Termite mushrooms, a natural delicacy, are highly sought after for their unique aroma, delicious flavor, and nutritional value. While foraging for wild termite mushrooms used to be challenging due to limited availability, modern cultivation techniques now allow you to grow black termite mushrooms at home. Join Nongnghiepvietnam.org as we explore the secrets to successful black termite mushroom cultivation.
Can Termite Mushrooms Be Cultivated?
There are two common types of termite mushrooms: white and black. While white termite mushrooms only grow in the wild in limited quantities and have no established cultivation methods, black termite mushrooms can be grown on sawdust substrates. This makes black termite mushrooms an ideal choice for those who love the distinctive flavor of termite mushrooms without worrying about scarcity or high prices. Black termite mushrooms offer a similar crunchy texture, rich aroma, and firm consistency to their white counterparts, promising a delightful culinary experience.

How to Grow Black Termite Mushrooms
To successfully cultivate black termite mushrooms, you need to master the technical steps from sawdust preparation to harvesting.
1. Sawdust Preparation
Sawdust is a crucial component in black termite mushroom cultivation, directly impacting yield and quality.
1.1. Sawdust Selection
- Choose sawdust: Prioritize sawdust from bodhi and rubber trees. Avoid sawdust from hardwood or trees containing essential oils.
- Store sawdust: Dry the sawdust thoroughly and store it in a cool, dry, and well-ventilated area for later use.
1.2. Moisturizing the Sawdust
- Sprinkle clean water onto the sawdust pile and mix thoroughly by hand.
- Check moisture level: Squeeze a handful of sawdust. If water slightly seeps out between your fingers, the moisture level is appropriate.
- Cover the sawdust with a nylon sheet for a few days.
- Mix the sawdust with lime powder at a ratio of 0.5 kg of lime powder per 100 kg of sawdust.
- Check the moisture content using a specialized device, ensuring it reaches 65%.
- Continue incubating the sawdust for 4-6 days, turning it 2-3 times per day.

1.3. Bagging the Sawdust
- Fill bags with sawdust, compacting each layer until the sawdust is 5-7cm below the bag opening.
- Securely tie the bag opening with a rubber band.
- Roll a piece of non-absorbent cotton and attach it to the bag’s neck before sealing the bag with a lid.
2. Sterilizing the Sawdust Bags
Sterilization is crucial to eliminate harmful bacteria and mold, ensuring an ideal environment for black termite mushroom growth. There are two common sterilization methods:
2.1. Method 1: Steaming
- Use a drum to steam the sawdust bags for 10-12 hours.
- Ensure the temperature inside the sawdust bags reaches 95-100 degrees Celsius.
2.2. Method 2: Pressure Cooking
- Steam the sawdust bags in an industrial pressure cooker at 120-180 degrees Celsius for 120-125 minutes.

Note: For large-scale cultivation, you can build a saturated steam oven for 9-10 hours to save time.
3. Black Termite Mushroom Cultivation Techniques
After the sawdust bags have cooled, you can proceed with mushroom spawn inoculation. There are two common inoculation methods:
3.1. Using Grain Spawn
- Use a metal rod to take a small amount of grain spawn (mushroom mycelium) and sprinkle it evenly over the surface of the sawdust bag.
- The inoculation rate should be approximately 1.2% of the sawdust bag’s weight.
3.2. Using Dowel Spawn
- Use sterilized forceps to pick up a dowel spawn and insert it into the planting holes on the sawdust bag.
- Insert one dowel spawn per hole, with the end of the dowel close to the surface of the sawdust.
4. Fruiting Body Formation
After inoculation, incubate the mushroom bags in a dark, well-ventilated room with high humidity. Once the mycelium has fully colonized the sawdust bag, you can induce fruiting body formation using two methods:
4.1. Fruiting in Grow Bags
- Place the mushroom bags close together and open the bag openings.
- Cover the top with a 2.5-3cm layer of soil.
4.2. Growing in Raised Beds
- Remove the nylon bags and arrange the mushroom blocks close together on the ground.
- Cover the top with a 2.5-3cm layer of soil mixed with lightweight powder and rice husk.

Note: The inoculation room should be airtight, all tools must be sterilized, and inoculation should be performed under the light of an alcohol lamp.
Termite Mushroom Care and Harvesting
1. Mushroom Care
- Maintain stable soil moisture: Avoid excessively dry or wet soil during the first 20-30 days.
- Watering: Once fruiting bodies form, gently water with a mist sprayer 2-3 times per day.
- Gradually reduce watering to maintain 95-98% humidity and a temperature of 24-32 degrees Celsius for optimal fruiting body development.
2. Harvesting
- Harvest when mushrooms reach the following size: Stem length 10-15cm, stem diameter 1.5-2cm, mushroom cap 3-5cm.
- Ideal harvest time: Early morning or late afternoon.
- Harvesting method: Harvest the entire mushroom, including the base.
- Harvesting duration: After the first harvest, subsequent harvests can occur every 2-4 days, lasting approximately 16 days per cycle.
Delicious Termite Mushroom Dishes
Harvested black termite mushrooms can be prepared into various delicious and nutritious dishes for your family, such as:
- Braised termite mushrooms with black pepper
- Termite mushroom porridge
- Stir-fried termite mushrooms with beef
- Termite mushroom pancakes
