How to grow King Oyster Mushrooms at Home
You can grow king oyster mushrooms by following the steps mentioned below:
STEP 1 | > First thing is the pasteurization of the substrate. > Cellulose-rich substrate like straw, sugarcane mulch, etc. are the best for the colonization of king oyster mushrooms. > Heat the substrate in water at around 70-75 degree Celsius temperature and keep it in the hot water for 45-60 minutes to kill bacteria. > After leaving from water, put the substrate in a pot and cut it into pieces 1-3 cm in length > After cooling down the substrate to room temperature, put the mushroom spawn into the substrate. Putting spawn into heated temperature will kill the spawn. > Substrate should not be wet but must be damp. |
STEP 2 | > After cooling down, pack the substrate in a mouth-opened container and distribute some of the king oyster mushrooms spawn throughout the straw. > King oyster mushrooms are top-fruiting mushrooms. So, making holes on the side of the growing pots is not required for the colonization of the mushrooms. >The growing container should be kept in a room where direct sunlight does not come. The spawn requires indirect sunlight for their growth into mushrooms. In case of the absence of sunlight, you have to arrange artificial lighting for 8-10 hours a day. >Temperature should remain at 55-65 degrees Fahrenheit. |
STEP 3 | > King Oyster mushrooms are a humidity-loving variety of oyster mushrooms. 85% humidity is required for well-growing king oyster mushrooms. > To keep your growing pots humid, continue to spray some water if required. Make it assured that water should not be dripped. |
STEP 4 | > Pins will start to develop within 7-14 days. > Keep the mushrooms moist by spraying water 2-3 times a day. Be cautious about not using excess water. |
STEP 5 | > Proper harvesting time for king oyster mushrooms is when their caps are flat and fully opened. > When the mushrooms become matured, spores start forming and the edges of caps start to curl down. > After harvesting, mushrooms can be refrigerated in a breathable container. |
STEP 6 | > King oyster mushrooms are single-fruiting mushrooms. >After initial fruiting, the mushroom- blocks should be tossed onto kitchen scrap which in turn can form a good compost. |
Difficulties that you may face Growing King Oyster Mushrooms
Growing king oyster mushrooms can pose some challenges. Let’s take a look at a few difficulties you may encounter and how to overcome them.
Ideal Growing Conditions
To successfully grow king oyster mushrooms, you need to provide them with the right environment. This includes:
- Controlled Weather: King oyster mushrooms require indirect or partial sunlight, a warm temperature of 55-65 degrees Fahrenheit, and 85% humidity.
- Artificial Lighting: If you plan to grow king oyster mushrooms in your kitchen garden or indoors, you’ll need to use artificial lighting to ensure they receive at least 8-10 hours of heat each day.
Contamination Risks
King oyster mushrooms are susceptible to bacterial and viral contamination, especially when exposed to temperatures exceeding 65 degrees Fahrenheit. To prevent contamination, it’s essential to:
- Maintain Ideal Temperature: Ensure the temperature remains within the suitable range to safeguard your mushrooms.
- Practice Good Hygiene: Sterilize and pasteurize the substrate and growing pots, sanitize your hands, and use gloves and masks to minimize the risk of bacterial contamination.
Formation of Excess CO2
During the colonization phase, the production of excess carbon dioxide can negatively impact the growth of king oyster mushrooms. Look out for signs of excess CO2, such as smaller caps and longer, thicker stems. To address this issue:
- Promote Air Circulation: Allow fresh air to freely flow into the growing area, ensuring proper ventilation for your king oyster mushrooms.
Selection of Suitable Growing Pots
As top-fruiting oyster mushrooms, king oyster mushrooms require specific growing pots. Holes in the sides of buckets or plastic bags won’t suffice. Instead, opt for containers with an open mouth, as they provide the best conditions for growing king oyster mushrooms.
By understanding and addressing these challenges, you’ll be better equipped to grow healthy and abundant king oyster mushrooms.
