Platycodon grandiflorum can be sown in the other three seasons except that it is not suitable to germinate in the high temperature in summer, but the best time is in mid-September and around the Beginning of Spring every year, when sowing helps to promote seed rooting and germination. enhance the growth ability of seedlings, improve yield and quality, it is best to use strip sowing, and timely cover fine soil and plastic film after sowing to improve soil water and fertilizer conservation. To prevent the loss of water and fertilizer and affect the germination rate of seeds, the plastic film should be opened in time after emergence to ensure the normal growth of seedlings.

3. Field management

When the seedlings grow to about 2 cm after breaking the soil, observe the growth and density of the seedlings, do a good job of thinning the seedlings in time, and then wait until the seedlings grow again, we can start to fix the seedlings, control the distance between the seedlings, prevent the growth from being too dense, pull out the weak seedlings of the dead seedlings, and then supplement the seedlings to ensure the yield. Weeds should be weeded regularly in the seedling stage of Platycodon grandiflorum to prevent excessive weeds leading to malnutrition of Platycodon grandiflorum.
