Growing, Harvesting and Storage

Corydalis yanhusuo grows in well-drained, loamy soil that is slightly acidic to neutral, in a location that receives partial to full sun.

It thrives in cool to temperate climates and requires consistent moisture without waterlogging, making it suitable for regions with moderate rainfall or regular irrigation. Regular weeding and mulching help control weeds and retain soil moisture, while periodic fertilization with a balanced organic fertilizer supports healthy growth. Harvesting is best done in late spring to early summer when the roots are most mature, using a spade or trowel to carefully dig up the plants to avoid damaging the roots.

After harvesting, the roots should be washed, cut into pieces, and dried in a cool, well-ventilated area or using a dehydrator to preserve their potency, then stored in airtight containers in a cool, dark place to maintain their medicinal properties.
