Description

“Cold temperature range” sawdust spawn kits for shiitake cultivation on logs.

“Cold range” indicates the conditions under which this strain can be fruited, and are NOT an indication of which type of climate they grow best.  Fruiting Temperatures: ~7-20C (44-68C).  This strain of shiitake will expand your season by fruiting earlier in the spring and extending later in fall than the wide range variety. Does not respond well to forced fruiting in summer.

Shiitake Lentinula edodes, are a gourmet edible mushroom long revered in Asia.  Growing shiitake on hardwood logs is easy, but takes patience as it can take up to a year, even two, before your logs are ready to fruit for the first time.  These delicious mushrooms are well worth the wait, and once colonized your logs will produce a few crops every year over several years.

There are two ways you can inoculate logs with sawdust spawn.  The first requires chopping up a freshly fallen hardwood log into rounds and stacking a few on top of each other with a 1/4″ layer of sawdust spawn in between.  See video for more info.

The second way requires a special inoculation tool.  Drill holes about 25mm (1″) deep into freshly harvested hardwood log using 12mm drill bit with depth stop..  You can use a regular drill, however a special adapter can convert and angle grinder to a high speed drill.  Insert plug spawn into holes with inoculation tool, then cover with melted wax using a dauber.   Store logs outdoors in shade, and soak periodically during extended dry periods.  After 6 months to 2 years your log will be ready to produce mushrooms.  For detailed instructions watch videos on our Learn to Grow page.

Once your log is fully colonized, you can force fruit it in the spring, summer and fall, by soaking in cold water and keeping very wet for a week. When conditions are right, shiitake can also fruit naturally (without forcing) in late spring and in early fall.
