How to grow mushrooms outside


Mushrooms🍄 are fungi that thrive in various environments, including forests, fields, and even your own backyard.

Growing mushrooms outside offers several advantages, including lower initial investment and a more natural growing environment.

By following a few essential steps, you can cultivate your own mushrooms and enjoy a bountiful harvest.

Choosing the Right Mushroom Species

When it comes to growing mushrooms outside, selecting the right mushroom species is crucial for a successful harvest. Different mushroom varieties have different growth requirements and preferences.

Here are a few popular mushroom species that can be grown outdoors: 👇

Shiitake Mushrooms

Shiitake mushrooms (scientific name: Lentinula edodes) are one of the most popular and widely cultivated mushroom species in the world. They have a meaty texture and a rich, earthy flavor that is highly prized in culinary preparations.

Shiitake mushrooms thrive in a temperate climate and are known for their ability to grow on hardwood logs.

Oyster Mushrooms

Oyster mushrooms (scientific name: Pleurotus spp.) are another excellent choice for outdoor cultivation. They come in various colors, including white, yellow, and pink, and have a delicate, mild flavor.

Oyster mushrooms can be grown on a wide range of substrates, including straw, sawdust, and coffee grounds.

Wine Cap Mushrooms

Wine cap mushrooms (scientific name: Stropharia rugosoannulata) are a unique and flavorful mushroom species that can be grown directly in garden beds or mulched areas. They have a deep red cap and a complex, nutty flavor.

Wine cap mushrooms are known for their ability to improve soil health and can be an excellent addition to any permaculture garden.

Preparing the Outdoor Mushroom Bed

To create an ideal environment for mushroom cultivation outside, you’ll need to prepare a dedicated mushroom bed. Follow these steps to set up your outdoor mushroom bed:

Preparing the Outside Mushroom Bed

1. Select a suitable location: Choose a shaded area in your garden that receives indirect sunlight. Avoid areas with excessive wind exposure or heavy foot traffic.

2. Clear the area: Remove any grass, weeds, or other vegetation from the selected location. It’s essential to create a clean and sterile environment for the mushrooms to grow.

3. Prepare the soil: Loosen the topsoil using a garden fork or tiller. This will improve the soil’s texture and allow for better moisture retention.

4. Add organic matter: Incorporate well-rotted organic matter, such as compost or aged manure, into the soil. This will enrich the soil with essential nutrients and provide a fertile substrate for the mushrooms.

Selecting the Growing Location

The success of your outdoor mushroom cultivation largely depends on selecting the right growing location. Here are some factors to consider when choosing the ideal spot:

1. Shade and indirect sunlight: Mushrooms prefer a shady environment with indirect sunlight. Avoid areas that receive intense, direct sunlight as it can dry out the mushroom bed and hinder growth.

2. Protection from wind: Strong winds can dehydrate the mushroom bed and cause damage to the delicate mushroom caps. Choose a location that is sheltered from heavy wind exposure.

3. Accessibility to water: Ensure that the chosen location is easily accessible to a water source. Mushrooms require consistent moisture levels for optimal growth.

Providing the Ideal Growing Conditions

Creating the ideal growing conditions is crucial for the success of your outdoor mushroom cultivation. Here are some key factors to consider:

Temperature and Humidity

Mushrooms thrive in specific temperature and humidity ranges. While the exact requirements vary depending on the mushroom species, most mushrooms prefer temperatures between 60°F and 75°F (15°C and 24°C) and humidity levels around 80%.

Moisture Management

Maintaining adequate moisture levels is essential for mushroom growth. Regularly monitor the moisture content of the mushroom bed and provide water as needed to keep the substrate damp but not saturated.

Use a watering can or a misting spray bottle to avoid disturbing the mushroom mycelium.

Mulching and Covering

Mulching the mushroom bed with a layer of organic matter, such as straw or wood chips, helps retain moisture and regulate temperature.

Additionally, covering the mushroom bed with a breathable material, like a shade cloth or burlap, can further protect it from excessive sun exposure and help maintain the required humidity levels.

Planting Mushroom Spores or Spawn

Once your outdoor mushroom bed is prepared, it’s time to plant mushroom spores or spawn.

Mushroom spores are tiny reproductive cells, while spawn refers to the mycelium (the vegetative part of the fungus) grown on a suitable substrate.

Planting Mushroom Spores or Spawn

Here’s how to proceed: 👇

1. Choose high-quality spores or spawn: Purchase spores or spawn from a reputable supplier to ensure healthy and vigorous mushroom growth.

2. Prepare the substrate: If you’re using mushroom spores, mix them with a sterile substrate, such as sawdust or sterilized compost. If you’re using spawn, simply distribute it evenly throughout the mushroom bed.

3. Cover with a protective layer: After spreading the spores or spawn, cover the mushroom bed with a thin layer of moistened soil or additional substrate. This layer will protect the spores or spawn from drying out and provide an ideal environment for colonization.

Maintaining the Mushroom Bed

To ensure the healthy development of your outdoor mushroom bed, it’s important to provide proper maintenance.

Here are some essential tasks to perform:

1. Watering: Regularly check the moisture levels in the mushroom bed and water as needed to maintain a consistently damp environment. Be careful not to overwater, as excessive moisture can lead to fungal diseases.

2. Weed control: Monitor the mushroom bed for weed growth and remove any competing plants. Weeds can deplete nutrients and moisture from the substrate, hindering mushroom growth.

3. Mulch replenishment: As the mulch layer decomposes over time, periodically replenish it to maintain adequate moisture retention and temperature regulation.

4. Monitoring for pests and diseases: Keep an eye out for common mushroom pests, such as slugs or snails, and address any signs of disease promptly. Remove any contaminated mushrooms or substrate to prevent the spread of infections.

Harvesting and Storing Mushrooms

The time it takes for mushrooms to grow and mature varies depending on the species and environmental conditions. Generally, you can expect to harvest mushrooms within a few weeks to a few months after planting.

Harvesting and Storing Mushrooms

Here are some tips for harvesting and storing your outdoor-grown mushrooms:

1. Harvesting: When the mushroom caps are fully developed and before they begin to release spores, gently twist or cut the mushrooms at the base. Harvesting at the right time ensures optimal flavor and texture.

2. Storing: To store harvested mushrooms, place them in a paper bag or a breathable container and store them in the refrigerator. Avoid using plastic bags, as they can trap moisture and cause the mushrooms to deteriorate quickly. Freshly harvested mushrooms can be stored for up to a week.

Common Problems and Solutions

Problem: Mushroom bed drying out too quickly.

Solution: Increase the mulch layer and water the bed more frequently to maintain moisture levels.

Problem: Mushrooms are growing slowly or not at all.

Solution: Check the temperature and humidity levels. Adjust the growing conditions accordingly, ensuring that they fall within the optimal range for your chosen mushroom species.

Problem: The mushroom bed is infested with pests.

Solution: Remove the affected mushrooms and inspect the bed for pests. Introduce natural predators like nematodes or beneficial insects to control the pest population.

Problem: Mushrooms are discolored or have an unpleasant odor.

Solution: This may be a sign of fungal contamination or improper growing conditions. Remove the affected mushrooms and adjust the environmental factors accordingly.


learning how to grow mushrooms outside can be a fascinating and rewarding endeavor. By following the steps outlined in this guide, you can create an ideal environment for outdoor mushroom cultivation and enjoy a bountiful harvest of delicious fungi.

Remember to choose the right mushroom species, prepare the mushroom bed properly, and provide the ideal growing conditions.

With patience and care, you’ll soon be enjoying the fruits of your labor, savoring the unique flavors and textures of homegrown mushrooms.
