Growing, Harvesting and Storage

Teucrium marum grows in well-drained, loamy soil with a slightly acidic to neutral pH, thriving in full sun to partial shade, and requiring moderate moisture without waterlogging.

It prefers temperate climates and can be planted in early spring or fall, with consistent watering during its establishment phase. Regular weeding and pruning of dead foliage help maintain its vigor, while mulching around the base can retain soil moisture and suppress weeds. The best time to harvest teucrium marum is during the summer months, when the leaves are most aromatic, using clean scissors to cut the top 10-15 cm of the plant to encourage regrowth.

For optimal potency, the harvested plant should be dried in a shaded, well-ventilated area, then stored in airtight containers in a cool, dark place, or refrigerated in sealed bags to preserve its medicinal properties.
