Have you ever thought about growing your own shiitake mushrooms? It's a fascinating and rewarding hobby that not only produces delicious mushrooms, but also offers a deeper connection with nature. Whether you are a seasoned gardener or a complete beginner, growing shiitake mushrooms can be an enriching experience. In this blog post, we will discuss the essentials and steps to successfully grow shiitake mushrooms, both indoors and outdoors.
What do you need to grow mushrooms?
Substrate
The substrate is the material on which the mushrooms grow. For shiitake mushrooms, there are two main options: wood chips and hardwood logs.
- Wood chips: Often beech wood flour, mixed with wheat bran for extra nutrients.
- Hardwood logs: Oak, beech, chestnut or walnut are ideal for shiitake growing.
Mycelium (Brood)
Shiitake mycelium, also called brood, is the fungus that produces the mushrooms. This is available from specialist suppliers and is essential for starting your grow.
Sterilization equipment
To prevent unwanted microorganisms from contaminating your culture, sterilization of the substrate is crucial. This can be done with:
- An autoclave or pressure cooker for steam sterilization.
- An oven for heat treatment.
- Chemical sterilization with hydrogen peroxide or bleach (optional).
Tools
To inoculate the wood or substrate you need the following:
- A drill (e.g. 9 mm) for making holes in trunks.
- Wax (beeswax) for sealing inoculation points.
- Containers or bags for the substrate.
Environment
Shiitake mushrooms require specific environmental conditions to grow:
- A dark, moist area for incubation.
- Controlled temperature and humidity settings.
How do you grow shiitake?
Indoor cultivation
- Preparation of the Substrate:
- Mix wood chips and wheat bran in a 1:1 ratio.
- Sterilize the mixture and let it cool to room temperature.
- Inoculation:
- Add shiitake mycelium to the substrate and mix well.
- Place the substrate in bags or containers and seal them.
- Incubation:
- Store in a dark place at 15-20°C.
- Keep the humidity at 80-90% by regularly spraying with water.
- Fruiting:
- After several weeks to months, the substrate will be completely colonized and shiitake mushrooms will appear.
Outdoor cultivation
- Selection of Wood:
- Use hardwood such as oak or beech.
- Cut the wood into blocks or logs (10-15 cm thick).
- Inoculation:
- Drill holes in the wood and fill them with shiitake spawn.
- Seal the holes with beeswax or another protective substance.
- Placement:
- Place the logs in a shady area with good air circulation.
- Keep the trunks moist by regularly spraying with water.
- Fruiting:
- Shiitake mushrooms will begin to grow after several months to a year.
Which wood for shiitake?
Choosing the right wood is crucial for successful shiitake cultivation. Hardwoods such as oak, beech, chestnut and walnut are ideal because they provide the right nutrients and structure for the mycelium to grow. Avoid softwoods such as pine or spruce, as these do not provide the right environment for shiitake mushrooms.

Harvesting and Storing Shiitake
Harvest
Harvest your shiitake mushrooms when the caps have opened but before the edges curl up. Carefully loosen the mushrooms or use a knife if necessary to avoid damaging the substrate.
Save
Fresh shiitake mushrooms can be stored in the refrigerator for several days. For longer storage they can be dried, frozen or preserved.
Additional Tips for Successful Shiitake Growing
- Choose the right wood: Use untreated hardwood such as oak or beech.
- Prepare the substrate properly: Sterilize the substrate to minimize competition from other microorganisms.
- Maintain optimal conditions: Provide proper temperature, humidity and ventilation.
- Harvest carefully: Harvest at the right time and handle the mushrooms carefully to avoid damage.
By following these steps and using the necessary materials, you can successfully grow shiitake mushrooms both indoors and outdoors. Good luck and enjoy your homegrown shiitake mushrooms!
