Growing, Harvesting and Storage

Lythrum salicaria grows in moist, well-drained soil in full sun to partial shade, thriving in areas with consistent moisture such as wet meadows, stream banks, and marshy fields. It prefers loamy or sandy soils with a slightly acidic to neutral pH and requires regular watering to maintain its lush growth. To ensure healthy development, it should be planted in early spring, and mulching helps retain soil moisture and suppress weeds.

After harvesting, the plant material should be dried in a cool, shaded area with good air circulation, then stored in airtight containers in a cool, dark place to preserve its medicinal potency.
