 Pleurotus ostreatus

White Oyster is one of the most popular mushrooms to grow at home. Its slight anise flavor pairs well with seafood and is delicious on its own lightly sauteed with olive oil and finished with a squeeze of lemon juice. Heavy fruiter good for most hardwood types.

These seemingly innocent small pieces of wood are carrying a secret. They have been inoculated with pure mushroom mycelium and when inserted into a log or stump can provide a delicious surprise. Consider these plugs the seed of mushroom and turn your yard into a forager's delight. (5 Oz Package, contains 100 plugs)

Ideal wood type: Oak, Maple, Beech, Birch, Alder, Elm, Poplar, Cottonwood, Ash, Willow, Box Elder, Hackberry, or Mulberry
Do NOT use: Cedar, Redwood, Cypress, Fruit Trees, or Conifers ~section~Mushroom Log Plugging Instructions

Log Selection:

Logs must be cut from healthy living trees. NO ROT AT ALL! Plugging your logs must take place zero to two months from the date that the tree was felled, but the sooner the better. Best time of the year to cut is winter into spring when the trees are completely dormant.  However, you can inoculate at any time during the winter months.  Keep the bark undamaged and as intact as possible.  Keep the logs clean and off the ground by stacking on a crate or scraps of wood.

Log Type:

Suitable wood species:  White Oak, Red Oak, Sweetgum, Ironwood, Maple, Tulip Poplar, River Birch, Cherry, Black Gum, and Honey Locust. In general, oak is THE best for most mushroom varieties. NO black locust, apple, cedar, or Osage Orange. Hemlock will work for reishi and possibly shiitake, provided that it is fresh and free of rot. We highly recommend running all oysters on softer hardwoods like tulip poplar, and saving your oak for other species.

Log Prep:

Soak your logs for 12-24 hours AFTER plugging with spawn. This means starting the soaking immediately after plugging (and sealing) them.  Note:  if the logs are less than a ten days old, soaking is not necessary.

Log Drilling:

Drill holes starting two inches from the end of the log and spacing six to eight inches apart.  Make the rows of holes three to four inches apart along the girth of each log.  For example, a four inch diameter log will have three rows of holes in a line, with each hole in the line six inches apart. Use 5/16 inch bit for plug spawn. Drill the holes 1 1/4 inch deep.  Once all the holes that you drilled have been inoculated with, wax over with melted bees or soy wax immediately. Also wax over the ends of the logs, anywhere the bark was nicked or damaged, and anywhere that branches were cut off of the log.

Log Storage:

Stack criss-cross in full shade during the colonization period, preferably off the ground (a pallet works well for this). Keep your logs in full shade in a place with access to water.  Keep your logs outside in the elements and do not cover them. Let the rain fall on them.

DO NOT ALLOW THE LOGS TO DRY OUT! However, it is not necessary to soak the logs during the colonization period, unless it is exceedingly dry (If you do not receive rain at least once every 2 weeks, you will need to water your logs).  If necessary, a deep soaking is best.  This means 12-24 hours of rain, sprinkler, soaker hose or roll them into a stream, pond, kiddie pool, barrel, bath tub, watering trough, etc.  Note:  The chlorine in municipal water will not hurt the logs.  Make sure the bark dries out between soakings.  Remember, fewer deeper soakings are best.


Spawn Run:

Takes anywhere from four months to two years, depending on mushroom and wood species. For example-Oyster on poplar- four-six months. Shiitake on White oak –at least 12 months. Be patient…. keep your logs hydrated and they will eventually make mushrooms.  Look for the ends of the logs to turn white with mycelium after a soaking rain as a sign that the spawn run is nearly complete.  At this point, you can force your logs to fruit by soaking them for 24 hrs.  If the weather conditions are right for the species that you are cultivating they will fruit naturally on their own.  If you continuously force fruit your logs they will not last as long.

Special notes:  Providing shade.  North side of house (but not under the eaves, as it needs the rain) is excellent.  A simple piece of 80 percent shade cloth draped over the logs works well.  Or under the cover of bushes, evergreen trees, etc.

The logs will get lighter in weight over time as the fungus eats the lignin and cellulose and converts it into mushrooms.  Eventually they will fall apart and be recycled into the earth.  A six inch white oak log inoculated with shiitake will produce for five to six years.  You can expect roughly a year of production per inch of diameter of log for oak, less for softer hardwoods like poplar.

Of course, never consume a mushroom that you haven't positively identified!
