Snow oyster (Pleurotus ostreatus) -- also called "winter oyster" -- is a popular firm oyster variety. They have sweeter flavor and aroma than other oysters and hold their shape and texture when cooked. (The taste of snow oyster mushrooms is very mild, and some even describe it as slightly woody and earthy.)

Snow oyster mushrooms are a great mushroom for beginners. They colonize quickly and are reliable producers. They are also a cold weather-loving strain that tends to fruit in the cooler months.

Recommended use:

  • Snow oyster sawdust spawn can be used for log projects and/or outdoor bed, container, and bucket projects.
  • Snow oyster sawdust spawn must combined with a substrate (like straw) or used in log inoculation in order to fruit.
  • If growing on logs, one bag of sawdust spawn will reliably inoculate 20 logs.

Upon receiving your spawn:

Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!

Tools you'll need

To grow on logs using sawdust spawn, you will need a Log Inoculation Tool, Log Sealing Wax, and Wax Daubers. 

For larger log projects you may also want to purchase an Angle Grinder Adapter and specialized 12mm drill bit.

Inoculation

Logs:

Snow oyster works well with the log, stump, and totem methods. Colonization is fast and should start producing in 4-12 months. They fruit best in the spring and fall and prefer softer hardwoods such as poplar and aspen, though they will also work on maple.

Outdoor beds:

Storing

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

Cooking

Snow Oysters can easily replace button mushrooms in most recipes and pair well with many cuisines and flavors. Like all oyster mushrooms, they retain water and may develop a viscous texture when undercooked. If you prefer a firm or dryer texture, continue to cook them until their liquid has reduced and cooked off and they begin to brown.

Ingredients

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. 

Cautions & considerations

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.

Sawdust Spawn Frequently Asked Questions

Sawdust spawn is sterilized sawdust colonized with mushroom mycelium. It’s used to inoculate a growing substrate such as logs, wood chips, or outdoor garden beds to start mushroom growth.

It serves as the "seed" for your mushroom crop — transferring live, growing mycelium into your chosen growing medium.

Sawdust spawn is best for outdoor projects like logs, stumps, or garden beds and is slower to contaminate.
Grain spawn is ideal for indoor grows or bulk substrate inoculation because it colonizes faster but is more contamination-sensitive.

Sawdust spawn is mixed or packed into a substrate (like logs or wood chips) to inoculate it. Common methods include:

  • Drilling and filling holes in logs
  • Layering in outdoor wood chip or straw beds
  • Mixing with sterilized sawdust or wood pellets for bag cultivation

Most sawdust spawn performs best on hardwoods like oak, maple, or beech. Some species (like Wine Cap or certain Oysters) can tolerate small amounts of softwood in the mix.
