Can You Grow Mushrooms On Woodchips?

Yes, you absolutely can grow mushrooms on woodchips. Woodchips provide an excellent growing medium for a variety of mushroom species, making it a popular choice among mushroom enthusiasts and commercial growers alike. The process of growing mushrooms on woodchips is relatively simple and can yield a bountiful harvest. In this article, we will explore what woodchips are, why they are a great medium for mushroom cultivation, the types of mushrooms that grow well on woodchips, and the steps involved in successfully growing mushrooms on woodchips.

What Are Woodchips?

Woodchips are small pieces of wood that are typically derived from tree branches, trunks, or logs. They can vary in size and composition, ranging from finely shredded pieces to larger chunks. Woodchips are commonly used as mulch in gardening and landscaping projects, acting as a protective layer that helps retain moisture, suppress weeds, and regulate soil temperature.

Why Would You Want to Grow Mushrooms on Woodchips?

Growing mushrooms on woodchips offers several advantages. Firstly, woodchips provide a nutrient-rich substrate for mushrooms to thrive on. Unlike other growing mediums, such as straw or sawdust, woodchips contain a higher content of lignocellulosic material that mushrooms can readily decompose and convert into nutrients. This makes woodchips an ideal food source for many mushroom species.

Secondly, woodchips are widely available and relatively inexpensive compared to other growing mediums. They can often be sourced locally or even produced at home using yard waste or fallen tree branches. This accessibility makes woodchips a cost-effective option for mushroom cultivation.

Lastly, growing mushrooms on woodchips promotes sustainability by utilising organic waste material. Instead of letting woodchips go to waste or contributing to landfill, you can repurpose them to cultivate delicious and nutritious mushrooms.

Types of Mushrooms That Grow Well on Woodchips

Several mushroom species are well-suited for cultivation on woodchips. One popular choice is the oyster mushroom, which is known for its versatility and adaptability to different growing conditions. Oyster mushrooms are fast-growing, have a delicate texture, and a mild flavour, making them a favourite among mushroom lovers.

Another type of mushroom that thrives on woodchips is the shiitake mushroom. Shiitake mushrooms are highly valued for their rich flavour and numerous health benefits. They are widely used in Asian cuisine and have gained popularity worldwide.

Other mushrooms that can be successfully grown on woodchips include lion’s mane, wine cap, and almond agaricus. Each mushroom species has its own unique characteristics and growing requirements, so it’s essential to choose a type that aligns with your preferences and resources.

Selecting the Right Woodchips

When selecting woodchips for growing mushrooms, it’s important to consider the type of wood and its condition. Hardwoods are preferred over softwoods. Hardwoods generally contain higher nutrient levels and have a lower risk of contaminating fungi, making them more suitable for mushroom cultivation.

Additionally, the woodchips should be relatively fresh and free from any chemical treatments, such as wood preservatives or pesticides. It’s best to avoid woodchips from diseased trees or those that have been in contact with toxins, as these can negatively impact mushroom growth and health.

Preparing the Woodchips

Before using the woodchips, it’s crucial to properly prepare them to create a favourable environment for mushroom colonisation and growth. This involves a process called “sterilisation.” Sterilisation can be achieved through various methods, including pasteurisation or boiling.

Pasteurisation involves heating the woodchips to a specific temperature range (around 70-85°C or 158-185°F) for a certain duration to eliminate competing organisms and pathogens without completely sterilising the substrate. Boiling is another method that can be used for smaller batches of woodchips. It involves submerging the woodchips in boiling water for approximately 30 minutes.

Once sterilised, the woodchips need to be cooled and adequately drained to remove excess moisture. Properly preparing the woodchips helps create a clean and supportive environment for mushroom mycelium to colonise and grow.

Inoculating the Woodchips

After preparing the woodchips, they are ready to be inoculated with mushroom spawn. Mushroom spawn is essentially the “seed” or mycelium of the mushroom, which will grow and eventually produce mushrooms. You can either purchase mushroom spawn from a reputable supplier or produce your own by collecting mycelium from mature mushrooms.

To inoculate the woodchips, mix the spawn thoroughly with the prepared woodchips. It’s crucial to ensure even distribution of the spawn to maximise the chances of successful colonisation. You can use a clean plastic bag, container, or even directly inoculate outdoor woodchip beds.

Maintaining Moisture Levels

To support healthy mushroom growth, it’s important to maintain optimal moisture levels in the woodchip bed. Mushrooms require consistent humidity, but excessive moisture can lead to the growth of moulds or harmful bacteria. Regularly monitor the moisture levels by checking the woodchips’ moisture content and adjusting as necessary.

Watering the woodchip bed may be required, especially during dry periods or when the woodchips start to appear dry. Use clean, non-chlorinated water and avoid drenching the bed. Mist the surface lightly or use a sprinkler system to ensure even moisture distribution.

Controlling Temperature

Mushrooms have specific temperature requirements for fruiting, and maintaining the appropriate temperature is vital for successful woodchip cultivation. Different mushroom species have varying temperature preferences, but most commonly cultivated mushrooms thrive in the range of 60-75°F (15-24°C).

To regulate temperature, consider the seasonal climate and environmental factors. You can use shade cloth or cover the woodchip bed to protect it from extreme heat or cold. Additionally, using temperature-controlled indoor growing spaces or shade structures can help create optimal conditions for consistent mushroom production.

Protecting the Mushroom Bed

As the mushrooms grow, it’s crucial to protect the woodchip bed from pests, wildlife, and harsh weather conditions. You can use physical barriers, such as fencing or netting, to prevent animals from damaging the bed or consuming the mushrooms. Applying a layer of straw mulch on top of the woodchips can also provide additional insulation and protection.

Regular inspections of the woodchip bed are necessary to identify and address any potential issues promptly. Prompt action can help prevent the spread of diseases or pests, ensuring the continued health and productivity of your mushroom bed.

Harvesting and Caring for Woodchip-Grown Mushrooms

Harvesting woodchip-grown mushrooms is an exciting and rewarding experience. Harvest timing varies depending on the mushroom species, but generally, mushrooms should be harvested when the caps have fully expanded but before they start to flatten or develop gills that release spores.

To harvest mushrooms, gently twist or cut them at the base of the stem. Avoid leaving any remains behind to prevent contamination or the growth of competing organisms. Properly store harvested mushrooms in a cool, dark place to maintain their quality and extend their shelf life.

Caring for the woodchip bed between harvests is essential for continuous mushroom production. Regularly inspect the bed for any signs of contamination, pests, or diseases. Maintaining proper moisture levels and temperature, as mentioned before, is crucial for supporting ongoing mushroom growth.

In conclusion, growing mushrooms on woodchips is an enjoyable and rewarding endeavour. By understanding the process, selecting the right woodchips, providing optimal conditions, and caring for the mushroom bed, you can cultivate a diverse range of delicious and nutritious mushrooms right in your own backyard. So grab your woodchips, choose your favourite mushroom species, and embark on an exciting journey into the world of woodchip-based mushroom cultivation!
