sick plum tree
I have a mature plum tree which is not looking very well. The trunk of the bifurcates about 6 inches above the ground. We have lived here for 5 years and one half of the tree has always looked "dead" and is covered in ivy. The other half however has seemed healthy and produced a lot of fruit. This year it produced a fair number of flowers but now the leaves are curling and dry and brown and it has only produced about half a dozen plums. We are in the west of Scotland and it has been pretty wet this year. Any advice would be very welcome.
