Shiitake appendix & resources

Shiitake (Lentinus edodes) is native to Asia and is found growing wild in the mountainous

regions of China, Japan, Indonesia, and Taiwan. Records of mushroom cultivation date

back around 2000 years. 'Wu san Kwung , who is credited with working out how to grow

shiitake mushrooms in China around the year 1000, is commemorated with an annual feast

day, and temples throughout the country are dedicated to his achievements' Merlin

Sheldrake -Entangled Life.

 

In nature, Shiitake spores are released from fruiting bodies in the autumn or spring,

traveling through the forest they fall on trees, fallen branches and logs. The Shiitake spores

take over the wood and build a mycelial network that produces fruiting bodies.

 

Cultivation involves using a substrate which is the growing medium where the mushrooms

first establish themselves as mycelium and use the substrate as a food source to produce

their fruiting bodies. Shiitake can either be grown on fresh cut logs or a sawdust block.

Fresh cut logs after innoculating with spores take about a year to fruit but the log will

continue to fruit biannually or more for three to four years.

 

Sawdust blocks are relatively easy and much quicker than using natural logs taking about 3

months to fruit. and produce about 4 flushes with a short rest between each one. The yield is high but a few argue the earthy taste is slightly less than shiitake grown on a log.

Commercially this is becoming the preferred method.

Mushroom grow kits

If the process of spawning your own substrate is a step too far for you, but you really want a

harvest of fresh shiitake, you could always start with a simple grow kit prepared by a

mushroom specialty company. One of the best companies I know is Merryhill Mushrooms
