How to Grow Mushrooms From Old Mushroom Stem Butts
Usually, when it comes to growing mushrooms, the most important thing you should start with is the mushroom spawn; This is what mushrooms grow from, so it is an essential ingredient. Without it, it would be like trying to grow an apple tree without the apple nugget, it will never work. Usually the mushroom spawn will be specially created by a mycologist, and will usually consist of some type of grain that has been impregnated with mushroom mycelium (the mycelium is what the mushrooms come from).
You can create your own mushroom spawn in several ways, but what most people do not realize is that you can actually grow your own mushrooms from the old stalks, which allows you to reuse mushrooms old and start your own cycle of mushroom cultivation.
All you need to do is cut a small section of the mushroom stem, no bigger than one inch in length. It is important to try and use the lower part of the stem, with the bulbous part of the stem intact (this part is usually removed before preparing the mushroom for cooking and for packaging before selling it in stores). However, if you have already grown some of your own fungi of some kind of spawn, then you will have no problem getting the healthiest variety of stem butts. You can still try to use the stem of mushrooms brought from the store, but you may not be as successful.
It is important to note that not all mushrooms have this capacity for stem growth, and there are only a few varieties that are known to be able to regenerate their stems. These include oyster mushrooms (Pleutrous Ostreatus), parasol mushrooms, morels, prince and many more.
All you need to do is remove a section of the stock from the stem and get some corrugated cardboard. Soak the cardboard and then try to peel it in half, so that the paper is as thin as possible. Next, place the carboard on a surface and place some of the cylinder heads on the top. Try to leave about 6 inches of cardboard per end of the stem. Cover the stems with the rest of the corrugated cardboard and then soak again for a few minutes. Place the folded cardboard pieces in an old box: cardboard, wood or anything else that keeps the box moist, and then place it in a shaded position in your garden before covering it with leaves.
What will happen is that the mycelium will begin to grow through the pieces of cardboard, from the stock of the stem, using the cardboard materials as food (the mushrooms grow naturally in the wood, so the cardboard it is ideal to use and it is easier to decompose it). After a few months, you will have your own cardboard spawn, and you can use it to grow mushrooms in more cardboard, or you can mix this cardboard spawn with straw, creating an outdoor bed or mushroom patch, or you can try to transfer the spawn. to other substrates.
