• Containers: If growing indoors, you’ll need containers or bags for your substrate. These should be clean and have the ability to allow air exchange while retaining moisture.
• Tools for preparation: This includes a shovel or spade for outdoor beds, and a large pot for pasteurizing substrate if growing indoors.
• Water source: A spray bottle for misting or a garden hose with a fine spray setting will be necessary to maintain moisture levels.

Preparing the Substrate

The substrate is the growing medium for your mushrooms and plays a crucial role in their development. For Wood Blewits, a rich, organic substrate is key.

• Outdoor beds: Layer your chosen spot with cardboard to suppress weeds, then build your substrate layers with hardwood chips, straw, and compost. The cardboard will also retain moisture and attract mycelium.
• Indoor containers: Mix your substrate (such as pasteurised straw or hardwood pellets) with water until it’s moist but not soggy. Sterilise or pasteurize the substrate to kill off any unwanted bacteria or fungi, then cool before inoculating with spawn.

Creating the Ideal Environment

Once your space is selected and your supplies are gathered, focus on creating the ideal conditions for your Wood Blewits to thrive:

• Moisture: Keep the substrate consistently moist but not soggy. Use a spray bottle for indoor containers or a mulch layer outdoors to retain moisture.
