Ideal Environment Ideal Environment

You can grow Shiitake mushrooms in a grow bag (saw dust usually) or on oak logs.  If treated correctly and placed in the right environment, it is said that logs can last for up to 5 years and fruit 3 times a year.  It takes a year or so before they start fruiting, but it is worth the wait if you have a shady spot in your garden.  The ideal temperature for them is somewhere around 8 to 23 degrees Celsius.

Cut the logs during the winter and inoculate them  in the spring.  Remember the bark should be in tact. Make sure the logs are stored in a shady spot (no direct sunlight), under some trees or between ferns, even under some garden sheet covering or behind a shed.  You can place several logs on-top of each other to create a structure that will not take up too much space and you can place them partially in the soil so that there is enough moisture.

How to Plant How to Plant

Purchase pre-made dowels (wooden plugs) from an online shop that already has the mycelium (the white stuff) growing on it, or buy you own plugs, spores etc. and make your own.  Drill a hole about as big as the dowel and insert the dowel, hammer it down till it is level with the surface and seal with a little bit of heated wax.  Repeat this for each hole, make about 12 to 18 per log, depending on the size, at least every 30 cm.

How to Water How to Water

The logs should never dry out completely, but it they are ontop of the ground or some are, then it should be fine.  During the winter you can cover it with some leaves, a cover or even snow is fine.  During the harvest time you can shock the logs every 8 weeks to encourage fruiting, and you can keep the logs moist if you live in a drier area (if no rain, hose the logs down once every other week).

Companion Planting Companion Planting

Oak logs with shiitake mushrooms growing on them make an excellent feature in a garden.  Place them under trees, between trees or fill some lost space in the garden that is nice and shady.  In general mushrooms make fantastic companion plants, usually oyster or white mushrooms are the best.  Mushrooms that grow on the roots of plants help them take up additional nutrients. 

How to Propagate How to Propagate

Shiitake mushrooms can be grown from spores (buying or collecting) or by cloning the mushrooms, by simply taking bits and placing it on the substrate.  Remember that you should work as clean as possible to avoid contamination, sterilise what you can.  After a couple of weeks you will start seeing the mycelium (white network growth).

How to Harvest How to Harvest

Usually from May to November (around 18-20 degrees Celcius is good).  To encourage fruiting you can wet the logs and give it a good bump against the ground (shocking it), once every 8 weeks only.  Harvest mushrooms when they are open, well rounded with open gills underneath.  Pick them by gently twisting base or cutting them off, take care not to harm the mycelium.
