Dowel spawn is a wood dowel that has the mushroom mycelium growing inside it. It is used to inoculate dead tree stumps or logs. After drilling a hole in a log and tapping a dowel into it, the mushroom mycelium will grow from the dowel into the surrounding wood. Dowels are 5/16" diameter X 1" long. Most of the mushroom varieties grow best on newly cut hardwood or semi-hardwoods. A list of commonly used wood is included. (Most cannot be grown on conifers, including Pine, Fir, Cypress, Juniper, Cedar, Redwood and Eucalyptus.) Dowels can be refrigerated for many weeks until used. Use 1-2 dowels per foot of log to be inoculated for best success. Inoculate only one type of mushroom on each log. Instructions on how to use them come with each packet.
