Shimeji mushrooms or beech mushrooms are quite easy to grow, and they grow all year round. However, their original variety, considered a delicacy in Japan, is a little high maintenance. In this article, we will cover both the simple method and the professional method to grow brown beech mushrooms.

Materials Required

  • A beech tree or any hardwood tree, like hazelnut, oak, or willow, if you are opting for growing them in the wild on tree logs.
  • Substrate (growing medium)
  • Pots or containers
  • Dried beech mushrooms
  • Plastic wrap
  • Aluminium foil
  • Water

Step-by-Step Instructions

  1. Take a suitable-sized container to grow your brown beech mushrooms. You can also use an aquarium or a terrarium for the cultivation process.
  2. Once the container is chosen, it is time to prepare the substrate. You can either prepare your substrate, act as the growing medium or buy it online.
  3. Use dead leaves and plants, sawdust, and similar things to create the substrate. Before adding it into the container, be sure to cook the substrate to kill all insects and spores.
  4. Take your substrate and start filling in your container. Fill the container until it is three-quarters full. Use a blunt end stick or a broomstick to shove the substrate firmly. The substrate should be very firm and tightly packed.
  5. Add a thin layer of about 0.5 to 1 cm of dried brown beech mushrooms over the substrate layer, and then cover it again with a 1 cm thick substrate layer on top.
  6. Spray water on the substrate to make it gently moist.
  7. Now cover the top of the container with a plastic wrap. It will help retain the moisture and heat inside the container, essential for germination.
  8. Put a layer of aluminium foil over the plastic wrap and wrap it tightly over the edges of the container.
  9. Now cut a piece of cardboard and tape it over the aluminium foil.
  10. Place your mushroom container in a dark, humid spot. Maintain a warm temperature of about 25 to 28 degrees Celsius. Maintain these conditions for 4 to 12 weeks until you see tiny white dots called mycelia growing on the substrate.
  11. Remove the cardboard and plastic cover to water the substrate top 2 to 3 times every week.
  12. Place an aquarium with bright light or a simple lamp two to three feet away from the mushrooms to provide them with enough light to grow. After some weeks, the mycelia will start growing fruiting bodies of mushrooms.
  13. If tiny white mushrooms appear at the surface of the substrate, then remove them as they are still white-colored.
  14. Add a layer of leaves on top of the substrate, so the fruiting bodies have something to grow on.
  15. You will know when the mushrooms are ready by checking their color. They are ready to be harvested once the color turns brown or brownish-black from white. At this point, they would be quite dried out from the bases. Just twist and turn until your mushrooms come loose from the substrate.
