Growing, Harvesting and Storage

Platycodon grandiflorus grows in well-drained, loamy soil that is rich in organic matter, preferring full sun to partial shade for optimal growth.

It thrives in temperate climates with moderate rainfall, requiring regular watering during dry periods but avoiding waterlogging to prevent root rot. Regular pruning of spent flowers and dead foliage promotes vigorous growth and enhances the plant's medicinal potency. The best time to harvest platycodon is in late summer to early autumn, when the roots are most mature and contain the highest concentration of active compounds; the roots should be carefully dug up with a spade to avoid damage.

After harvesting, the roots are washed, sliced, and dried in a cool, well-ventilated area or in a dehydrator, then stored in airtight containers in a cool, dark place to preserve their potency and extend their shelf life.
