Ginseng is a perennial plant that grows up to 2' when mature.

Preparing your Ginseng for Market
Ginseng roots must be washed by rubbing gently with your finger tips in clean water. Roots should be layed on a screen and dried with proper air circulation, drying slowly out of direct sunlight. When the roots are thoroughly dried, store them in a paper sack, so that they will not mold. Make sure stored roots are not subject to high humidity. Be careful not to break the roots, and leave the dried neck (the part of the previous years stem)in tact.

Finding A Market for Herbs
There are only a few large ginseng buyers left in the United States. Small buyers are becoming less available. If you cannot find other buyers on the internet, you can call the Ohio Department of Natural Resources and they may have a list of dealers.
