Cultivation of the Yellow Oyster Mushrooms

After selecting a suitable substrate and preparing the spawn, you can cultivate the Yellow Oyster Mushrooms. The best temperature for growing Yellow Oysters is between 21-25°C with high humidity levels of 80-90%. You can use either plastic bags or jars to grow your mushrooms.

For both methods, first assemble all the necessary supplies, which include:

• Spawn for Yellow Oyster Mushroom
• Substrates, such as sawdust or straw
• Plastic bags/jars with lids
• Gloves and a mask to protect yourself from contamination.

Start by filling your substrate into plastic bags or jars. Then add the spawn to the substrate and mix well to distribute the spawn evenly. Close the bag or jar with its lid and make sure it is airtight to keep out any contaminants. Place your bags/jars in a dark, warm location with 80-90% humidity levels. Allow the mushrooms to grow for 14-21 days until they are fully developed and ready to be harvested. When harvesting, handle the mushrooms gently to avoid damage.

After harvesting, you can store the mushrooms in a cool place and enjoy them for up to two weeks. You can also use the mushrooms by drying or preserving them with salt, oil, and vinegar. With proper care and cultivation of Yellow Oyster Mushrooms, you can enjoy fresh and delicious mushrooms in no time.

Harvesting of the Yellow Oyster Mushrooms

The harvesting of the yellow oyster mushrooms begins after 3-4 weeks when the mushroom primordia (button) are formed. The mushrooms should be harvested before they mature and turn into full-sized fruit bodies. Once a week, inspect your growing substrate for signs of mushrooms ready for harvest; when you see the small button mushrooms appear at the edges of the blocks or bags, it is time to harvest.

The mushrooms can be harvested using a sharp knife or scissors. Cut the small mushrooms off at the base and collect them in a paper bag or tray. Remove the substrate undisturbed so new fruit bodies can form, and additional harvests can be made from this same block or bag. When harvesting, wear gloves to protect yourself from the sharp edges of the mushrooms.

Where Do Yellow Oyster Mushrooms Grow? 

Yellow oyster mushrooms are found worldwide, but they thrive best in temperate climates. In North and Central America, yellow oyster mushrooms have been spotted in parts of Canada, the United States, Mexico, Guatemala, and Costa Rica. They can also be found throughout Europe, from Norway to Spain; some countries, such as France, are now taking advantage of their culinary potential. 

In Asia, these mushrooms are present in Japan, Korea, China, and India, while South Africa has its fair share of yellow oyster mushroom colonies. There has even been a report that some have been spotted growing on the slopes of Mt Kilimanjaro! Regardless of where they grow, knowing local laws or regulations concerning foraging and harvesting these mushrooms is still important. Remember to always collect responsibly with caution, respect, and care. 

What is the best way to Store Yellow Oyster Mushrooms?

The best way to store Yellow Oyster Mushrooms is to keep them in the refrigerator. Please place them in a paper or plastic bag with holes punched so air can circulate. The mushrooms should be used within five days of purchase for optimal freshness and flavor.

If you need to store them longer than five days, wrap them loosely in a damp cloth and store them in the refrigerator for up to two weeks. For longer storage, oyster mushrooms can be frozen. Please place them in an airtight container or freezer bag and freeze them for up to six months. Thaw before cooking as you would with any other frozen food item.

Finally, avoid storing yellow oyster mushrooms in plastic bags or containers for long periods, which can cause them to spoil faster. It is also important to store oyster mushrooms away from other vegetables as the strong flavor of the mushrooms may affect the taste of other produce.
