What You'll Learn
Shiitake mushrooms are grown on oak logs
Shiitake mushrooms are one of the most common edible mushrooms in the world. They are highly valued as food and as a health tonic in the Far East, where their cultivation began over a thousand years ago. The earliest accounts of shiitake mushroom cultivation date back to the 1200s in what is now Southern Japan. The earliest methods of farming involved dragging fallen boughs of a native evergreen tree related to oaks and beech trees, called a shii, that had been found with sprouting shiitake mushrooms into the courtyards. The word shiitake is a combination of the word shii, meaning a type of tree, and the Japanese word take, meaning mushroom.
Today, shiitake mushrooms are still grown on oak logs in a natural forest habitat. Logs are cut in the fall at about eight inches in diameter. They are then inoculated with spores, which are inserted into drilled holes. The logs are then placed outdoors in a shady location to incubate until they are ready to fruit. The logs should be inoculated within a few weeks of cutting to prevent the log from drying out or other fungi from growing.
Oak logs are ideal for growing shiitake mushrooms because they are dense hardwoods, which take longer to fully colonize but will continue to produce mushrooms for more years. On average, a mushroom log will produce mushrooms for one year per inch of diameter, so a five-inch diameter oak log will likely produce mushrooms for five years. Logs can be left to rest for 8-10 weeks after harvesting and can be re-soaked to produce another flush of mushrooms.
Shiitake mushrooms are a good option for growing on logs because they are extremely easy to grow and will produce multiple years' worth of gourmet mushrooms without needing to re-inoculate the logs.
