How do you prepare the coffee grounds to grow oyster mushrooms?
Hello, and thank you for your comment!
I have been working at growing mushrooms on coffee grounds without any preparation. If you can get them started before they mold, your chances of success are much greater. Storing the grounds outside in the winter keeps the mold down.
There are many options available including pasteurization and sterilization. These options are expensive and labor intensive. I have had the greatest success with mixing fresh coffee grounds and oyster spawn in burlap bags. Moisture content is tricky and the burlap wicks moisture where needed. Oyster mushrooms will out compete mold, but it slows the flush. Good luck and let us know how you do,

Dean, thanks for the information and pictures. I needed a delectable edible mushroom for a story taking place in Montana, and think I have found the one!
Found some Oysters on the river in the Southwest part of the state. Gallatin River. Tried to leave a pic, dont know if it worked. What is the groth rate of wild Oyster mushrooms. We have a few good day of weather before it gets cold again…….is it worth going out again this weekend?
Hey Fisk, glad to hear from you again.
The oysters will flush until the weather gets hot. Then they will rest and flush when it gets cool again. They grow fast and it will be worth your time to go out again. When you know a mushroom is flushing, it is a great time to find new patches. They will come back year after year until the tree is gone. Oysters are great because they are not so dependent on rain to flush because they get their moisture from the tree!

Thanks Dean! Will give it a try this Saturday and Sunday. Is there a way to post picture or send them to you for sharing? Thank you for the web site! Great place to go for answers.
Fisk
Happy to help!
I will set up a way to send pics through the site, but for now you can attach them to my personal email at montanamushrooms@gmail.com and I will post them.
Happy hunting
Dean
Sorry… Any luck with the Oysters?
yep, I posted them on the site! I saw a couple clusters myself, but not where I could pick them!
Hi Dean, no morels yet here in central Montana. Shouldn’t be long. Anyhow I believe I found an oyster this evening but it’s very white-well, cream colored you could say. It has gills and looks like the ones you have pictures of. How can I post a picture for help identifying? Thanks again, Dan
Hello Dan, send the pics to my email montanamushrooms@gmail.com
I will look at at them and help if I can.

We have had no luck in finding Morrels.. But have had some Oysters…Ive heard that you can grow these Oysters in straw? True? I know that moisture is a plus but not sure about the rest. Can I take the spores that I have on a paper towel and start my own Oysters? What about throwing in the whole Mushroom? any Ideas?Robin in Whitehall
Hello Robin,
Whitehall is really dry this year and I have not heard of anyone finding morels yet.
Oysters grow really well on straw. They will grow from spores or pieces of the mushroom. Oysters are very aggressive and start fairly easy. I like to inoculate with everything I have to increase the chances of success. If you get some started now they might flush this fall.
Good luck,
Dean
Thankyou… I’m gonna give her a shot.. Happy Hunting Everyone… Thanxs again
The part where the mushroom is attached to the tree will be the most likely to grow. This is true of most mushrooms.
