We are currently in the process of updating our directories for companies that provide spawn and other cultivation supplies, as well as farmers, loggers, arborists, etc who are interested in supplying fresh cut logs for shiitake cultivation.
These directories are being expanded to the NORTHEAST US, including Connecticut, Delaware, Massachusetts, Maryland, Maine, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, West Virginia, and Washington, D.C.
Add a listing to the supplier directory: email email@example.com with contact information.

One need for aspiring shiitake mushroom growers is to source sustainably harvested small diameter logs, known as “bolts,” for production. Bolts need to be free of defects and scarring on the bark, and are usually around 4 – 8” in diameter and about 36” long. Suitable species include Oak, Sugar Maple, Beech, and several others.
