Cornflower likes sunny growing environment and can't stand shade. When it is cured at ordinary times, in order to make it grow well, it can be put under normal light. However, it should be noted that although I like sunshine very much, I don't need too much planting spacing. If the spacing is too large, it will grow badly.
Its roots are very developed, even in poor soil can grow, but in order to promote healthy growth, it is best to provide soft texture, good drainage soil, not to produce too much water.
Cornflower is able to bear cold, like cold growth environment, can not stand hot climate. It can be planted in the open in East China, and it needs to be covered in North China for winter.
It is suitable for growing in humid environment, but it can't stand water humidity. Generally, water can be given once a day. In summer, when it is very dry, there is more water demand, which can be supplied once in the morning and once in the evening.
It likes fertilizer. It needs to apply fertilizer every month during its growth and development period, and all elements should be balanced. If the branches and leaves are very lush, nitrogen application can be reduced. Before flowering, apply more P and K fertilizer to ensure good flowering.
