DIY – Grow Your Own Gourmet Mushrooms

“Don’t eat a mushroom unless you’re certain it’s an edible species!”

Mushrooms are a delicacy in many restaurants and kitchen tables.  From Shiitake to Morels to the common button mushrooms found in grocery stores. 

They can be grown at home and used fresh in food preparations and appetizers.

I have many fond memories of mushroom hunting with my grandpa out in the woods.

Sometimes we were fortunate enough to find some mushrooms and other times it was just a good walk in the woods.

One way to increase your success at having mushrooms available for your recipes is to grow them yourself.

Spores can be purchased and started in wood or straw as a medium. 

With wood, a core is cut out for each patch of spores and the spores are placed in the wood that has been soaked, generally a 4” oak tree that has been cut and cured.

The only problem is that it can take a year or so to have the tree cured enough for this purpose.

Straw works well but you have to be sure of where the straw came from so you don’t have problems with pesticides and herbicides.

Wood and straw also present a problem of having competing mold spores.

Kits can work really well and sometimes not!

If you are a DIY type person and would like to recycle some coffee grounds, then to get started round up about 5 ½ pounds of fresh coffee grounds.

Generally, you can get this from a coffee shop or restaurant, where they end up just throwing them away.

I would suggest starting with growing Oyster mushrooms since they can be one of the easiest to grow.

Order the spawn that you will need, about a pound of spawn or 17 ½ ounces.

This will give a good ratio of spawn to coffee grounds.

Next is to purchase if you don’t have on hand some freezer bags about ½ gallon size.

Cut a few small slits about ¼” for air to get in.

To keep from contaminating the spawn and coffee grounds, be sure to wash your hands with soap and water, then mix the spawn and coffee grounds together.

Place the bag in a warm (64-77 degree) dark place.

During the next three weeks, you should see the mycelium start to grow across the coffee medium.

After about three weeks the whole bag should be completely white. If you see any green that is competing mold, remove.

If the mixture turns green you will have to start over and try again.

Place the bag of mycelium in a spot with fresh air and a little light such as a North facing windowsill.

Be sure to keep the bag moist by misting. In about a week you will see little mushrooms growing.

They will double in size every day.  When the edge of the caps begins to turn upward, that indicates when harvest time is ready.

Cut at the base and use it for cooking or just eating!

Quick Tip


Wild mushrooms: What to eat, what to avoid
“Don’t guess,” advises Tradd Cotter, who has been cultivating mushrooms for more than 20 years

  1. Join a local mycological (fungi) group. They are located all over the United States. A list is available at the North American Mycological Association.
  2. Buy a regional field guide to learn what mushrooms grow wild near you.
  3. Seek to identify at least the genus of the mushroom you have found (identification keys include the stem, a spore print, what the mushroom is growing on and the structure of the stem base, which could be below ground).
  4. Take two collecting baskets when foraging. Put mushrooms positively identified as edible in one. Put mushrooms you are uncertain about in the other. You won’t get sick by simply touching a toxic mushroom, he said.
  5. Be extremely careful if you are a pet owner and want to take your dog on a foraging trip. Dogs lead the list as victims of deadly and poisonous mushrooms — more than any other animal or humans, Cotter said.
