The process begins with logs that are 4 to 8 inches in diameter. We drilled holes in a diamond pattern 4 to 5 inches apart in rows 1 to 2 inches apart all the way around the log. Next, we hammered in the wooden plugs that are covered in the blue oyster mushroom spawn (Pleurotus columbinus). Then we sealed each hole with wax to keep the good fungus in and the bad fungus out. For now, we’ll keep the logs stacked in a shady spot and water them to keep them moist.
Over the course of the next few months, the mycelium will start growing inside the log connecting together in a giant web. Mycelium, by the way, is the white, stringy material you see when you pull up bark on a decaying log in the woods. The mycelium will grow and grow until it’s ready to fruit and send out its spores—that’s when we’ll see mushrooms! For the blue oyster mushrooms that could be as early as this fall, but could take up to a year.
