Lentinula edodes: Shiitake mushrooms are relatively easy to grow, and they like the South African winter months, when the day and night-time temperatures are fairly extreme. Having said that, we have grown shiitake well in our summer months, in a frequently watered tunnel (just leaving the hose pipe to run, until the ground is soaked and has about 10mm of water on the surface), airing the tunnel in the early morning or evening. They are grown on logs using shiitake plugs, but they do well on sawdust and other substrates too. We mix our shiitake spawn into a substrate.
Our Shiitake growing from an ‘artificial’ grow log. The artificial part is the plastic that holds the substrate together.
