Developing Log-Grown Specialty Mushroom Production Systems 

Project Description:  

In the eastern U.S. log-grown specialty mushrooms are a common and lucrative practice farmers engage in to diversify operations and create supplemental income.  WSU Extension agents are working on adapting these systems to a Pacific Northwest climate and selection on native tree species to use as substrate, with a focus on shiitake production.  Field trials are examining how to mitigate moisture loss in the log during our dry summers, determining strains best suited for the climate, and tree species that provide the greatest yields.  Research results will be shared in workshops, webinars, instructional videos, and publications.

This project is funded by the WSU BIOAg Program and Western SARE.
