It can be placed in a sunny place in about 7 days. In the growth period, liquid organic fertilizer or compound fertilizer should be applied every half a month until the flowering period, so as to keep the soil moist and ventilated.

Combine organic fertilizer with inorganic fertilizer, increase the total amount of phosphorus, potassium and nitrogen, but pay attention to the application of nitrogen fertilizer in different times. In seedling stage, the base fertilizer should be applied in depth, and the soil with good drainage and permeability and deep and loose soil layer should be selected. After that, no fertilizer should be applied. To the growth period, the use of less fertilizer times more ways to fertilize, for growth needs.
