King oyster mushroom dowels (plug spawn) for inoculation of logs or stumps

Growing mushrooms on logs or stump is a fun project for people interested in gardening.
It is not particularly costly or time-consuming to get started. Check the instructions further down.

Our mycelium dowels for mushrooms are excellent for cultivation throughout Europe.
The mycelium plugs are manufactured in our laboratory, which is adjacent to our mushroom farm in Österhankmo.

Our mycelium plugs are manufactured to order and delivered directly from our laboratory. So that they are as fresh as possible upon delivery.
We recommend using the plugs as quickly as possible after delivery.

Delivery time varies but usually around 2-3 weeks after ordering.

Mycelium plugs should be stored in unopened bag in the refrigerator until inoculation.

When inoculating logs with mushroom dowels you usually use around 50 dowels per meter log. With the smallest dowel package you can inoculate 5 meter of logs.


Most mushrooms that we sell mycelium dowels of do not grow very well on coniferous trees.
Therefore, we recommend that you use logs of hardwood trees.

When plugging the logs, we recommend using relatively recently chopped trees (1-3 weeks from being felled is okay). Cut the chopped trees into as large pieces as you can handle.

We recommend cutting up in lengths of between 50-100 cm. Keep the bark intact!

Older logs that are drier can be used but then we recommend that you put them in a water bath overnight first.

How long it takes until you can expect your first harvest varies depending on the mushroom species and the diameter of the log. The larger the logs, the longer it takes. But for most species it takes between 9- 12 months.

After the first harvest has arrived, the logs provide mushrooms continuously for years as long as you take care of the log.

Here’s what you need:
* Logs of hardwood trees with a diameter between 15 – 25 cm. The bark on the logs should be intact.
* Mushroom dowels (or plugs) with mycelium of the desired mushroom variety.
* A wooden drill
* A hammer
* Protective wax (e.g. beeswax or graft wax)


Drill holes in the log at about 10 cm apart.
The holes should be as deep as the dowels.

Rotate the log and make a new row of holes about 10 cm from the previous row.
Feel free to put the first hole in the new row between the first two holes in the previous row.

Continue drilling holes until you get all the way around the log


Insert the mycelium dowels into the holes that you have drilled.


Hit the mycelium dowels all the way into in the holes you drilled with a hammer. The end of the dowels should be flush with the bark.


Cover the end of the dowels with protective wax.
If there are damage in the bark of the log, it may be useful to also cover the damage with protective wax.

Do not cover the ends of the log with protective wax.


Mark the logs with mushroom type and date when they were plugged.

Place the logs outside in a shaded place. We recommend placing them horisontally.
The logs should not be in direct contact with the ground.

When the first mushrooms start growing you can stand the logs up.


Now the easy part is done. If you want go enjoy good harvest from your logs you need to care for them.

The most common mistake people do is letting the logs dry out.
Take note the weight of the logs after they have been inoculated.

If the logs are noticeably lighter when you try lifting them, it's time to water them.

You can hydrate the logs by submerging them into water for a few hours.
You can aslo hose them down. But if you use a hose you have to be patient.
Because it takes some time for the logs to soak up water.
