Agreat way to grow mushrooms outdoors is on logs. If you take care in starting them off, they can produce mushrooms periodically for up to 10 years.There is growing variety in the mushrooms available too, not only shiitake and oyster, but also lion’s mane and even chicken of the woods. Even if you can find these for sale in the shops they are expensive, and mushroom logs really pay off in terms of effort and cost versus the financial and nutritional value of the produce.
