Applying your mushroom dowels is a simple process, but should be done with proper precaution, safety equipment and care. Using an 8mm drill, drill to a depth of between 5-6cm into your log. When placing multiple plugs, ensure a spacing of 10-15 cm between holes to allow for optimal growth. To prevent competing organisms from entering the hole and to retain moisture, we would recommend applying a natural food grade wax sealant to the plug entrance.
