Water regularly especially during dry periods. Germination should take up to 21 days. Once the Cornflowers are large enough to handle, thin them out to 15cm apart.
    Alternatively you can grow your Cornflowers indoors from August to September for an early summer flowering the next year. Sow on the surface of good quality compost at a temperature of up to 23C and cover finely with compost or vermiculite. Do not exclude light as this helps with the germination process. When large enough to handle, transplant into cooler conditions until they are large enough to plant outdoors.
