Thank you so much Jonathan for your reply and I understand what you are saying. So, now the next question is, do I prune again in June, or leave it until June 2009? Sorry if I sound a bit dim. Apparently this plum tree is the 'off-spring' of a tree that came from France over 60 years ago and was given to my great uncle. He then grew another tree from one of the plum 'stones' and my tree is a cutting of this! What do you think it's chances are?
