Hi,

I have a three year old "Jublieum" plum.

Its reasonably healthy (I think), though ive had to chop a branch off because of bacterial canker.

It has only produced about three plums, (to be expected being so young).
but...these fruits have a strange, clear, plastic like, thread coming out of them, its not sweet to the taste (not sure whether tasting was a good idea but i wanted exclude crystalline sugar). The fruits are a good shape and are developing well.

Is this a natural or pathological process?

Thanks for your guidance

Ed
