Shiitake can be grown on many hardwood logs. Oak is the tree Shiitake's traditionally grown on. Willow and Poplar are probably the 2 most commonly used in NZ and are relatively common here. They will grow well on Cherry,Apple,Oak,Maple,Birch. Angiosperms or trees that have flowers are hardwoods and many of them are ideal for Shiitake production. Many NZ native hardwoods like Tawa can also be used. Gum is a very good candidate for Shiitake cultivation and very common.
