I have an old growth japanese methley plum (prunus salicina) which I think has fire blight or some other disease causing defoliation. I don't know much about fruit trees, so I am hoping someone can lead me in the right direction. It hasn't produced ANY fruit this year (usually the ground is covered in plums) it barely bloomed because 3/4 of the crown is now dead wood. These pictures are from about a month ago, it has died back more since. At first the leaves act like they are turning color (as in fall color) then they shrivel up and turn dark brown/black and do not fall off the branches. Their is also some jelly-like stuff that gets on the branches (it is like drops of it) that ranges in color from orange-clear. It stays jelly-like until it dries and hardens. I hope I provided enough info here are the pictures.

This Year's Blooms:

I really want to save this tree, I value it for it's ornamental appeal. I don't like the fruit but the flowers bloom at the same time as callery pear and their fragrance drowns out the fishy smell coming from the neighbor's tree. I will try anything, but I do not have money to spend. Thanks!
