Marty, first of all, clean the roots as soon as you dug but do not scrub. A little soil left around the root rings may enhance its value.
Spread cleaned roots on a piece of old ply wood or screen rack in the shade for drying. Don?t put them directly in the sun to dry. The sun will discolor the roots to some degree. Turn them frequently and provide adequate aeration. Drying time varies with root size and drying techniques. Large roots require three or more weeks to dry at room temperature or outdoors but small roots dry in a few days. I dry them until they just start to snap when you bend enough to break them. Do not oven dry or put them in the microwave. Drying too fast will discolor the roots. Store the dried roots in a dry, airy, rodent-proof place until ready for sale. Hope this helps.
