No question: The oyster mushroom or oyster mushroom is an extremely tasty and healthy edible mushroom that can be used in many ways in the kitchen. So that you can enjoy it all year round, simply grow it yourself. It even works well in your cellar - on straw mixed with coffee grounds.
Coffee grounds are a good fertilizer for oyster mushrooms
Don't throw away the coffee grounds!
Coffee not only invigorates tired people, but is also an excellent fertilizer for indoor and garden plants. The drink contains many valuable trace elements, but also phosphorus, potassium and nitrogen - everything plants need for healthy growth. It is best to use dried coffee grounds for fertilization. This is also ideal for growing tasty mushrooms such as oyster mushrooms.
Growing oyster mushrooms in coffee grounds
For this project you will of course need coffee grounds and straw (or alternatively hay or a block of sawdust) and of course fresh mushroom spawn. You should always order these immediately before use, as they are no longer viable if they have been stored for too long. Once all the ingredients are together, the oyster mushroom cultivation can begin.
Prepare substrate
First of all, prepare the substrate. To do this, either take a whole bale of straw or cut individual straws into pieces about ten centimeters long. Boil the small pieces of straw in plenty of water (which you can then use to fertilize the vegetable garden), soak the straw bale with plenty of hot water. After the straw has cooled, mix it up with several handfuls of coffee grounds. Use a bale of straw and place the coffee grounds evenly distributed inside.
Bring in mushroom spawn and grow mushrooms
Prepared in this way, you can now bring in the mushroom spawn. Crumble the brood into small pieces and mix with the straw and coffee grounds mixture. The straw bale, in turn, can be carefully divided in several places so that you can bring the mushroom spawn into its interior. Now it's time to wait and see: oyster mushrooms prefer cool temperatures of less than 11 °C, which is why the substrate and spawn are best kept in a cool and dark basement room. You can harvest the first mushrooms after just a few months, but sometimes it can take up to a year and a half.
tips
Oyster mushrooms can also be grown very well on wood. This has the advantage that you can harvest it for several years.
