Spawn stabilization and spreading conditions are the most important things in cultivating oak-mushrooms. For the spreading of hypha, the logs' withered condition, humidity content, and temperature are important. The most suitable temperature is within 22~25¡É. The logs should be withered at the same speed as the oak-mushroom hypha growing in the forward area. Since the logs' suitable humidity content is 38-42%, the logs should be dried. In addition, the humidity of the environment is also important. It is best to maintain a humidity level of 80-90% to breed the hypha. Since light intensity is not important for growth, it is helpful to set up shading.
Oak-mushrooms pass thru the vegetable growth stage and reproductive growth stage repeatedly. From the influences of temperature, humidity, light, and nourishment, they form fruit-bodies. A fluctuating temperature is better than a constant temperature in forming primordium. Roughly 7-17¡É is suitable. Since the oak-mushroom forms its fruit-body under the circumstances of fluctuating temperature, it is most successfully revived when the daily temperature differential is 8-10¡É.
The oak-mushroom fungi (Lentinus edodes) uses the constituents between the epidermis and the woody part of the log as the primary base of its development. It then gradually spreads to the woody part and changes the log, growing hyphae within the log. Since the heartwood is full of phenol compound, the oak-mushroom fungi can hardly utilize the nutrients in the heartwood of the log. The most appropriate wood for the cultivation of the oak-mushroom carries a large amount of sapwood instead of heartwood and has an epidermis that does not wear off easily. Also, since there is no damage caused by various germs or vermin, the life span is relatively long. Once inoculated, the harvest can be extended for a long period of time.

Pure, superior spawn with a high rate of stabilization and strong adaptability should be inoculated before they become over-mature. The spawn must be stored in a cold and dark place with favorable ventilation. The temperature should be kept below 10¡É and humidity in the range of 60-70%. The time of inoculation should be adjusted according to temperature.

The mushrooms can be picked 7-8 days after development, but this varies according to type. Mushrooms that are going to be sold fresh are picked when the caps are 50-60% open, 60-70% for those that are to be dried. Regular sized and good quality mushrooms can be collected once a day.
