Oyster mushrooms are easy to grow and have many health benefits
Oyster mushrooms are a great choice for new growers, hobbyists, and small-scale farmers as they are one of the easiest mushrooms to grow. They can be grown on a wide variety of substrates, including hardwood sawdust, soy hulls, wheat straw, sugarcane, coffee grounds, banana leaves, cardboard, and coco coir. Oyster mushrooms are "primary decomposers", meaning they can break down any "ligninous" tissue and use it for food. They can even feed off of straight motor oil!
Oyster mushrooms are also highly sought after for their culinary uses, as all parts of the mushroom are edible, including the caps, gills, and stems. They have a sweet, delicate taste, and some types have an anise-like scent, while others, like the yellow oyster mushroom, have a fruity aroma.
In addition to their culinary uses, oyster mushrooms offer a plethora of health benefits. They are low in calories and rich in vitamins and minerals, including vitamin B3, riboflavin, potassium, vitamin B6, folic acid (folate), magnesium, vitamin C, pantothenic acid, and amino acids. Oyster mushrooms are also a fantastic addition to a gluten-free diet and can help maintain a strong immune system.
Research suggests that oyster mushrooms may also have positive effects on heart health by reducing risk factors such as high cholesterol and high blood pressure. This is due to the presence of beta-glucans, fibers that make up the cell walls of yeast and fungi. When fermented by gut bacteria, beta-glucans produce short-chain fatty acids that help reduce cholesterol production in the body. Oyster mushrooms may also help regulate blood sugar levels and have potential anti-tumor, anti-inflammatory, and gut health-promoting properties.
With their ease of cultivation and numerous health benefits, oyster mushrooms make a great addition to any diet or gardening hobby.

Choose a mushroom type—phoenix, golden, pink, pearl, blue, etc
Oyster mushrooms are available in a wide range of varieties, each with distinct characteristics. The most common type is the Pearl Oyster, particularly in North America. It has a slightly sweet and woody taste, with a mild and tender texture. If you're looking for a more complex and aromatic flavour, the Golden Oyster is a bright yellow variety with small caps. For a vivid splash of colour, consider the Pink Oyster, also known as the Flamingo Oyster, which has a ruffled appearance. However, note that its attractive pink hue fades when cooked.
If you're interested in a variety that prefers warmer weather, the Phoenix Oyster is similar in flavour to the Pearl Oyster but with smaller, paler caps and a longer stem. It tends to grow in late summer. For a unique appearance, the Blue Oyster has dark caps and pale gills, creating a striking contrast. Despite its name, it is grey with only a slight bluish hue, and its taste is identical to the Pearl Oyster.
When choosing a mushroom type, consider factors such as colour, flavour, texture, and the growing conditions they require. Some varieties, like the Pink Oyster, have a short shelf life and don't transport well, so they may be harder to come by. On the other hand, the Golden Oyster is delicate and doesn't travel well due to its tendency to break or tear with too much handling. Thus, you're most likely to find them at farmers' markets.
Ultimately, the variety you choose will depend on your personal preferences and the specific growing conditions you can provide. Each type has its own unique characteristics, so explore the options and select the one that appeals to you the most.

Prepare a substrate—straw, sawdust, cardboard, coffee grounds, etc
Oyster mushrooms can grow on a variety of substrates, including straw, sawdust, cardboard, and wild grasses.
When using straw as a substrate, wheat and oat straw are the most popular choices. However, any dried stalks from grass species, including wild species, can be used as long as they are properly processed. Straw is typically pasteurized before use.
Sawdust is another popular option for growing oyster mushrooms. This method mimics the natural environment where these mushrooms flourish—on the forest floor, decomposing fallen trees and branches. Hardwood sawdust from oak, beech, or maple is ideal. It's important to ensure the sawdust is from untreated wood to avoid harmful chemicals. The sawdust is then inoculated with mushroom spawn and provided with the right conditions for growth.
Cardboard can also be used as a substrate for oyster mushrooms. The corrugated inner lining of cardboard sheets is soaked in water for an hour or so until completely saturated. It is then drained and placed in layers inside an airtight container. The cardboard provides a suitable environment for the mycelium to grow, as it is made up of lignin and cellulose, which the oyster mushrooms feed on.
Wild grasses can be used as a substrate for oyster mushrooms as well. The dried stalks of any grass species can be processed properly and used as a nursery or spawn-generating material.

Pasteurise the substrate—soak in hot water or a lime bath
Oyster mushrooms are hardy, fast-growing species that can be grown on a variety of substrates, including hardwood sawdust, straw, sugarcane, coffee grounds, and cardboard. Before introducing the mushroom spawn to the substrate, it is important to pasteurize the substrate to prevent contamination.
One method of pasteurization is hot water pasteurization, which involves submerging the substrate in boiling water above 176 °F (80 °C) for at least 2 hours. This method is considered effective in killing off contaminants but may be less safe and energy-efficient, especially when dealing with large quantities of substrate.
Another method is cold water pasteurization, which is a low-tech, inexpensive, and effective way to pasteurize the substrate for growing oyster mushrooms. This method is ideal for beginners as it doesn't require specialized equipment and is safer and more energy-efficient. One popular technique within cold water pasteurization is the lime bath method, which uses hydrated lime to raise the pH of the water and kill living organisms. The lime solution is very caustic, so it is important to wear protective clothing, gloves, and eye protection when handling it. Other substances that can be used in a cold water bath for pasteurization include wood ash, soap, bleach, chlorine, vinegar, and hydrogen peroxide.
When using the lime bath method, the size of the container and the amount of substrate to be pasteurized must be considered. A 55-gallon (200-liter) drum, large tote, or 5-gallon (20-liter) bucket can be used, depending on the amount of substrate. The substrate should be placed in a net or mesh bag, an old pillowcase, or a plastic laundry basket to hold it submerged in the lime bath. The substrate should be soaked in the lime bath for 16 to 20 hours, during which time the rapid change in pH ruptures the cell walls of organisms, causing them to die.

Add mycelium—from store-bought mushrooms or a petri dish
Oyster mushrooms can be grown from mycelium sourced from store-bought mushrooms or a petri dish. Mycelium is the root-like vegetative growth of the fungus and is critical to the cultivation of oyster mushrooms.
Using store-bought mushrooms
When selecting mushrooms, look for those with white fuzzy stuff (mycelium) near the base. Cut the stem butts and place them in a jar with used coffee grounds. Alternatively, you can wrap the stem butts in wet cardboard and put them in a Ziploc bag, storing them in the fridge. After a few weeks, the mycelium will have taken over the coffee grounds or cardboard. At this point, you can transfer the mycelium to pasteurized straw.
Using a petri dish
A petri dish containing mushroom mycelium can be sealed and stored in the refrigerator indefinitely. Small samples from the dish can be introduced to a food source such as sterilized grain or straw. With the correct conditions, you should be able to harvest your own mushrooms in a few weeks.
General care instructions
Maintain a humid environment and a temperature between 65-75°F (18-23°C) for the mycelium to fruit and produce mushrooms. After about two to four weeks, the mycelium should be ready to fruit. Tent plastic over the medium to preserve moisture and allow the fungi to form. In about 19 days, you should be able to harvest your mushrooms.
