Growing Shiitake Mushrooms: A Comprehensive Guide for Beginners
Introduction
Shiitake mushrooms are a highly prized delicacy in Japan, where they’re widely used in cooking. Until recently, most shiitakes consumed in the United States were imported from Japan. However, with increasing demand, shiitake mushroom cultivation has become a viable and profitable enterprise in the U.S.
Growing Shiitake Mushrooms at Home
Growing shiitake mushrooms at home is not as difficult as you might think. They’re wood-decay fungi, meaning they grow on logs. You can grow them either on logs or in bags of nutrient-enriched sawdust, known as bag culture.
Choosing the Right Logs
If you choose to grow shiitakes on logs, it’s important to select the right type of wood. Shiitakes prefer oak, but they can also grow on maple, birch, poplar, aspen, beech, and several other species. Avoid using live or green wood, deadfall wood, or logs with lichen or other fungi.
Preparing the Logs
Once you have your logs, you need to season them for about three weeks. This means leaning them against each other in a shaded area to dry out. If you leave them on the ground, they may become contaminated with other fungi or pests.
Inoculating the Logs
After the logs have seasoned, it’s time to inoculate them with mushroom spawn. Spawn is the mycelium of the shiitake mushroom, which is essentially the “seed” that will grow into mushrooms. You can purchase spawn from online suppliers in either dowel or sawdust form.
To inoculate the logs, drill holes every 6 to 8 inches around the log and 2 inches from either end. Plug the holes with either the dowels or sawdust spawn. Then, melt some beeswax in an old pot and paint it over the holes to protect the spawn from contamination.
Storing the Logs
Stack the inoculated logs against a fence, tepee style, or lay them on a bed of straw in a damp, shaded area. That’s it! Your logs are now ready to grow shiitake mushrooms.
Harvesting Shiitake Mushrooms
Mushrooms should appear sometime between 6 and 12 months after inoculation, usually after a day of rain in the spring, summer, or fall. Shiitake logs will continue to produce mushrooms for up to eight years, so they’re a great investment for your garden.
Tips for Growing Shiitake Mushrooms
- Water the logs heavily or submerge them in water if you don’t get enough rainfall.
- Keep the logs in a shaded area with good air circulation.
- Avoid overwatering the logs, as this can lead to rot.
- Be patient! Growing shiitake mushrooms takes time, but it’s definitely worth the wait.

There are many benefits to growing your own shiitake mushrooms, including:
- They’re a delicious and nutritious addition to your diet.
