Organic Shiitake Mushroom Sawdust Spawn

I love it. This stuff grows great.

I ordered shiitake spawn about two years ago and finally got my first harvest this spring! It took a while to inoculate, the tree was quite large, but the wait was absolutely worth it. I figure the bigger the log, the longer it will keep producing, so I’m looking forward to many more flushes to come. Very happy with the spawn quality!​​​​​​​​​​​​​​​​

My kids and I had a blast inoculating a bunch of logs with shiitake spawn a few years ago and we do it every year. This has given us pounds of mushrooms to eat and give away. Haven't had any that hadn't grown, although the squirrels seem to like to dig into the spawn in the log. This hasn't stopped the logs from producing more mushrooms than I know what to do with. I would and have recommended North Spore to my friends and they have had great results. Would recommend to others.

The quality of mushroom spawn was fantastic. I was able to harvest mushrooms in about five weeks. That’s gonna depend how you decide to grow it.

These mushrooms are very good. I like them. Everyone must try.

Good, still really figuring the mycology side of things , but hopefully, next year, shitakes.

This bag was huge, and chock-full of mycelium in short order. It was easier than expected to fill the logs. I'd expected that the spawn would have to be rationed, but there was so much I ended up going in search of some stumps to inoculate. So glad I bought here (had a bad experience with some I got on Amazon).

Love growing my own mushrooms
They are so beautiful
And good

I'll call it a labor of love. It was indeed a project, but it was was enjoyable. Logs are starting to produce after just about a year.

A few years ago I ordered North Spore’s shiitake spawn expecting to grow mushrooms. Now I order EVERY spring. What I didn’t expect was to become emotionally attached. These logs are now part of the family. They live rent-free in the shade, eat logs, and produce gourmet-level mushrooms that taste like they’ve been marinated in forest wisdom.

From the first flush, I was hooked. North Spore made the whole process easy—even fun. Clear instructions, solid packaging, and spawn that actually does its job. Mycelium spread faster than gossip in a small town.

Bonus: I now walk around saying things like “these are fruiting beautifully” and “the logs need to be soaked,” which makes me sound like a forest wizard or someone who definitely has their life together.

Would I recommend? Yes. Would I fight a raccoon for the last shiitake on the log? Also yes.

Works good love it

Mushrooms are very good. Everyone should try.

Can’t wait to use, looks like great quality so far and buying experience was excellent.

Can't wait for them to start sprouting!

Fantastic! Shiitake sawdust spore was fun and easy to inoculate. I did 12 logs a mix of beech, oak, and maple Nov 2023. Today all the oak and maple are in bloom. Must be a half bushel of shiitake today. Next time I do this I’ll skip the beech and double the logs to do 24 because the package could have gone that easily.

Excellent. Took a while to get it but all is good.

New to growing, has worked well for me

Products arrived and are well made. I cannot wait to get this project going.

Excellent, works as designed

We had a lot of fun harvesting logs and inoculating them with friends at our homestead. Then last summers weather made them go bonkers and we had logs fruiting in a steady stream for weeks at a time! We are expanding our log set up and plan to bring in more friends and family to spread the productive fun around!

Well inoculated when arrived.

Awesome product

Spawn was in good condition

Amazing!!!

Received bag that was damaged in transit. Customer service was very helpful in sending out a replacement bag.
Inoculated logs and waiting to see results!

Haven't used yet,but the spawn I bought last year has produced a few nice ones I would suggest bird netting, nothing is worse than losing half a crop to birds. Lesson learned!!!

Over a year after innocultating several oak logs , I've had several huge flushes after rainy weather. Nothing like no effort results!

I'm continually impressed with the quality of spawn from North Spore and will continue to go to them first for my mushroom growing needs.

I purchased the shiitake sawdust spawn and used the totem method. The wood is sweet gum that fell in a storm in late January. The wood was green, measuring 12 inches around by 32 inches tall. I cut several layers of wood and stacked as shown in the videos North Spore provided.
The first shiitake mushrooms appeared about 6 months later.
the logs were kept damp but they would not produce again. I thought the endeavor was lost and began to ignore them.
This spring, about one year later, the logs were again covered in mushrooms.
Now they produce every time it rains. The attached photo was taken two days after a big rainstorm and 18 months after the totem was set.
Im curious of how long this set up can produce.

The first flush of shiitake mushrooms appeared about 6 months later. Unfortunately I was traveling and they were too mature for use.

I’m looking forward to trying other varieties of mushrooms if I can acquire additional logs.

Worked great, so I bought again
