Hello all - A new poster to the ArbTalk forum here. I am generally speaking a forest manager, but have been asked to look at some Wild cherries in the garden of a neighbour as a favour. The leaves on said cherries have been "curling up and dying" - my first thought was bacterial canker but they had not seen any resin bleeding or oozing so had to rethink that one. There are some 9-10 trees in their garden infected, with a small Rowan close up underneath one of the said trees also showing some signs of an infection. Some pictures here: view of the whole tree: It seems so far from the reading I have done on this website and elsewhere it is not bacterial canker or any environmental factors, such as poor drainage or soil conditions. The only thing I can seem to find which matches is something called leaf spot - link to RHS site here The only advice for treatment of this condition seems to be to remove as much foliage as possible to reduce pathogen / inocculum levels and to possibly treat the tree with a copper fungicide to limit the spread. Does anybody have experiences with this or similar diseases, and can you advise on the effectiveness of above treatments? Any advice or differing diagnoses much welcomed. many thanks, Luke Edit - the links to pictures above appear to be broken - can anyone suggest where to post images to make it easy to share them online? Many thanks
