Gourmet Shiitake Mushroom Plugs

Our shiitake mushroom plugs enable you to make your own mushroom logs at home! Plug spawn grown at Cascadia Mushrooms are made only with high-quality and vigorous growing strains of shiitake mushroom that fruit in a wide range of temperatures and climates. We include easy-to-follow instructions. Don’t forget the sealing wax!

Each bag of spawn contains 100+ plugs, enough to inoculate 3 to 5 logs that are 3 to 4 feet in length. Once inoculated, the logs must be placed in a shady area exposed to natural rainfall and out of direct summer sun. Mushrooms begin to fruit in one or two years after prolonged soaking. They will continue to produce until the logs rot to the ground (anywhere from 3-7 years!). This is a great garden project and makes an excellent gift for the Do-It-Yourself gardener or homesteader.

Includes easy to follow instructions–requires some tools and sealing wax. Looking for more mushroom plugs? We offer Blue Oyster mushroom plugs too!

I'll know more in 8-18 months

Easy to inoculate plugs into logs. Great instructions, but they are not scheduled to fruit until next year.

This was my first time ordering plugs. They came in great condition and with clear resources for how to inoculate. Cascadia Farms has also done a great job of providing resources via their website for newbies like me. Thank you!

A Shitake Adventure

We drilled, plugged and sealed five oak logs - six actually as we gave one as a gift. Your instructions were easy to follow. Now, we've settled into delayed gratification while we wait a year-plus for our first flush. When our friends supply a few more oak logs, we will order a second species. Thanks so much for your quick service. Anne in Southern Oregon

Plugged the shitake!

Inoculated our oak logs today after letting the antifungal properties of live wood die for a week. Hopefully all are waxed, and the logs are in place. Now we wait! Thank you for all your generous and patient advice 🤣

Shiitake Plug - impressions

Cascadia was very responsive and provided what appears to be a quality product. The plugs were easy to use and we have high hopes. However, I consider any review of recently purchased plugs to be meaningless. The primary issue is whether the plugs result in edible mushrooms one to two years from now. We purchased Shiitake plugs from Cascadia and from MycoUprrhizal in Olympia. One-half of each alderwood log was labeled and impregnated with Cascadia plugs; the other half of each log was impregnated with plugs from MycoUprrhizal. Logs were then put in cradles in five different locations. We'll just wait and see whether our efforts are successful and whether the source of the plugs made a difference.
