No question: the oyster mushroom or oyster mushroom is an extremely tasty and he althy 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. This works perfectly even in your cellar - on straw mixed with coffee grounds.
How to grow oyster mushrooms on coffee grounds?
Oyster mushrooms can be easily grown on coffee grounds mixed with straw by introducing fresh mushroom spawn and storing the substrate at cool temperatures. Mushroom cultivation can produce initial yields after just a few months.
Don’t throw away the coffee grounds
Coffee not only revitalizes 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 he althy 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 optionally hay or a block of sawdust (€22.00 on Amazon)) and of course fresh mushroom spawn. You should always order this immediately before use, as it will no longer be viable if stored for too long. Once all the ingredients are together, oyster mushroom cultivation can begin.
Prepare the 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), and soak the bale of straw in plenty of hot water. After the straw has cooled, mix it with several handfuls of coffee grounds. Use a bale of straw and place the coffee grounds well distributed inside.
Introduce mushroom spawn and grow mushrooms
Prepared in this way, you can now bring in the mushroom spawn. Crumble the broth into small pieces and mix it with the straw and coffee grounds mixture. The straw bale, in turn, can be carefully divided in several places so that you can introduce 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 brood are best kept in a cool, dark basement. You can harvest the first mushrooms after just a few months, but sometimes it can take up to a year and a half.
Tip
Oyster mushrooms can also be grown very well on wood. This has the advantage that you can harvest from it for several years.
