The seedling of Platycodon grandiflorum can be transplanted in April to June(5 gallon pots). The early seedling has little influence on the quality of the seedling, and the late seedling has great influence on the transplanting.
Platycodon grandiflorum is afraid of ponding. When the height of soil is 5-7cm, the seedlings should be fixed at the same time(72 cell plug trays supplier). When there are dense seedlings and weak seedlings, the seedlings should be fixed according to the distance of 6-10cm. Platycodon grandiflorum is planted in autumn and spring(10 gallon plant pots wholesale).

It is not necessary to remove too many seedlings for proper thinning by wide strip sowing(72 cell propagation trays wholesale). Proper close planting is the key to increase production. In order to prevent and control aphid wax, we can apply 1kg of a-di powder per ton when turning over the farm manure, mix it evenly with the farm manure, and then apply it before turning over the field, and turn it into the field more than 30cm deep(1 gallon pots manufacturer), and level the harrow. the growth period is 2 years.(cheap 1 gallon plastic nursery pots suppliers china)
