Growing, Harvesting and Storage
Pueraria lobata grows best in well-drained, loamy soil that is rich in organic matter, with a pH ranging from 6.
0 to 7. 5, and thrives in full sun to partial shade. It requires consistent moisture, especially during its growing season, but should not be overwatered to avoid root rot. Regular weeding and occasional fertilization with a balanced fertilizer can promote healthy growth and maximize medicinal compound production. Harvesting should occur in late summer to early autumn when the plant's active constituents are most concentrated, using a sharp knife to cut the stems and leaves carefully to avoid damaging the plant.
For storage, the harvested material should be dried in a cool, well-ventilated area away from direct sunlight, then stored in airtight containers in a cool, dark place or refrigerated to preserve its potency and extend shelf life.
