Joanna ordered mushroom spore laced dowels from the local farm cooperative. Yesterday the kids and I got the dowels "planted." First, Sam dug a trench behind the shed. We lined it with plastic so that it would hold water, and set up the water spout to empty into it. I drilled holes in logs and Sam and Emma pounded the dowels into the holes. Finally we set up the logs in the trench. With luck, mushrooms should appear in a few months, and the logs should last a few years.
