Mushroom Compost

Mushroom compost from Spokane’s Happy Mountain Mushrooms!  Mushroom compost is a chunky mix of fully myceliated sawdust, bran, coffee grounds, and brewer’s grains.

Apply to soil in the fall or spring.  Mix into the top few inches of your garden soil for added nutrients, water and nutrient retention, and added organic matter.  Don’t be surprised when you see some mushrooms popping up later!
