A packet of cornflower seeds
  • Gardening gloves
  • A rake
  • A trowel
  • Plant label and pencil

How to grow

  1. Cornflowers can be sown straight in to the ground where they are going to flower, so make sure the space you are going to sow is weed free, by using a trowel to remove the weeds.
  2. Rake the soil to a fine tilth (so it's a fine, crumbly soil) and make some drills 12mm deep. The rows should be spaced about 30cm apart.
  3. Water the soil before sowing and allow the drill to drain if the soil is dry, sprinkle the seed in carefully and cover up with soil. As they grow, if the plants are crowded, then thin them out to about 30cm apart.
