Blue Oyster Mushroom Cultivation
Pleurotus ostreatus: A fast substrate colonizer with a strong blue / grey hue.
Blue Oyster Spawn comes in three distinct styles.
Plug Spawn- great for first time mushroom log growers. Used for small projects. 1-10 logs
Sawdust Spawn- used for larger mushroom log projects, or by those wanting to inoculate logs every year. Used for small to large enthusiast or commercial projects. Best for inoculating 10 or more logs. *You need an Inoculation Tool to use Sawdust Spawn! For larger projects you may want to purchase an Angle Grinder Adapter and specialized 12mm drill bit!
Grain Spawn- this is used for outdoor straw or wood chip beds or commercial indoor production using sawdust or straw. You do not use Grain Spawn for log inoculation.
On logs - Blue Oyster works well with the Log, Stump, and Totem methods. Colonization is fast and may start producing in 4-12 months, though fruitation is dependent on environmental triggers. They fruit best in the Spring and Fall and prefer softer hardwoods such as Poplar and Birch. Though they will also work on Maple or Oak.
Outdoor beds - With oyster mushrooms you may also choose to use grain spawn to inoculate outdoor straw beds. We've had success growing blue oyster mushrooms in our raised garden beds by sprinkling grain spawn in the beds in the spring. We had blue oysters growing right out of our soil!
Difficulty: 2 of 10 Oyster mushrooms are a great mushroom for beginners. They colonize quickly and are reliable producers. Great for commercial cultivation, especially grown on straw.
Cooking: Blue Oysters can easily replace button mushrooms in most recipes and pair well with many cuisines and flavors. Like all Oyster Mushrooms, they retain water and develop a slimy texture when cooked. If you prefer a firm texture, continue to cook Oysters until crisp.
Properties: The Blue Oyster Mushroom has a high protein content, several B vitamins, and all the essential amino acids (Marley, 2009). Its medicinal benefits include promoting anti-tumor activity and lowering high cholesterol. Oyster Mushroom fruiting bodies and distillations have been shown to reduce tumor size in several studies on mice, rats, and hamsters (Hobbs, 1995). Additionally, Oyster Mushrooms have been used in the Czech Republic as the main ingredient in a dietary supplement used to treat high cholesterol (Hobbs, 1995). Studies in animals have shown that a diet of Oyster Mushrooms reduced the development of plaque in major arteries (Bobek et al., 1995).
