Today, I pruned the Lemon Verbena, and harvested some Lemon Balm and Apple Mint. It's the simplest thing to put an elastic band around the stems and hang them upside down out of direct sun to dry. In about 3-4 days, I'll check them for dryness. Absolute dryness is a must, because any moisture in the herb will allow for mold to grow. The dried herb is put into an airtight jar in a dark, cool place, to store it for use anytime. I prefer to leave the leaves whole, as I think more of the essence is retained that way.
