Growing, Harvesting and Storage

Platycodon grandiflorus grows best in well-drained, loamy soil with a slightly acidic to neutral pH, in full sun to partial shade, and requires regular watering to maintain consistent moisture without becoming waterlogged.

It thrives in temperate climates and benefits from mulching to retain soil moisture and suppress weeds. Regular pruning of dead or damaged foliage and monitoring for pests like aphids and slugs help maintain plant health and encourage vigorous growth. The best time to harvest platycodon grandiflorus is in late summer to early autumn, when the roots are mature and the leaves begin to yellow, using a spade to carefully dig up the entire plant to avoid damaging the root system.

After harvesting, the roots should be washed, sliced, and dried in a cool, shaded area or using a dehydrator to preserve potency, then stored in airtight containers in a cool, dark place or refrigerated to maintain their medicinal properties.
