How to grow Shiitake

The shiitake can be grown outside or inside using logs that have kept its bark and retains it for several years.  Shiitake grown outside needs plenty of shade and protection from the wind but can be grown in large numbers with minimal space.  To grow shiitake mushrooms you must first buy what is called “mushroom plugs”, which are dowels of wood that contain the mushroom mycelium.  You place these plugs into drilled holes of a fresh cut log; the best logs to use are alder tree but other types of hardwood trees can be used as well; oak is said to work very well.  The drilled holes should be approximately four inches apart.  The plugs are put into the holes until they are flush with the log making sure not to damage the bark of the log.  Using melted cheese wax, seal the plugs using a brush to protect against insects or other types of fungi.  The logs are then placed in shaded areas; the logs should be stood up and not laid down.  The logs should be watered every two weeks, preferably with chlorine free water; rain or well water is best.  The mushrooms take from six months to a year to appear and one log will last up to four years.
