Growing, Harvesting and Storage

Scolopendrium vulgare grows in well-drained, acidic soils in full sun to partial shade, preferring moist but not waterlogged conditions, often found in rocky or woodland areas.

It thrives in temperate climates with cool winters and mild summers, and requires regular watering during dry periods to maintain soil moisture. To ensure healthy growth, it should be planted in a location with good air circulation to prevent fungal diseases, and mulching can help retain soil moisture and suppress weeds. Harvesting is best done in late summer to early autumn when the plant's medicinal compounds are most concentrated, using clean, sharp tools to cut the stems and leaves without damaging the plant.

For optimal potency, the harvested material should be dried in a cool, dark, well-ventilated area, then stored in airtight containers away from light and moisture, ideally in a refrigerator to preserve its active compounds.
