Log Care Tips

A mushroom log is a living organism. It has a mood and a cycle and needs attention once in a while.

If you own a log and are having trouble getting it to bloom, check out our FAQs for help.

Shiitake mycelia cells work by replacing the cells of the log with its own cells, creating fungi inside the log during the dry and warmer seasons as well as outside the log (in the form of mushrooms) during the colder, wetter seasons. This process requires water, air, and light to work.

Logs should be kept somewhere with natural light, but not direct sun. They can be kept inside in areas that are at room temperature and normal to high humidity, or they can be left outside in a shaded garden for Spring and Fall for fruiting and brought inside for Winter and Summer. Don’t keep them in cool, dry, or dark places like a garage or basement. Remember: Water, air, and light are all essential.
You should soak the log once every two weeks with chemical-free, room-temperature water to keep the mycelia cells producing. Use bottled water, rainwater, or natural well water. Soaking the log at this regular interval will keep it strong and healthy and will produce large crops the longer you own the log.


Every couple of months you can force the log to bloom, or fruit, by shocking it and tricking it into thinking it’s the wet season again. Soak the log for about 24 hours in cold water (preferably ice water) and the log will soon begin to produce its tasty mushrooms. After the log blooms we recommend letting it rest for 6-10 weeks so the mycelia cells can re-build and prepare for another fruiting.
