Shiitake Mushroom FAQs:

  • Why are my shiitake blocks browning? 
    • The browning of a shiitake block is known as "barking over". Because, unlike logs, blocks do not have bark, the mushroom needs to grow a layer that will act as a moisture-retaining layer.
  • How long can I store my shiitake mushroom blocks before I set them up?
    • If you keep the blocks refrigerated, they can be stored for up to one month. However, mushroom growth is stimulated by movement in shipping, so be prepared to see several mushrooms start to grow even if the blocks stay dormant.
  • When are shiitake mushrooms ready to harvest?
    • Typically, shiitakes are ready to harvest in 10 days, plus or minus a few days depending on fruiting conditions. Harvest when the gills are visible, but the caps are still curled under. This blog provides some visuals: When are my shiitake ready to harvest?
