Grow Mushrooms on Logs and Stumps
For those of you with patience and access to fresh cut logs from conifer or hardwood trees or stumps such as alder, oak, birch or cottonwood, you can grow lots of mushrooms at home. Mushrooms grown from dowels are very winter hardy and can be grown throughout most of the nation. Using our “dowel plug spawn” you can inoculate logs or stumps with mushroom cultures. It is important that the logs are freshly cut, and the bark in good condition. It is best to cut the logs in late winter or early spring before the buds break and leaves appear. A 4-6" diameter and 4 foot length is convenient, but not essential, stumps and odd sized pieces can also work. Using a 5/16 drill bit, drill holes about 1.5" deep and space them 5 or 6" apart. A 4' log will need about 30 or more dowels. More will result in faster colonization and perhaps quicker production. Hammer a plug in each hole and seal with paraffin or a compound like Doc Farwell’s Tree Heal. (See page 88) The logs are then stacked in a shady location where moisture can be maintained. Mushrooms should begin to appear in from 6 months to 2 years and will continue to appear on the logs for several years. Softer woods like alder or cottonwood will produce fewer mushrooms than denser woods like oak, but may start sooner. Or use dowels in stumps. Full directions are provided!
