We spent one early spring day last year with our neighbors and my dad, drilling holes into logs for shiitake mushroom logs. With a hammer its easy to tap the spore-laden dowel pieces into the holes. Our neighbor’s five year old took to this job well and hammered in lots of dowel pieces. We each took home some logs, watered them each week for a bit, and kept them in a shady spot. This summer, after a good rain, we got a nice crop of shiitakes from the logs. You can get the spores and all the instructional details from The Mushroom People.
