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!

Retail orders are typically shipped within three business days of purchase (likely sooner). We ship products out Monday – Thursday. Anything purchased after 4pm PST Thursday will be shipped the following Monday. Please note that overnight and/or expedited shipping times refer to the time something takes to ship according to the shipping method, rather than the time it takes to send an order.

If a package is returned due to an incorrect address provided during the checkout, we reserve the right to charge additional shipping. Requests for shipping information can be sent to info@cascadiamushrooms.com.

We send out orders as soon as possible. Please keep in mind that any mushroom kits or spawn will need to be protected from extreme cold and heat. Mycelium (the base of the mushrooms) is alive and should not be left out in the sun or snow. Please be ready to accept your order as it arrives.

What are the key ingredients to growing mushrooms successfully?

High humidity, indirect light, a good amount of fresh air, and temperatures ranging from 55-75 degrees F. For more information, check out our page on growing mushrooms.

When should I start my mushroom kit?

All mushroom kits should be started within a week of receiving them. If you can't start your kit right away it can be safely refrigerated for up to 4 weeks.

Nice Plugs

We were very happy with the service and the product we got from Cascade Mushrooms! Can’t wait to see (and eat) the results!

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!

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
