Dowels can be ‘inoculated’ (injected) with edible mushroom spores. These spores spread along the grain of the wood, turning the dowels into seeds that can be ‘planted’ into a log.
Holes are drilled all over the log.
Treated dowels are inserted, then covered over with hot wax.
The log is then left in a shady area under trees or shrubs for a few months, until the spores grow through the log.
Eventually, the fungi will ‘flower’, and can then be picked and eaten. More mushrooms may then grow back in their place.
