Growing Tips
Flavor intensity is greatest in dry, nutrient-poor soils; excessive fertilization produces lush growth but dilutes essential oil content.
Harvest at full bloom for maximum carvacrol content; dry rapidly in shade to preserve color and aroma.
Propagate from cuttings or division for reliable flavor profiles; seed-grown oregano is highly variable in oil composition.
