what is wrong with my plum tree?
my plum tree had lots of blossom this year, and it looked healthy, and after the blossom faded it looked as if it would be covered in bunches of plums. then the leaves started to crinkle up,some of the developing plums became deformed, grew very quickly into what looked like pods and rotted away. now most of the plums which are left are nearly all getting lumpy bits on them, and don't look right. such a shame because over the past few years the plums have been healthy and taste delicious. does anyone know what is wrong, and what i can do to help get the tree back to normal. i don't know much about fruit trees, so any advice would be gratefully received
