About Oregano

Oregano is heat-loving drought-tolerant and more flavorful when stressed — poor soil actually produces more aromatic leaves.

Plant in full sun well-drained soil. Harvest before flowering for best flavour. Cut to the ground once or twice a season to encourage fresh growth. Dry or freeze for winter use.
