Growing, Harvesting and Storage

Pseudostellaria heterophylla grows best in well-drained, loamy soil with a slightly acidic to neutral pH, in full sun to partial shade, and requires consistent moisture without waterlogging.

It thrives in temperate climates and should be planted in early spring after the last frost, with spacing of about 30 cm between plants to allow for adequate air circulation. Regular weeding and mulching help control weeds and retain soil moisture, while occasional fertilization with a balanced organic fertilizer supports healthy growth. Harvesting is best done in late summer to early autumn when the plant has matured, using scissors or a sharp knife to cut the entire plant at the base, ensuring minimal damage to the roots.

After harvesting, the plant should be thoroughly dried in a cool, shaded area with good airflow to preserve its medicinal potency, then stored in airtight containers in a cool, dark place or refrigerated to maintain its therapeutic properties.
