Some people we know had a friend that was knowledgable in fungi and he is still in hospital and the rest of the people that ate the bad mushrooms need transplants!!! Nooooo, not a chance I would rather buy them!!! My brother said he used to collect rose hips and get paid for them but that was years ago!!! A lot of young leaves can be used for salads and they are nice, I got fed up with different bags on dog walks, we also collect stuff for our chickens as they cleared thier big bit of garden!!! Pluss I have a load of nettles ready for beer in the freezer....
Our tree surgeon said he takes anything thats free and so do I, our whole house is pre owned and most of my wardrobe is, we get some great stuff for min £
