Whoops! Sorry Keith but this is not actually the same thread I started! I
made the mistake because the title you used is the same as the one I used!

I apologise but hope what I said helps you. It's the same problem, in a way.

Maybe not a proper gardening question but a lot of the potatoes we buy in
the supermarkets just now ,turn green.The green appears to be only on the
peel but I have read somewhere that green potatoes can be poisonous.Has
anyone in the group noticed this and also should we be worried ??
