Outdoor planting

In areas south of central China, cornflowers do not need to take cold protection measures and can survive the winter directly in the open field. But in North China, it is necessary to cover with cold-proof materials in winter. In winter, cornflowers can be continuously buried in the soil for the winter, and then taken out in early spring of the next year for pot transplantation. Because the lateral roots of cornflower are rarely intolerant to transplantation, soil balls must be brought when transplanting, otherwise they will not survive easily. Apply 5 times the amount of decomposed fertilizer at intervals of 10 days or 1 month until March of the following year to wait for flowering.

Indoor potted plants

Potted cornflowers require fertile and loose potting soil. It is best to mix plant ash with garden soil and mold leaves to mix with the potting soil. Fertilize frequently until flower buds appear. Or let cornflowers enter the house in advance before winter. The room temperature needs to be maintained at 8 to 15 degrees Celsius, and watering should be done appropriately. Place it in a sunny location and apply a small amount of thin compound fertilizer. Then, just wait for it to bloom.
