Most people who grow herbs find some occasion to dry them, and there are a number of techniques that works well. Your ultimate goal is for the herb to dry out without any trace of moisture, mold, or mildew. You also want to maximize flavor retention. Most dried herbs gain potency while a few others lose it. You will also discover that “fresh” dried herbs beat out their packaged, store-bought cousins in terms of taste, intensity, and aroma.
