Growing Shiitake Mushrooms in an Agroforestry Practice
Cultivating shiitake mushrooms represents an opportunity to utilize healthy low-grade and smalldiameter trees thinned from woodlots as well as healthy branch-wood cut from the tops of harvested saw-timber trees. When the mushrooms are collected and marketed, the result is a relatively short-term payback for long-term management of wooded areas.
The cultivation of shiitake mushrooms on solid wood requires a significant amount of shade and wind protection, but not a significant amount of acreage. Therefore it is an excellent opportunity for landowners with smaller acreages to utilize forested or shaded areas. Shiitake producers can often obtain wood for cultivation from land management agencies or private landowners. In addition to making productive use of woodlots and forested acres, logs that have been used for shiitake production, called “spent” logs, can be ground and recycled as compost (see page 12 for Kimmons and others, 2003) or used as a fuel and heat source for winter mushroom production.
Shiitake mushrooms can be grown indoors or outdoors on almost any deciduous wood that retains its bark for a number of years. When shiitake are cultivated outdoors on logs in a managed shade environment, a forest farming practice is initiated.
