Chaga (Inonotus Obliquus) is a parasitic fungus that mainly grows on birch trees.
The mushroom is often called the king of medicinal fungi and has been used as a medicinal fungus in Asia for thousands of years.

The Sami also have a long tradition of using chaga for medical purposes.

Chaga is a quite rare mushroom as it does not spread so easily in a natural way. Because of this, it can be exported at a fairly expensive price.

In Finland, there has been a lot research in recent years on the cultivation of chaga and methods that make it possible to cultivate chaga have been developed.
The prospects for cultivated chaga are bright and the market potential is enormous.

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.

Protective vax is included with all Chaga dowels.

The best time of the year to inoculate Chaga is between May-October.
If you want the dowels to be delivered at a specific time. Please notify us about it in the order message.

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

When inoculating birch trees with chaga dowels we recommend using 4-5 dowels per tree. Place the dowels at approximately 50 cm intervals.


Chaga can be grown by inoculating live birch trees with dowels that live chaga mycelium grows on.
The inoculation works best on young trees with a diameter of between 15 – 25 cm.
The best time for inoculation is between May – October.

Here’s what you need:
* Birch trees with a diameter between 15 – 25 cm.
* Wooden dowels (plugs) inoculated with Chaga mycelium
* A wooden drill
* A hammer
* Protective wax (e.g. beeswax or graft wax)


Drill a hole in the birch tree about 40 cm from the ground with a clean drill.

Drill a new hole about 50 – 60 cm higher up on the tree than the last hole and repeat the process until you don’t reach any higher up the tree.

We recommend bringing a chair so that it is easier to reach higher up. (4-5 dowels per tree is a suitable amount)


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


Hit the Chaga 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 dowels with protective wax so that no other fungi or bacteria can attack the tree through the hole.

Mark the tree you’ve inoculated with color so that it is easy to find again.


Now the waiting begins.

After the inoculation of the mycelium dowels, it takes up to 3 years before the “lump” of chaga begins to grow.

You can expect the first harvest within 5-8 years.
After the first harvest, you can get several smaller harvests from the same tree.
However, the harvest will be smaller and smaller as the nutrition in the tree runs out.

When the nutrition in the tree has run out, you can cut it down and use it as firewood.
