Harvest Tips
Begin light harvesting once plant is established (4-6 weeks from planting); pinch off top 1-2 inches of stems to encourage bushiness; harvest in morning after dew dries for best flavor and aroma; can be harvested continuously throughout growing season; dry leaves by hanging in bundles or dehydrating at low temperature (95-105°F); fresh leaves have strongest flavor
