Good breeding success is achieved on a standard recipe for wood decomposers. Especially important is the structure of the substrate, it must be loose-fluffy and can breathe well. Use not only very fine, but also medium-fine sawdust, preferably from beech. Hedgehog spiny beards, like oyster mushrooms, can go into fruiting immediately after colonizing the substrate, they do not need a ripening period.
Hedgehogs are considered to be cheeky and hasty and sometimes fruit completely uncontrollably. Sometimes already on the petri dish, in the brood or on only partially colonized final substrate. Or even in complete darkness. They are very sensitive to too high CO² levels and sometimes even switch back to vegetation mode during fruiting. A cloudy aerial mycelium without substance sometimes develops if CO² levels exceed a critical mark for a longer period of time.
Aim for only single fruiting bodies on the substrate, better leave the culture only a few fruiting windows, ideally only pinpricks in places where primordial growth is already visible, instead of exposing them extensively.
Hericium erinaceus are obtained when the fungus can fructify hanging from the side. Then please weigh down the crop with a weight in time to prevent it from falling over. When fruiting upwards they get spherical mushrooms with beautiful curls, real “pom-poms” or “monkey heads”. Do not let the hedgehogs sit too long on the substrate, such fruiting bodies often taste bitter. For this reason, a rapid course of culture is advantageous.
In China, for the cultivation of Hericium erinaceus, containers made of plastic or glass are used. Sawdust, waste paper, rice straw, corncobs, sugarcane and cotton waste are used as growing medium. Additions of bran, gypsum or sucrose are common; wheat bran in particular results in vigorous and fast-growing mycelia. Green mold (Trichoderma) is a hazard with age. Permethrin treatment after fungus gnat infestation is not recommended, as the insecticide is deposited in the fungus in high quantities.. The mycelium grows best in an acidic pH range between 4 and 5.5.
