Hi Jerry:
You can purchase bareroot nursery stock from a private nursery (Forrest Keeling, Midwest Seedling Supply, Hensler Nursery, Woody Warehouse Nursery, etc.). Check out their websites via your preferred browser and search engine.
Alternatively, you may purchase bareroot nursery stock from the IL Dept. of Natural Resources by contacting your local IDNR district forester:
