Growing Corncockle is quite easy, and there is not much effort involved. Start sowing Corncockle in the spring in the location where it is to be grown. Do not start the seeds in a planter to transplant later. Germination time for Corncockle should be about 2 or 3 weeks.
For best results, plant and grow Corncockle in a rich, loose soil. Make sure it is well-drained. Corncockle tends to grow in most types of soils though. Keep the plant in a sunny area.
Corncockle is a very hardy plant, withstanding temperatures down to about -20 degrees celsius. Not that you have much control over the cold temperatures, but do not let the temperature get colder than this. If you live in a colder area of the world, do not expect Corncockle to survive very long into the autumn season.
