Why oyster mushroom mycelium fails to fruit for a long time after fully colonizing the substrate, and how to fix it
In oyster mushroom cultivation, you sometimes run into bags or blocks whose mycelium grows very well but, after fully colonizing the substrate, produce no mushrooms for a long time. The main causes and remedies are as follows: 1. The oyster mushroom variety does not match the season. The temperature type of the spawn differs too greatly from the air temperature at cultivation time, which is to say the sowing time was chosen poorly. For example, if a medium-to-low-temperature oyster mushroom spawn is sown at the turn of spring and summer, the mycelium fully colonizes just as the hot season arrives, making fruiting very difficult. Remedy: dig a trench in a shady spot, arrange the bags in it and cover them with soil to oversummer; when the autumn cool arrives and conditions are suitable, dig away the soil cover and carry out fruiting management to reduce losses.
