Home cultivation methods and precautions for cornflowers

Farming methods

Pot soil requirements

Cornflowers prefer loose, fertile, well-drained sandy loam. Therefore, the soil in the cornflower pot should be well-drained and ventilated. If the soil is too sticky, you can mix it with sawdust or pearl stone to improve it. A mixture of garden soil, leaf mold, wood ash, etc. is the best choice for cornflower potting soil.

Light Control

Cornflower is a long-day plant that requires a longer period of light, so be sure to place the cornflower in a sunny place in winter.

In winter, the daylight hours are relatively short, and sometimes cannot meet the needs of cornflowers themselves. You can use plant lights to supplement the lighting at night to help them bloom earlier.

The sunlight is strong in the summer, so cornflowers should not be placed in direct sunlight. Pay attention to shading and just let them receive some scattered light.

Water and fertilizer regulation

It is actually enough to water cornflowers once a day, but in the drier summer, you should water them more often, usually once in the morning and once in the evening, to keep the soil moist. This can also lower the temperature of the potted plants, but be careful not to allow water to accumulate.

Cornflowers like a lot of fertilizer. If the leaves grow too lush, the amount of nitrogen fertilizer should be reduced appropriately, and more phosphorus and potassium fertilizers should be applied before flowering to make it bloom large and beautiful flowers.

Pest and disease control

Cornflowers have fewer insect pests. Just pay attention to water control, apply fertilizer appropriately, increase light and maintain ventilation. In serious cases, increase the spraying of insecticides appropriately.

Breeding precautions

Avoid overcrowding

The stems of cornflowers are very thin and weak, and they easily fall over. We must prevent them from growing too densely and causing lodging due to poor ventilation.

Pay attention to proper fertilization

Liquid fertilizer should be applied once every 20 days during the growing season, but care should be taken not to apply too much nitrogen fertilizer. Instead, more phosphorus and potassium fertilizers should be applied. This will make the stems firm and produce brightly colored flowers.

Pay attention to watering

At the same time, watering should be moderate. Too much watering will cause root rot and affect the normal growth of the plant.
