Did You Know?
1. The largest organism on Earth is not an animal or a plant, but a mushroom. In Oregon’s Malheur National Forest, a honey mushroom (Armillaria ostoyae) covers an astonishing 2,385 acres of land.
2. Mushrooms play a crucial role in decomposing organic matter, aiding in recycling nutrients back into the ecosystem. Without mushrooms, dead trees and other plant material would accumulate, leading to a much slower nutrient cycling process.
3. In traditional Chinese medicine, the Ganoderma lucidum, also known as the lingzhi mushroom or “mushroom of immortality,” has been used for over 2,000 years as a remedy for various ailments and as a general health tonic.
4. Certain mushrooms have the ability to glow in the dark, a phenomenon called bioluminescence. One example is the Panellus stipticus, found in North America, Europe, and Asia. This luminous mushroom emits a soft green glow that can last for several hours.
5. The fly agaric (Amanita muscaria) mushroom, with its iconic red cap and white spots, is commonly associated with fairy tales and folklore. However, it is highly toxic and classified as a hallucinogen. In some cultures, shamans would consume this mushroom to induce altered states of consciousness during spiritual rituals.
Indoor Vs Outdoor Mushroom Growing
Growing mushrooms can be done both indoors and outdoors, each with its own advantages and considerations. Indoor growing in a controlled environment usually gives the best results, as it allows for precise regulation of temperature, humidity, and lighting conditions.

Outdoor Mushroom Growing on Hardwood Logs
Growing mushrooms on hardwood logs is a popular and low-maintenance method that involves tapping wooden dowels or plugs impregnated with spawn into pre-drilled holes in the log. The logs should ideally be freshly cut and the dowels inserted within six weeks of cutting. The best woods to use for log-grown mushrooms are oak, beech, hornbeam, chestnut, hazel, birch, maple, or holly.
Once the dowels are inserted into the logs, they require less attention. It is important to choose a shady spot for the logs and keep them moist. Depending on the type of mushroom, harvest time can vary, with some mushrooms taking up to 18 months to appear.
Growing Mushrooms In Beds Or Boxes
Growing mushrooms in beds or boxes is a common method for indoor cultivation. When choosing this method, it is important to ensure that the growing medium is rich, fertile, and moisture-retentive. Mushroom spawn, which can be purchased from specialist mushroom suppliers or some vegetable seed suppliers, is used in combination with the growing medium.
To get started with this method, follow these steps:
- Prepare the bed or box by filling it with a suitable growing medium such as manure or compost.
- Spread the mushroom spawn evenly on the surface of the medium and mix it in thoroughly.
- To provide optimal growing conditions, cover the bed or box with damp newspaper and then a layer of garden soil or compost mixed with lime.
- It is crucial to maintain the moisture level of the growing medium. Water it as required using a spray attachment or a watering can with a fine rose.
After several weeks, mushrooms should start appearing. Harvest them when the caps open, and cut them with a sharp knife. By harvesting every day, you can expect a continuous crop for approximately six months. If needed, you can add fresh spawn to the bed or box to encourage further mushroom growth.
Remember: mushrooms thrive in a moist and controlled environment. With the right growing medium and proper care, you can enjoy a bountiful harvest of delicious mushrooms.

Growing Mushrooms On Hardwood Logs
Growing mushrooms on hardwood logs is a fantastic option if you prefer an outdoor cultivation method. This technique involves using wooden dowels or plugs impregnated with mushroom spawn to cultivate mushrooms on freshly cut hardwood logs. However, it is important to note that conifers should be avoided as they are not suitable for this method.
To start growing mushrooms on logs, follow these steps:
- Obtain hardwood logs from healthy trees.
- Cut the logs into suitable lengths.
- Drill holes into the logs.
- Insert the impregnated dowels or plugs into the pre-drilled holes.
- Ensure the dowels or plugs are not more than six weeks old.
- The best woods to use for log-grown mushrooms include oak, beech, hornbeam, chestnut, hazel, birch, maple, or holly.
Once the dowels are inserted, the logs require less attention. Place the logs in a shady spot and keep them moist to encourage mushroom growth. Depending on the type of mushroom, it may take up to 18 months for mushrooms to appear. Regularly check the logs and harvest the mushrooms when they reach the desired size.
Optimal Conditions For Mushroom Growth
Creating the optimal conditions for mushroom growth is crucial for successful cultivation. Mushrooms prefer dark, cool, and humid environments with temperatures ranging between 55°F and 60°F. While some mushrooms can tolerate some light, it is important to ensure that the growing area stays mostly dark or in low light.
To provide the ideal temperature and humidity level for mushroom growth, it is recommended to grow them indoors in a controlled environment. Maintaining a temperature of around 15°C (59°F) and a humidity level of 80-90% is ideal. This can be achieved by using a humidifier or by misting the growing area with water regularly.
Choosing The Right Growing Medium For Mushrooms
Selecting the appropriate growing medium for mushrooms is crucial to provide them with the necessary nutrients for growth. Mushrooms have the ability to grow on various substances such as sawdust, grain, straw, or wood chips. The choice of growing medium depends on the mushroom species being cultivated.
When growing mushrooms in beds or boxes, a rich and fertile growing medium such as horse manure, compost, or a mixture of both is commonly used. The mushroom spawn is mixed into the growing medium to encourage colonization. For log cultivation, the hardwood logs themselves act as the growing medium, with the spawn being inserted into pre-drilled holes in the logs.
6. Harvesting And Storage Of Mushrooms
Once the mushrooms have reached the desired size, it is time to harvest them. Harvesting should be done when the caps of the mushrooms have opened but before the gills are fully exposed. Use a sharp knife to cut the mushroom at the base of the stem.
For a continuous crop, it is recommended to harvest mushrooms every day. This ensures that new mushrooms can continue to grow. With proper care and maintenance, a single mushroom bed or box can provide a continuous crop for approximately six months.
Once harvested, mushrooms should be used within a few days, as they have a short shelf life. Store them in a cool, dry place or in the refrigerator to maintain their freshness. However, it is important to note that mushrooms should not be refrigerated for too long, as they tend to lose flavor and texture over time.
In conclusion, growing mushrooms can be a rewarding and enjoyable hobby. Whether you choose indoor or outdoor cultivation, beds or boxes, or log-grown mushrooms, the key is to provide the optimal growing conditions and select the appropriate growing medium for the mushroom species. With patience, care, and the right resources, you can enjoy a bountiful harvest of delicious mushrooms.
