drying-herbs-56 How to Preserve Herbs – Drying Herbs Drying herbs is pretty self explanatory, but the most space intensive way to preserve herbs. If you choose this route, you must have a warm, dry indoor area to hang the herbs. Hang them in small bunches, cover them to keep them clean, and when dry, strip the leaves off the branches and seal in bags or jars. Make sure they are crispy dry before you seal them up. You can also dry herbs in the microwave or a food dehydrator.
