Blue Oyster Mushroom
Blue oyster mushrooms are edible fungi that belong to the genus Pleurotus Ostreatus.
Oyster mushrooms get their name from their appearance, similar to that of an oyster, and grow on hardwoods, logs, stumps, and cardboard.
Blue oyster mushrooms are known for their medicinal properties (vitamins and minerals) and are often used in traditional Chinese Medicine.
Blue oyster mushrooms are one of the subspecies of the oyster mushroom family. They are a good source of antioxidants and vitamins, making them a healthy addition to any diet.
This humble fungus has a lot to offer: it’s easy to grow, nutritious, & delicious. With so many advantages, they are popular among vegans and vegetarians as a meat substitute.
Blue Oyster Mushroom’s Appearance:
Blue oyster mushrooms are small & shelf-stable with a powdery blue-gray or deep blue exterior. Once cooked, they have a creamy white interior with a slightly crunchy texture.
They grow as clusters of different sizes and shapes on hardwood trees. Blue oyster mushrooms are native to North and South America but can be found in temperate climates worldwide.
Blue oyster mushrooms are super easy to grow at home, making them perfect for beginners.
All you need is a little patience (it takes about two weeks for them to fully mature) and some basic supplies like a growing kit & some organic matter to act as substrate (coffee grounds work great).
Once you’ve got your spawn (mushroom spores), the hardest part is over.
Just keep an eye on humidity levels and ensure your substrate doesn’t dry out – other than that, these little guys take care of themselves.
When and Where to Grow:
You can grow them year-round, indoors or outdoors. If you live in a cold climate, you might want to consider moving your operation indoors, where temperature & humidity levels are easier to control.
Outdoors, all you need is a shady spot with good airflow. A north-facing porch or balcony would be ideal.
Indoors, any room in your house will do as long as you can provide 12 hours of indirect light per day (a sunny windowsill works perfectly).
In a study done by the University of California, blue oyster mushrooms have the potential to yield 227% more than white button mushrooms.
This is due to the fact that they are able to produce two flushes of fruit body compared to the one flush produced by white button mushrooms.
In terms of fresh weight, this means that blue oyster mushrooms can yield up to 9 pounds per square foot while white button mushrooms can only yield up to 4 pounds per square foot.
Raw oyster mushrooms will last about one week in the fridge with proper storage conditions.

Fruiting is when the mushrooms produce fruit bodies, the parts of the mushroom that we can see above ground.
This process is important because it allows the mushroom to reproduce and continue its life cycle.
Oyster mushrooms typically fruit in the late fall and early spring, although they may fruit sporadically throughout the year.
The best time to harvest is when the caps are 6-8 inches in diameter, and the margins are still curled inward. It’s best to eat them when fresh.
