If you have a shaded, damp corner in your garden where nothing will grow this would be an ideal place to grow some rather special mushrooms. Have a look at this site for further details: Gourmet Mushrooms
I will be ordering my own kits in a couple of weeks, if anyone is interested in buying kits for themselves let me know, and we could pool the order for possible discounts and savings on postage.
There is a good article starting on page 36 in "Teagasc Today's Farm" March/April issue regarding a farmer in Co Limerick who has started to grow these very same mushrooms commercially in his own forest. You can read this at Today's Farm March/April 2012
