For our sustainability project we have inoculated a variety of mushrooms in a few different types of substrates (substrates being the medium of which the mushrooms are grown on). We inoculated several oak logs that were cut down this past summer with shitake mushrooms, and one pine log with phoenix oyster. To do that our mentor Malaika ordered some plug spawn online (which are one inch dowels that have been colonized with mycelium. We then drilled holes in the logs, and plugged the holes with the dowels. After all the logs were plugged with the spawn, we covered the plugged holes and ends of the logs with beeswax to contain moisture. The logs should start fruiting anywhere between 6-18 months, and will continue to fruit for up to six years.
Since we love mushrooms and wanted to eat the ones we grow, we decided to grow some in bags also. Growing in bags doesn’t take as long to produce mushrooms. We did this by getting used coffee grounds from a café in Grass Valley, and saving the sawdust from when we drilled the oak logs. We inoculated pearl oyster mushrooms in coffee grounds, and shitake mushrooms in a mixture of coffee grounds and the sawdust. Unfortunately the mycelium is taking a while to spread throughout the bags, so we probably wont see them when they’re done growing.
Then, when preparing for the forest garden, a few trees were cut down. We decided to inoculate the stumps so mushrooms could be a part of the permaculture project. We had to girdle the stumps first to kill the tree because they have natural fungicides that can inhibit mushroom growth, and you have to wait until those fungicides go away. Then we drilled holes and inoculated the plug spawn. In the oak stump we inoculated more shitake, in the pine we inoculated turkey tail, in the honey locust we inoculated maitake (hen of the woods).
Having mushrooms grow here at Woolman will contribute to a more sustainable existence. Our kitchen will rely less on outside sources for mushrooms, and everyone here will benefit from their health benefits.
Here are some pictures of the logs, stumps, and bags we inoculated.







I would love to see the photos! I didn't see them on the blog site.
This is a very exciting project. I am supposed to be incorporating these healthy mushrooms in my own diet, and have wondered how to go about growing them! I liked this article and found it inspiring.
