Mushrooms are a tasty treat, but they can be expensive. If you're a mushroom lover, you may want to consider growing your own. Mushrooms have very specific nutritional and environmental requirements, and creating the right conditions can be complex. Mushrooms require a cool, dark, damp environment, and the correct blend of nutrients. They extract the proteins and carbohydrates they need from a rich medium of decaying organic-matter vegetation. This matter is prepared into nutrient-dense substrate composts. Manure-based compost provides the proper levels of nitrogen mushrooms require to thrive. Animal manure is best due to its high nitrogen content, but poultry or sheep manure also works. Mushroom compost is a great addition to garden soil and can be used as a general fertilizer. It is a slow-release, organic plant fertilizer with high calcium levels, making it useful for growing fruits and vegetables.

Manure-based compost
Mushroom compost is a great addition to your garden, supporting the growth of various plants, from fruits and vegetables to herbs and flowers. It is a by-product of mushroom farming, containing a wide range of organic materials, including hay, straw, corn cobs, hulls, poultry or horse manure, and even cocoa shells.
To make your own manure-based compost for mushrooms, start by spreading a 6- to 8-inch layer of sawdust at the bottom of a compost bin. Thoroughly saturate the sawdust with water and let it sit overnight. The next day, cover the sawdust with a 2-inch layer of poultry or horse manure. It is important to note that cow manure should not be used as it is not as nitrogen-rich as chicken, turkey, or horse manure.
Turn the compost with a pitchfork daily to ensure the internal temperature does not exceed 160 degrees Fahrenheit. Cover the compost pile with a sheet to minimize heat loss. The compost will be ready for your mushroom beds in about two weeks, or when there is little to no temperature registered on a compost thermometer.
If you plan to use this compost to grow mushrooms, pasteurization is required to kill any remaining bacteria or weed seeds. This can be done by submerging the compost material in a cloth bag in a pot of boiling water for about an hour. After pasteurization, the compost can be inoculated with mushroom spores and used to grow mushrooms.
Mushroom compost can be used as a fertilizer and organic soil amendment, enriching the soil and supplying nutrients for the healthy growth of plants. It also increases the water-holding capacity of the soil, reducing the need for frequent watering. However, due to its high salt content, it should be avoided for salt-sensitive plants such as azaleas, rhododendrons, and camellias, as well as seedlings.

Pasteurisation
Pasteurization is a crucial step in mushroom cultivation that helps prepare the substrate for optimal mushroom growth. It involves reducing harmful pathogens and pests without eliminating beneficial microorganisms. This process creates an environment where the mushroom mycelium can thrive and grow without competition from other organisms. The primary goal of pasteurization is to give mushroom cultures a competitive advantage by reducing the number of competitors while retaining beneficial microbes that aid in nutrient breakdown and absorption.
There are several methods available for pasteurizing mushroom substrate, including both heat and cold techniques. One popular method is hot water pasteurization, which involves submerging the substrate in hot water between 149 and 167°F (65 and 75°C) for one to two hours. This temperature range kills heat-sensitive competitors while preserving beneficial heat-tolerant bacteria. It is important to monitor the water temperature to ensure it does not get too hot, as this can kill the beneficial bacteria.
Another method is cold water pasteurization, which can be achieved by soaking the substrate in cold water for 16 to 20 hours. This technique does not require heating and can be effective for small-scale operations or home cultivators. However, it may not be suitable for bulk substrate pasteurization due to the time and resources required.
A variation of cold water pasteurization is cold water lime pasteurization, which is a low-tech and cost-effective method. This process involves soaking the substrate in cold water treated with hydrated lime, which raises the pH to a level that kills mould spores, bacteria, and other contaminants. The recommended ratio is about 6 grams of hydrated lime per gallon of water, and the substrate should be soaked for 12 to 24 hours. This method is simple and effective, but it requires caution due to the chemical nature of lime.
Additionally, there are other innovative approaches to pasteurization, such as using laundry detergent or dish soap in cold water. These methods have shown promising results for home growers, but they may not be suitable for commercial operations. Overall, the choice of pasteurization method depends on various factors, including scale, resources, and the specific requirements of the mushroom variety.

Using mushroom compost as fertiliser
Mushroom compost is a by-product of mushroom farming. It is created from the substrate in which mushrooms are grown, which typically includes straw and well-rotted animal manure. After two to three crops of mushrooms have been harvested, the substrate is sterilised at high temperatures to remove any pests, diseases or weeds. It is then sold as a soil conditioner and mulch for ornamental and vegetable gardens.
Mushroom compost is an excellent soil conditioner and a great soil builder. It enhances the structure of your soil and provides nutrients for healthy plants. It also increases the water-holding capacity of the soil, which decreases the need for watering. It can be used as a general mulch, or spread as a thin layer on lawns, flower beds, and around trees and shrubs. It can also be used to improve waterlogged or clay soils, as well as light, free-draining soils.
When using mushroom compost, it is important to note that it has higher salt concentrations and alkaline levels than other types of compost. This means that it should not be used on salt-sensitive plants such as azaleas, rhododendrons, camellias, and other members of the Ericaceae family, as the high salt content can harm the plant. It should also not be used as a potting compost or for growing seeds or cuttings, as the salt can impact germination. To temper the alkaline levels, you can use aglime.
To use mushroom compost, mix it into the garden soil prior to planting. For flower beds and vegetable gardens, spread one to three inches of mushroom compost over the surface and till it into the top six inches of soil. For container plants, blend one part mushroom compost with three parts potting medium. For lawns, spread a thin layer over the surface as a top dressing.

Preparing mushroom substrate
Preparing a mushroom substrate is a crucial step in the mushroom cultivation process. It involves creating a medium that provides the necessary nutrition, moisture, and energy for mushrooms to grow and fruit. Here are some detailed instructions on how to prepare a mushroom substrate at home:
Selecting the Right Substrate
The choice of substrate depends on the species of mushrooms you plan to grow. Wood-based substrates, such as straw, sawdust, or hardwood, are optimal for certain mushrooms like reishi, lion's mane, and maitake. On the other hand, oysters are known to grow on almost any substrate. For beginners, cardboard is an excellent option as it is cheap, easily accessible, and retains moisture well while allowing for good air exchange.
Preparing the Substrate Mixture
The preparation of the substrate mixture can vary depending on the chosen substrate. Here are some common methods:
- Straw Substrate: Cut straw into three or four-inch pieces. You can either use 100% straw or mix it with supplements like coffee grounds for better results. Straw products containing eucalyptus should be avoided as eucalyptus can act as a fungicide. The straw substrate can be pasteurized through methods like cold water lime pasteurization or substrate fermentation.
- Cardboard Substrate: Collect cardboard and soak it in boiling water. Let it cool down, then squeeze out the excess water. You can then add mushroom pieces to start the colonization process.
- Coffee Grounds Substrate: Mix one kilogram of coffee grounds with 100 grams of mushroom spawn. For better air exchange and faster colonization, you can add 20% straw to the mixture.
- Coco Coir Substrate: This substrate involves mixing coco coir with boiling water. One recipe suggests using one brick of Coca-Cour with 8 cups of boiling water and 1 cup of gypsum. Another recipe uses a plain brick of coir with 4 quarts of boiling water.
Sterilization or Pasteurization
Before inoculating the substrate with mushroom spores or mycelium, it must be sterilized or pasteurized to eliminate any competing mold or bacteria. This step ensures that the desired mushroom species has the best chance to thrive. Commercial growers often pack sterilized substrate into large clear plastic bags, while home growers may use smaller containers like mason jars or buckets.
Once the substrate is prepared and sterilized, it's ready to be inoculated with mushroom spawn or spores, marking the beginning of the mushroom growing process.

Maintaining temperature
Temperature control is one of the most crucial factors in growing mushrooms. Mushrooms are one of the most delicate and temperamental crops, and even small temperature fluctuations can impact their growth rate and quality. Therefore, maintaining a consistent temperature is vital.
The ideal temperature range for mushroom growth varies depending on the species, but most mushrooms prefer a temperature range between 65-75 °F. During the incubation stage, which typically lasts two to three weeks, the temperature needs to be maintained between 65-75 °F (or 20-24 °C) to facilitate the formation of the mycelium, the vegetative part of the mushroom. The maximum tolerated temperature during incubation is around 28°C, but exceeding 25°C increases the risk of contamination. Once the mycelium has formed, the temperature needs to be lowered to around 60-65 °F (15-18 °C) to encourage the growth of the fruiting bodies. During the fruiting stage, most mushrooms cannot withstand temperatures above 23°C, except for certain tropical species such as the pink oyster mushroom.
To maintain the ideal temperature, you can use heaters or coolers with thermostatic controls, especially in climates prone to fluctuation. A thermometer or temperature sensor can help you monitor the temperature levels regularly and make any necessary adjustments. Additionally, you can use a cooling system such as an air conditioner or a water-cooling system to lower the temperature. These systems work by removing heat from the air and circulating cooler air back into the growing area. However, they can be expensive to install and operate.
If you are growing mushrooms indoors, make sure your space is well-insulated to avoid heat loss. Ventilation is also crucial, as it helps maintain even temperatures and avoids hot or cold spots. Use dedicated zones by dividing your space into different areas to adapt the temperature to each cultivation phase (incubation and fruiting). Regular air exchanges are essential, and you can use fans or open vents while ensuring the growing area is protected from contaminants.
