Shiitake mushrooms are loved for their rich flavor and numerous health benefits. For home growers, growing shiitake mushrooms provides a satisfying experience provided the proper fruiting conditions are created. In this blog post, we will discuss the essential steps and environmental conditions required to successfully grow shiitake mushrooms.
Where do shiitake grow?
Shiitake mushrooms grow naturally on hardwood trees such as oak, beech, chestnut and walnut. These mushrooms are native to East Asia, where they have been grown and consumed for centuries. Today, shiitake mushrooms can be grown indoors or outdoors, depending on available space and resources.
Indoor Growing
A controlled environment is essential for growing shiitake mushrooms indoors. Here are the steps:
- Substrate Preparation: Use a mix of sterilized wood chips and wheat bran, impregnated with shiitake mycelium.
- Ideal Conditions: Maintain a temperature of 15-20°C and a humidity of 80-90%. Ensure good ventilation.
- Steps:
- Sterilize the substrate and allow it to cool to room temperature.
- Inoculate the substrate with shiitake mycelium and mix well.
- Place the substrate in bags or containers and seal them.
- Store in a dark place at 15-20°C.
- Keep the substrate moist by spraying with water.
- Wait until the mycelium has colonized the substrate and the mushrooms appear.
Outdoor Growing
The following steps are important for outdoor cultivation:
- Timing: Plant preferably in late spring or early summer.
- Wood selection: Use hardwood such as oak or beech.
- Steps:
- Cut wood into blocks or logs (10-15 cm thick).
- Drill holes in the wood and fill them with shiitake spawn.
- Seal the holes with beeswax or another protective substance.
- Place the logs in a shady area with good air circulation.
- Keep the trunks moist by spraying with water.
- Wait several months to a year for the mushrooms to grow.
Is shiitake a mushroom?
Yes, shiitake is a mushroom. It is an edible mushroom known for its rich, umami flavor and numerous health benefits. Shiitake mushrooms contain many nutrients, including B vitamins, vitamin D, and minerals such as zinc and selenium. They are often used in Asian cuisine and are popular in soups, stir-fries and as a meat substitute.
How much shiitake can you eat?
The recommended amount of shiitake mushrooms you can eat varies depending on your diet and health condition. In general, it is recommended to consume no more than 100 grams of fresh shiitake mushrooms per day. For dried shiitake this is about 10 grams per day. It is important to remember that shiitake mushrooms, like other foods, should be consumed in moderation to avoid possible side effects.
What does shiitake do to your body?
Shiitake mushrooms have several health benefits:
- Immune boosting: Shiitake contains polysaccharides such as lentinan, which can strengthen the immune system.
- Anti-inflammatory: The mushrooms have anti-inflammatory properties that can help reduce inflammation in the body.
- Cholesterol lowering: Shiitake can help lower cholesterol levels thanks to the presence of eritadenine.
- Antioxidants: They contain antioxidants that help fight free radicals and reduce oxidative stress.
Steps for Creating Fruiting Conditions
Select Suitable Logs or Tree Trunks
Use hardwood trunks such as oak, beech, chestnut or walnut. The logs should be freshly cut, preferably within the last few weeks, to maintain adequate moisture. Let the trunks rest for 2 months to deactivate their natural defenses against mold.
Inoculate the Tribes
Drill holes in the trunks, approximately 20 holes spread over 5 rows, with a minimum distance of 8 cm between each hole. Place shiitake spawn (dowel spawn) in the holes, making sure the spawn fits securely in the holes. Seal the holes with wax to protect the spawn and retain moisture.
Environmental conditions
- Temperature: Shiitakes grow best at temperatures above 7°C at night and above 15°C during the day.
- Humidity: Keep the trunk moist, especially during dry periods. Preferably use rainwater.
- Location: Place the trunk in a shady, moist area where it can receive natural rainfall.
Incubation period
The mycelium will colonize the trunk for about a year. Avoid extreme temperatures during this period.
Fruiting Initiate
After a year, you can induce fruiting by soaking the stem in cold water to "shock" the mycelium. This can speed up the fruiting process, leading to mushroom growth within two weeks. Make sure the trunk is kept in a frost-free environment during this process.
Harvest
Harvest shiitakes when the edges of the caps begin to curl. Cut the stems at the base close to the trunk. Clean the mushrooms with a damp cloth to remove dirt.
Materials Needed
- Trunk: Preferably oak or other suitable hardwood.
- Drill: To make holes for the spawn.
- Shiitake Spawn (Deuvelbrood): Available from specialist suppliers.
- Water source: For maintaining moisture and soaking the trunk.
Important Environmental Conditions
- Temperature: Above 7°C at night and 15°C during the day.
- Humidity: Consistently humid environment, supplemented with rainwater as necessary.
- Shady Environment: To avoid direct sunlight and maintain humidity.
Alternative Growing Methods
- Grow Kits: For a simpler approach, grow kits containing beech sawdust blocks inoculated with shiitake spores can be used. These kits require less preparation and can be placed indoors.
- Pre-infected Strains: These stems have already been inoculated and can be placed directly in the garden or on the balcony. They require similar care as described above.
By following these steps and maintaining proper environmental conditions, you can successfully create fruiting conditions for shiitake mushrooms and enjoy a bountiful harvest.
