Your Questions About Gardening

GardenersCardiff answers:

It is a difficult process – and it is illegal.

There are books and websites on growing mushrooms. It is possible, but difficult to get them started.

GardenersCardiff answers:

Presuming you are asking how mushrooms are grown commerically for supply to either restaurants or supermarkets, because as the others have pointed out, restaurants don’t usually grow their own produce and supermarkets definitely don’t.

I have been to a commercial mushroom farm. They are grown indoors in darkened barns in trays which are stacked in racks right to the ceiling, all at different stages of growth. The growing medium of the particular place I went to was a combination of straw and horse dung (yes that’s right). The mushroom spore is placed into the growing medium and left under strictly controlled lighting, temperature and moisture conditions. Once the tray reaches the right size,they are packaged and sent to market where they are purchased by restaurant chefs, small supermarkets, etc or they are sent under contract direct to the larger supermarket chains.

Mushrooms, regardless of what kind, is considered exotic to me. 🙂

Basically, you can grow any mushroom you like to grow. Provided that you give them the nutrients for them to feast on.

For starters, try the “easiest” one : Oyster Mushrooms.
Just google it and you’ll find a lot of ways to grow it.
