IMPORTANT TIPS
1.Cornflower seeds need complete darkness for germination to occur.
2.Allow the soil to dry out slightly between watering. Do not allow the soil to become too dry, or the plants may flop over. However, cornflower is drought tolerant and will easily spring back from under watering.
3.Feed cornflowers once per month during the spring and summer months using a balanced flower fertilizer. Refer to the manufacturer’s instructions for proper dosage, and apply half the recommended dose. Cornflower can be invasive if the soil is too fertile, so avoid over-fertilizing.
4.Remove spent flowers as they fade to encourage the growth of new flowers, prolong the blooming period of the cornflower plants and decrease the number of self-sown seedlings.
