Pull up the weeds, and then carry out cultivating to loosen the soil. Take care not to damage the roots of Chinese cabbage in cultivating, and pay attention to combining soil cultivating with cultivating.

Ditches should be opened for drainage to prevent the Chinese cabbage from being flooded and causing pests and diseases. The growth of leafy vegetables such as Chinese cabbage is inseparable from fertilizers. If the base fertilizer is insufficient, the growth of the seedlings will be weak. You can topdress 20-30kg MAINPAR NPK 16-6-26 per mu. After fertilizing, water according to the soil moisture.

Three, pest control
