Depending on your conditions, blewit mycelium may be ready to fruit in 6-12 months. The ideal temperature range for this stage is between 40-70 degrees, and blewits need dips into below-freezing temperatures to cue mushroom formation. Often, this naturally happens in the fall after a full season of growing.

Similar to almond agaricus, blewits like a complex material to grow on. Consider making a blend of semi-composted manure, spent mushroom blocks, leaf litter, sawdust, kitchen scraps, grass clippings, cereal straws, and agricultural byproducts like bean hulls, corn stalks, etc. Use materials that are abundant and accessible in your area and avoid anything that’s potentially been sprayed by chemicals.

Recommended substrates: Partially composted yard waste such as hardwood leaves, grass clippings, twigs and tree bark. Composted mixtures of manure and straw or agricultural byproducts.

If you don’t plan to use your blewit mushroom sawdust spawn right away, store in the refrigerator. Use within 6 months of receipt.

Once cultivated, the blewit mushroom has a full flavor that is evoked with thorough cooking. We recommend you use its sweet mild flavor as a compliment to autumn soups. Blewit mushrooms work best when sautéing and simmering, and are delicious in stews, omelets or fried in butter.

CAUTION: Be careful to properly identify these mushrooms when harvesting and before consuming. There are some poisonous purple mushrooms that can grow in similar habitats. Spore prints can be very helpful in distinguishing them from Cortinarius species of concern.

All our spawn is made using organic cultures from our own culture bank. Our sawdust spawn is handmade from a blend of locally sourced, all-natural, organic, and non-GMO woods and supplements from farms and forests in New England and North America.

If you’re going to consume home-grown mushrooms, make sure to cook your fresh mushrooms thoroughly with heat. If it is your first time eating this species, it is best to start with a small amount to check for allergies, even if cooked.
