Zizhucao has strict requirements on water. It likes humid environment and is afraid of drought, but it can't accumulate water. Therefore, it should be noted that in the dry season, more water is needed, and the air humidity should be increased by spraying water; in the rainy season, timely drainage is needed, because the plant is not waterlogged, and the water will have a bad impact on the growth of the plant.
Fertilization is also necessary. A certain amount of base fertilizer should be applied during the planting of zizhucao, in addition, topdressing should be done in time during the growing period. In spring and autumn, you can apply rotten farmyard manure. From April to October, you can apply thin manure every two months.

Sowing and propagation are carried out in March and April in spring, and transplanting can be carried out in autumn. Cutting propagation and branch propagation are also carried out in spring.
Zizhucao has strong resistance to disease and basically has no diseases and insect pests. However, during the vigorous growth period, there will also be insect pests, which can be killed manually or insecticides can be used.
