Shiitake Mushroom Logs

Source: The Martha Stewart Show, November 2010


Each log will produce about 2 to 3 pounds of mushrooms.


  • Healthy white oak log, approximately 6 inches in diameter and 4 to 5 feet long at the most

  • Drill with 5/16-inch drill bit

  • Rubber mallet

  • Wood dowels, inoculated with shiitake mycelium

  • Wax for melting

  • Mini Crock-Pot

  • Small paintbrush


  1. Drill several 1-inch-deep holes, about 4 inches apart, into surface of log using a 5/16-inch drill bit.

  2. Using a rubber mallet, hammer wood dowels that have been inoculated with shiitake mycelium (the living body mass of the fungus) into the holes. The mycelium will enter the log and spread throughout the wood.

  3. Melt wax in Crock-Pot. Using a small paintbrush, cover each hole with melted wax.

  4. Place log in well-shaded place, like the north side of a shed or underneath a porch. Water regularly, keeping log wet. Mushrooms should bloom in approximately six months, and the log should continue to produce mushrooms every six months for about six years.
