Daily maintenance at home, can be placed on the balcony maintenance, so that the light can be irradiated, especially in winter, the intensity of sunlight itself is weak, the time is relatively short, so can be exposed to full light. Summer sun is too strong, or need to pay attention to, do not put in the direct sunlight.
The growth of cornflower can not be separated from the application of water. In the period of vigorous growth, it needs to be watered once a day. In summer, it evaporates vigorously, and it is relatively dry, so it needs to be watered more to keep moist. However, water should not be applied too much to prevent excessive accumulation of water, otherwise it will lead to rotten roots.
It prefers fertilizer. It needs to keep enough fertilizer in the period of vigorous growth. It can apply liquid fertilizer once every 20 days, but the concentration cannot be too high. Before flowering, a little more P and K fertilizer should be applied to ensure that the flowers bloom.
In the maintenance period, the temperature also needs to pay attention to, keep at about 20 degrees more appropriate
