How to grow Corn-cockle
It is best to sow Corn-cockle at a depth of 1/4 cm, with a spacing of 22 to 30 cm, in early spring after the last frost as occurred. Agrostemma prefers to grow in full sunlight. The soil should ideally be a rich loam, though the plant is capable of surviving in most soils. Agrostemma requires between two or three weeks for germination to occur. If initiating growth indoors then it is best to sow at a temperature of thirteen to eighteen degrees Centigrade seven or eight weeks before planting outdoors in the early spring or late autumn in milder climates.
