Inoculating the Growing Medium with Shiitake Spawn
Now that we have prepared our growing medium, it’s time to inoculate it with shiitake spawn. This step is crucial in the shiitake mushroom growing process as it introduces the fungal spores that will eventually grow into mushrooms. There are different methods for inoculating depending on whether you’re using logs or sawdust blocks.
Inoculating Logs
If you’re growing shiitake mushrooms on logs, you’ll need to drill small holes into the logs and insert plug spawn. Plug spawn are small wooden dowels that contain the shiitake spores. Make sure to use a drill bit that matches the size of your plug spawn to create a snug fit.
Once you have drilled the holes, carefully insert the plug spawn into each hole, ensuring that they are tightly packed. To prevent any air or moisture intrusion, seal the holes with a food-grade wax. This wax acts as a barrier, protecting the spawn from contamination while allowing the mushrooms to grow.
Inoculating Sawdust Blocks
If you’re using sawdust blocks as your growing medium, the process of inoculation is slightly different. Firstly, you’ll need to break up the shiitake spawn into smaller pieces. This can be done by crumbling it with your hands or using a sterile utensil.
Next, mix the crumbled spawn evenly into the sawdust substrate. Be sure to distribute the spawn throughout the entire block to ensure uniform colonization. Once mixed, pack the sawdust spawn mixture tightly into a container or bag, ensuring it’s compacted but still breathable.
| Inoculating Logs | Inoculating Sawdust Blocks |
|---|---|
| – Drill small holes into logs | – Break up shiitake spawn |
| – Insert plug spawn into holes | – Mix spawn into sawdust substrate |
| – Seal holes with food-grade wax | – Pack sawdust spawn mixture tightly |
Remember, regardless of your chosen method, it’s important to maintain cleanliness and sterile conditions throughout the inoculation process. This will help prevent contamination and ensure a successful shiitake mushroom harvest.
Incubating and Fruiting Shiitake Mushrooms
Once the growing medium has been inoculated with shiitake spawn, it’s time for the incubation and fruiting stages.

Covering the logs with a breathable fabric, such as burlap or shade cloth, protects them from direct sunlight while allowing air circulation. This shade cover helps maintain consistent moisture levels and prevents the logs from drying out.
For sawdust blocks, they can be kept in grow bags or other containers that provide suitable ventilation. These containers should be placed in a shaded area as well.
2. Monitoring and Maintaining the Growing Environment
During the incubation and fruiting stages, regular monitoring of the growing environment is essential. Here are some key factors to consider:
- Temperature: Shiitake mushrooms thrive in temperatures between 60-75°F (15-24°C) during incubation and 55-65°F (13-18°C) during fruiting. Use a thermometer to monitor and maintain the desired temperature range.
- Humidity: Shiitake mushrooms prefer high humidity levels of around 80-90%. To maintain humidity, mist the logs or sawdust blocks regularly with water.
- Lighting: While shiitake mushrooms don’t require direct sunlight, they do need some light exposure. Ambient light or low-intensity artificial light can be sufficient for their growth.
3. Observing the Fruiting Stage
During the fruiting stage, the mushrooms will start to appear, indicating that they are ready for harvest. This is an exciting time as you see your efforts come to fruition.
Shiitake mushrooms typically take a few weeks to several months to start fruiting, depending on the growing method, environmental conditions, and specific mushroom strain. Keep an eye out for small, button-like mushrooms emerging from the logs or sawdust blocks.
As the mushrooms grow, they will undergo changes in color, shape, and size. Harvest the mushrooms when they reach their desired size and before the caps fully open. This ensures optimal flavor, texture, and overall quality.
Remember to harvest the mushrooms gently, using a sharp knife or scissors. Cut them close to the base, being careful not to damage neighboring mushrooms or the growing medium.
Harvesting and Maintaining Shiitake Mushrooms
Harvesting shiitake mushrooms at the right time is crucial to ensure the best flavor and texture. You should wait until the caps are fully formed but still closed before harvesting. This is usually when the caps are around 2-4 inches in diameter.
When harvesting, gently twist or cut the mushrooms at the base of the stem. Avoid pulling them forcefully, as this can damage the mycelium and impact future yields.
Once you’ve harvested your shiitake mushrooms, you can encourage the growth of new mushrooms by soaking the logs or sawdust blocks in water.
