I have been inoculating christmas trees with edible mushroom mycelium.
I used Phoenix Fir Oyster mushroom mycelium on softwood dowels.
Tools required were a drill, 5/16 inch bit and a mallet.
If you visit www.fungi.com you can see some of the products I've used.
The dowels are under the name "Plug Spawn."
In a normal garden setting in Bermuda, I got results at almost exactly
the same time I inoculated in the previous year (in other words, time
till fruiting was about 1 year), and I didn't do anything except spray
water once in a while and cover the logs with some burlap (a.k.a.
Nice use of a throw-away resource.
By my own example I hoped to become a living refutation to the cult of
anointed expertise which has poisoned every aspect of our liberties.
Time we were done with this thing.
This was once a land where every sane person knew how to build a
shelter, grow food, and entertain one another.
Now we have been rendered permanent children. It's the architects of
forced schooling who are responsible for that.
