Has anyone had or have a patio pot grown cherry tree, i brought this specaily for the patio has i didnt want it getting too big but this summer & last years summer it lost its leaves early and what looked like sap laeaking out of tiny holes all over the bark. I looked at every cm of it & couldnt find any pest of any kind, I moved it into shade incase it was getting too much sun but it didnt seem to help, then some branches started to die back. I still got fruit of it but its not looking very healthy & am now worried it might not make it through the winter.
Any suggestions on how to save my cherry tree??
