It looks like one of my tom plants has got blight - yellowing leaves with black spots, flowers dying before fruit have a chance to form. I know I should pick off affected leaves but am worried about my other plants. Is it contagious and if so should I get rid of the plant completely before it affects the others ?(They are in a separate area of the garden from this one).
There are some tiny, cute toadstool shaped mushrooms growing in the growbag underneath also!
