How to Grow Muchrooms?

To grow mushrooms, you can either grow them indoors in a controlled environment or outdoors on hardwood logs.

Indoor growing usually yields better results, while log-grown mushrooms are generally more successful outdoors.

For indoor growing, you can use mushroom spawn in beds or boxes filled with manure or compost, or a mushroom growing kit with spawn and growing media.

Logs can be used by tapping wooden dowels or plugs impregnated with spawn into pre-drilled holes in the log.

Mushrooms need to be grown under-cover, away from sunlight, at a temperature of around 15°C.

A rich and moisture-retentive growing medium, such as horse manure, is needed.

Spread the spawn on the surface, mix it in, cover with damp newspaper, and then with garden soil or compost mixed with lime.

Water as required to keep the medium moist.

Mushrooms should start appearing after a few weeks.

For log-grown mushrooms, use hardwood logs and implant dowels within six weeks of cutting.

Different types of mushrooms can be grown at home, and mushroom spawn and dowels can be purchased from reputable suppliers.

Maintaining the right temperature and lighting conditions is crucial.

Harvest the mushrooms when the caps open, using a sharp knife.

Use harvested mushrooms within a few days, as they only keep for a short time in the fridge.

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. This ensures that the mushrooms receive the optimal conditions for growth. On the other hand, outdoor cultivation of mushrooms on hardwood logs tends to be more successful, as it mimics the natural environment in which mushrooms thrive.

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:

  1. Prepare the bed or box by filling it with a suitable growing medium such as manure or compost.
  2. Spread the mushroom spawn evenly on the surface of the medium and mix it in thoroughly.
  3. 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.
  4. 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.
