A New Way to Grow Mushrooms Outdoors, Create Productive Spaces, and Make the Most of Nature's Resources

Growing a vegetable garden is about more than just cultivating vegetables. You can also grow mushrooms—and you can do it outdoors by integrating them into vegetable gardens, home gardens, farms, and other productive landscapes through what we call Mushroom Beds.

Mushroom Beds are an outdoor cultivation technique that creates small, productive ecosystems where fungi transform organic matter into food. With relatively simple maintenance, they can continue producing mushrooms for several years.

Whether you're looking to become more self-sufficient and improve your food sovereignty, you're a market gardener seeking to diversify your production, or you're a landscaper or gardener searching for new ways to add value to green spaces, Mushroom Beds open up a world of possibilities.

What Is a Mushroom Bed?

Mushroom Beds are outdoor growing areas designed to allow the mycelium of a mushroom species to colonize an organic substrate and, when environmental conditions are right, produce mushrooms.

Unlike conventional indoor mushroom cultivation, the goal is not to control every aspect of the environment. Instead, we work with natural cycles of temperature, humidity, and seasonality, designing the growing system so that the fungus can thrive under outdoor conditions.

The result is a mushroom production system that is fully integrated into its surrounding environment.

A Mushroom Bed can become part of a vegetable garden, be established beneath trees, occupy an underused area of a garden, or be incorporated into a productive landscape design. With thoughtful planning, a single space can combine plants, fungi, and other elements of the ecosystem, creating multiple functions and harvests.

From the Traditional Vegetable Garden to the Fungal Garden

When we think of a vegetable garden, we usually imagine raised beds filled with vegetables. Yet a productive growing system can be much more than that.

Mushrooms enable us to make use of lignocellulosic materials—such as straw, wood chips, leaf litter, and other plant residues—by transforming them into productive growing substrates.

This introduces a new dimension to the design of agricultural spaces: growing plants above ground while cultivating mushrooms within the substrate itself.

It is a way of making use of different layers of the growing environment while incorporating fungi into more circular and regenerative production systems.

In addition, many mushroom species provide a seasonal harvest that complements vegetable production. When certain vegetable crops slow down or become less productive, mushrooms can fill that gap in the production calendar.

Field trials have also shown that introducing mycelium into vegetable-growing areas can stimulate root development in nearby plants, resulting in healthier, more vigorous crops with greater productive potential.

Designing the Growing System: Incubation and Fruiting

For a Mushroom Bed to succeed, simply adding mycelium to a pile of substrate is not enough. Understanding the needs of the fungus and carefully designing the growing environment are essential.

One of the key principles is to distinguish between two stages of development: incubation and fruiting.

During the incubation stage, the mycelium gradually colonizes the substrate. At this point, the goal is to provide conditions that allow the fungus to establish itself and compete successfully with other microorganisms.

Once the substrate has been sufficiently colonized and environmental conditions become favorable, the fruiting stage begins. This is when the mycelium shifts its energy from colonizing the substrate to producing mushrooms.

For this reason, when designing a Mushroom Bed, it is important to consider factors such as:

• Site selection and orientation

• Shade and solar exposure

• Available moisture

• Drainage

• The type and structure of the substrate

• Seasonal temperature patterns

• Ventilation and air circulation

• Competition from other organisms

• The mushroom species being cultivated

• And, above all, the species' natural fruiting season

There is no single design that works for every Mushroom Bed. Each system should be adapted to both the mushroom species and the environment in which it will be grown.

Two Species, Two Seasons

One of the most interesting possibilities offered by Mushroom Beds is combining species with different fruiting seasons.

Oyster Mushroom (Pleurotus ostreatus)

The oyster mushroom is one of the best-known and most rewarding species for anyone beginning to grow mushrooms.

It thrives in cool temperatures and, under suitable conditions, fruits mainly during autumn, winter, and spring.

An oyster Mushroom Bed can typically produce mushrooms from September through May, taking advantage of the cooler months of the year.

Pink Oyster Mushroom (Pleurotus djamor)

The pink oyster mushroom offers a particularly valuable characteristic: it is a thermophilic species adapted to warm temperatures. Its fruiting season is concentrated during the height of summer.

This makes it an ideal complement to the common oyster mushroom, extending mushroom production into the warmest months of the year. In our experience, it fruits reliably at ambient temperatures between 25°C and 35°C (77°F–95°F).

Together, these two Mushroom Beds illustrate one of the most interesting principles of outdoor mushroom cultivation: the goal is not simply to grow mushrooms, but to design a production calendar that follows the rhythm of the seasons.

Other species well suited to Mushroom Beds include the Wine Cap (Stropharia rugosoannulata), Enoki (Flammulina velutipes), the Straw Mushroom (Volvariella volvacea), and the Phoenix Oyster Mushroom (Pleurotus pulmonarius).

A Growing System That Can Last for Years

One of the greatest advantages of Mushroom Beds is that they are not designed as single-season crops.

When the substrate is appropriate, the mycelium becomes well established, and environmental conditions remain favorable, a Mushroom Bed can continue producing mushrooms for several years.

This completely changes the way we think about mushroom cultivation.

Rather than preparing a substrate, harvesting once or twice, and starting over, we are creating a living production system that evolves over time.

Managing a Mushroom Bed becomes a process of observation, understanding, and working with the system.

• When does it produce?

• When does production slow down?

• How does it respond to rainfall?

• How does the substrate change over time?

• How do shade and surrounding vegetation influence its performance?

This ongoing observation is one of the aspects that makes outdoor mushroom cultivation such a rewarding experience.

An Opportunity for Market Gardeners

For professional growers, integrating mushrooms into an existing production system represents an excellent opportunity for diversification.

Mushroom Beds can make productive use of areas that are often unsuitable for vegetable crops, such as shaded locations, field margins, spaces beneath trees, or transitional areas.

They also make it possible to extend the production calendar and complement the harvests from the vegetable garden.

Rather than replacing existing crops, they encourage us to ask a different question:

What else can this space produce?

This question is especially relevant today, as agriculture increasingly seeks systems that are more efficient, diverse, resilient, and based on the principles of circular resource use.

Mushroom Beds and Productive Landscaping

Mushroom Beds are not limited to vegetable gardens. A garden itself can also become a productive food-growing space.

In landscaping projects, edible gardens, educational farms, community gardens, and agroecological systems, mushrooms can become a natural part of the overall design.

Imagine shaded areas where perennial plants, fruit trees, aromatic herbs, and Mushroom Beds coexist—spaces where food production, biodiversity, and landscape design are no longer separate concepts but work together as one living system.

For landscape designers and gardeners, this opens exciting opportunities to incorporate outdoor mushroom cultivation into resilient, multifunctional landscapes.

Growing Mushrooms Is Also About Growing Self-Reliance

Outdoor mushroom cultivation invites us to see gardens and agricultural landscapes from a different perspective.

It shows us that mushrooms do not need to be confined to climate-controlled growing rooms or sophisticated facilities. They can become an integral part of a vegetable garden, a home garden, or a farm.

Above all, it reminds us of a simple but powerful idea: food production can be far more diverse, accessible, and closely connected to nature than we often imagine.

By incorporating mushrooms into our production systems, we discover new ways to use available resources, diversify our harvests, move toward greater self-reliance, and reconnect with the natural cycles that surround us.

For this reason, Mushroom Beds are much more than a cultivation technique. They invite us to rethink our gardens, farms, and outdoor spaces as living, productive ecosystems that are more resilient, more diverse, and better adapted to the future.
