Growing Tips

Harvest roots in the second autumn when valerenic acid content peaks; wash, slice, and dry at max 40C to preserve active compounds.

Remove flower stalks in the first year to direct energy to root development — flowering reduces root mass significantly.

Prefers cool, moist conditions; in warm climates, grow in partial shade with consistent irrigation.
