1、 Sow

Before sowing, apply enough base fertilizer in the soil and cover it with one centimeter of soil after sowing. Spring sowing is mostly from March to April, and autumn sowing is from August to September

2、 Temperature

It is necessary to provide a 17-20 ℃ growth environment for South chrysanthemum. The weather is still relatively cold after sowing in early spring, so a layer of film should be covered to keep warm. It can be opened after the weather is warm. The temperature should not be higher than 25 ℃, and ventilation should be strengthened after it is higher than this temperature

3、 Weeding

When the seedlings grow to about 10 cm, weeds should be removed in time

4、 Watering and fertilization

The watering times and amount must be well controlled. Just keep the soil moist. Apply quick acting nitrogen fertilizer 10-15 days before harvest
