How To Grow Portobello aka Swiss Brown, Button Mushroom

Preparation

1. Wash your hands thoroughly and put on latex gloves.
2. Sterilize your workspace by wiping it down with isopropyl alcohol.

making Portobello Substrate

1. Visit a local hardware store or gardening center to purchase bags of horse and cow manure. These are often available in dried or composted forms, or in bagged form
2. In a large container or wheelbarrow, combine the horse and cow manure with straw in a 50/50 ratio. For example, use 2 parts manure and 2 parts straw.
3. Ensure the straw is well-distributed throughout the mixture to create a more visually prominent appearance.

Moistening the Substrate

Gradually add water to the mixture, stirring continuously, until the substrate reaches a consistency similar to a wrung-out sponge. Ensure it is evenly moistened throughout, grab a handful of substrate and squeeze it as hard as possible only a couple of drops of water should fall out.

Pasteurization Of your Substrate

To prevent contamination, you can either sterilize or pasteurize the substrate. Sterilization involves heating the substrate to kill all microorganisms, while pasteurization involves heating to reduce competition from harmful organisms. Put you substrate in your bag or container you wise to grow your mushrooms in.

1. Pasteurize by immersing the bags or containers in hot water (around 160-180°F or 71-82°C) for 1-2 hours.
2. Sterilize by placing the bags or containers in a pressure cooker or an oven at a temperature of around 250°F (121°C) for 2-3 hours.

Cooling your portobello substrate

Properly managing the cooling phase of your Portobello substrate is a crucial step in ensuring a successful cultivation process. Allowing the substrate to cool completely serves as a strategic measure aimed at mitigating the risk of contamination during the subsequent inoculation steps. By patiently waiting for the substrate to reach an optimal temperature, you create an environment that is less conducive to the growth of unwanted microorganisms, which could potentially compromise the integrity of your mushroom culture. This cooling period not only fosters a more sterile and controlled setting but also facilitates the development of a favorable foundation for the mycelium to thrive when introduced. It is essential to exercise patience and adhere to this cooling regimen as part of a meticulous and disciplined approach to cultivating Portobello mushrooms, ultimately contributing to the overall success and health of your mushroom crop.

Inoculating your Portobello substrate

In the critical phase of inoculation, it becomes imperative to exercise precision and adherence to the established guidelines. Following the meticulous cooling of the substrate to ensure an optimal environment, the subsequent step involves the deliberate introduction of Portobello mushroom spores into the substrate. This procedure, as elaborated in the preceding instructions, necessitates a careful approach to guarantee the successful initiation of mycelial growth. By methodically implementing the recommended inoculation techniques, you not only bolster the chances of a robust mushroom culture but also fortify the substrate against potential contaminants. This strategic and well-considered process marks a pivotal stage in the cultivation of Portobello mushrooms, laying the groundwork for a flourishing mycelial network and, eventually, a bountiful harvest.

Incubating of Your Mushrooms

1. Place the sealed bags or containers in a warm, dark place (around 75-80°F or 24-27°C) for about 2-3 weeks.
2. Check periodically for any signs of contamination, such as strange colors or smells. If you notice anything unusual

Fruiting Portobello Mushroms

Prepared Substrate:

Ensure that your Portobello mushroom substrate has been properly inoculated and incubated according to the instructions provided earlier.

Casing Material Preparation:

1. In a clean container, mix peat moss and vermiculite in a 1:1 ratio. For example, if you have 2 cups of peat moss, mix it with 2 cups of vermiculite.
2. Gradually add water to the mixture, stirring continuously, until the casing material reaches a damp but not soggy consistency.

Applying the Casing Layer:

1. Wear latex gloves and gently apply a layer of the casing material on top of the fully colonized substrate. Aim for a thickness of about 1/2 to 3/4 inch (1.3 to 1.9 cm).
2. Ensure an even distribution of the casing layer to cover the entire surface of the substrate.

Smoothing and Leveling:

1. Use a clean, flat tool (like a sterile spatula or the back of a clean spoon) to smooth and level the casing layer. This helps create an even surface for mushroom pins to form.

 Fruiting Chamber Setup:

1. Place the substrate with the casing layer in a well-ventilated and well-lit area. A temperature of around 55-70°F (13-21°C) is suitable for the fruiting stage.
2. Maintain humidity by misting the casing layer with water. Use a mist bottle to avoid disturbing the substrate.

Pin Formation and Development

1. In the coming days, you should start to see small mushroom pins forming on the surface of the casing layer.
2. Continue misting to maintain proper humidity levels. Avoid over-misting to prevent excessive moisture accumulation.

Mushroom Growth

As the mushrooms grow, adjust the conditions as needed. Ensure good air circulation and proper lighting to encourage healthy mushroom development.

Harvesting

Once the Portobello mushrooms have fully developed caps and are of desired size, carefully twist or cut them at the base to harvest. b. Harvest all mature mushrooms, leaving the smaller ones to continue growing.

Second and Subsequent Flushes

After the initial harvest, continue misting and maintaining proper conditions for potential second and subsequent flushes of mushrooms.

By incorporating a casing layer into the fruiting process, you provide an additional layer of support for the development of Portobello mushrooms, enhancing the chances of a successful and bountiful harvest.

Growing Portobello in Bags

In conclusion, Growing Portobello in Bags is a rewarding and educational process that involves careful preparation, attention to detail, and patience. Starting with a well-balanced substrate of horse and cow manure mixed with straw creates an ideal environment for mycelium colonization. Sterilization or pasteurization is crucial to eliminate potential contaminants, ensuring a healthy substrate.

The introduction of a casing layer, composed of peat moss and vermiculite, serves as a beneficial microenvironment for the development of mushroom pins and subsequent fruiting bodies. Providing the right conditions, including proper humidity, ventilation, and lighting, is essential during the fruiting stage.

Throughout the cultivation journey, it’s crucial to maintain cleanliness, monitor for signs of contamination, and adjust environmental factors as needed. The process offers not only a hands-on experience in mushroom cultivation but also a deeper understanding of mycology and the intricate life cycle of Portobello mushrooms.

As growers observe the emergence of mushroom pins, carefully harvest mature specimens while leaving smaller ones to encourage additional flushes. The continuous misting and maintenance of optimal conditions can lead to multiple harvests, providing a sustained and fruitful cultivation experience.

In essence, Learning how to grow Portobello mushroom is not only about producing a delicious and nutritious culinary ingredient but also about fostering curiosity, responsibility, and a connection to the natural world. The process serves as a valuable educational tool, demonstrating the symbiotic relationship between humans and fungi while instilling a sense of accomplishment in the cultivation of a widely enjoyed and versatile mushroom.
