Blue Oyster (Pleurotus ostreatus) is a fast substrate colonizer with a strong bluish-gray hue. It produces richly umami mushrooms with a soft, meaty texture that pairs well with most dishes. Oyster mushrooms are great for beginners because they colonize quickly and are reliable producers. As our most productive oyster strain, they are reliable, cold-tolerant, and fruit prolifically in early spring or late fall. They are also ideal for commercial cultivation, especially when grown on straw.
Blue oyster sawdust spawn can be used for log projects and/or outdoor beds and containers.
Sawdust spawn is ideal for larger log projects of 10 or more logs.
-
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.

Logs:
Blue oyster mushrooms work well with the log, stump, and totem methods. Colonization is fast and may start producing in 4-12 months, though fruiting is dependent on environmental triggers. They fruit best in the spring and fall and prefer softer hardwoods such as poplar and aspen. They will also work on maple.

- 2-4 months (outdoor beds and containers)
- 4-12 months (logs, stumps, and totems)

If you don't plan to use your blue oyster sawdust spawn immediately, you can refrigerate it for up to 6 months.
-
Blue oyster mushrooms 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 under-cooked. If you prefer a firm or dryer texture, continue to cook Oysters until their liquid has reduced and cooked off and they begin to brown.
-
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.

Growing Great in Salt Lake!
Started two mushroom beds outdoors for the first time this past May, both Blue Oyster and Wine Cap and the oysters were far and away the winners! I made a roughly 3x3 ft bed with chopped straw, about 6inches thick. I soaked the straw for a few hours when I built the bed, and sandwiched the sawdust spawn with the straw. Being in a very arid climate, I was unsure how it would go, but I kept some burlap coffee sacks on top to help maintain moisture, and angled my garden sprinkler to hit the bed 2-3 times a week. After no natural rain for about two months, a storm came through in July and I had my first flush! Over the past 4 months I have had 1-2 flushes a month, with about a half pound each time! Can't wait to see if/how they overwinter. Will definitely be growing these in the garden again.

Blue Oysters in Minnesota
North Spore has been so patient & helpful in answering my myriad questions. I set up my first mushroom beds late in the spring (late April/ early May) & our first flush came in on 07/01 - and from that, we harvested about 1.5 lbs. Then, we got another flush a couple weeks later on 07/14 and again harvested about 1 lb. It's funny, it seems like natural rainfall triggers these flushes. I can't wait to see if we get any more this summer. I followed the instructions on how to set up an outdoor bed (used hay + oak pellets) & watered religiously. Great use of the shady areas in our yard and I'm especially excited to keep these beds fed year after year as perennials, if you will. :)

Great Spawn
Great looking spawn as always from North Spore. Inoculated a couple of days ago and already healthy colonization. Very excited to see how this works out, off to an amazing start.

Great product
I have bought many sawdust spawn kits over the past couple years and they have all performed great. I got the blue oyster spawn and the bag was beautifully colonized with mycelium. Stored it for a week or so in the fridge till I got my bed set up. Once I added it to my bed it completely took off! Judging by the growth I should see a few mushrooms by the fall and then a great harvest by spring. If you are looking for a easy product to use that is aggressive and forgiving this is the one for you. The picture I added was a quick check on colonization only one week after I added the mycelium.

Purchased the bag of spawn after having fun with the boxes and am now attempting to grow a bigger outdoor crop. North Spore does a great job with video's and on-line support staff to explain all your questions. It has now been 3 weeks and awaiting blast-off. I live on Long Island and set up two separate area's to determine the best location for future attempts. Me and my daughter are now into mushroom growing. She is doing Reishi for medicinal purposes. I'll follow-up with a report once the they get going.
