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, blue oysters 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.
Recommended use:
- Blue oyster sawdust spawn can be used for log projects and/or outdoor bed, container, and bucket projects.
- Blue 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 up to 20 logs. (You can calculate how much you'll need here.)
Blue Oyster log chart:
| BEST WOOD SPECIES* | Aspen, Cottonwood, Tuliptree, Willow |

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!

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.

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.
*Wood recommendations are based on our own testing. You may have different results experimenting with other wood species.

Excellent production!
I made my first mushroom beds with these. Despite not being an expert and making a few mistakes these started producing today, just 3 months after I made the bed. I thought for sure my chickens were ruining it as they liked to dig holes in the wood chips and soak up the cool moisture underneath. Not the case!

They’re popping now!
So easy, my first bucket grow. Used chopped straw from local feed straw. I was concerned at first because the straw was so full of seed that it looked like I had planted a lawn in the bucket. But this spawn is so aggressive that it didn’t seem to matter. Fully colonized the 5gal bucket at 2 weeks, and started pinning beginning of week 3. So fun!

2 recent purchases - Wine Cap and Oyster Mushrooms
Great purchasing experience. They both came packaged perfectly, I planted them that day, and we had mushrooms starting after three days. We highly recommend North Spore and will be ordering more varieties!
