I've never actually tried growing them, but until last winter I lived in an area where we could just walk in the woods behind our house and pick as many morels, bolets, lobster and pine mushrooms as we liked. So there was never any need.

Now that I live in the city, my garden is in a yard which was conditioned with manure and compost from a mushroom-grower's barn. We get the odd feral crop, but they are the ordinary sort that you pick up in most grocery stores, nothing like the tasty ones we could find with a bit of woodcrafting.

I'm interested to hear how the project goes, and especially what your kids make of it. Good luck!
