Many of the ripening plums on my tree have been withering - discoloured (pale and mottled) and shrivelled, lengthening until they almost resemble laburnum pods. Yet their neighbours appear fine. The symptoms don't fit those of any disease of plum trees that I can find online.

Any ideas for what's causing this and how to treat/stop it? This was the first good crop the tree's had for some years.

Try Taphrina pruni,

Thanks. Aside from the mention of swelling on one side (which I haven't seen in dozens of affected fruits), the Wikipedia description of this sounded very much like the problem I've got. The RHS (whose site I finally remembered to check specifically) only called this 'pocket plum' - confusingly different from the American 'plum pockets' apparently caused by Taphrina communis. Clearly it's a developing science!

Hi, did you find a treatment for this? I think I have the same problem.

Already? It's much earlier in the year than I found it happening to my plum tree....

I cut off all the affected twigs etc, in hopes of preventing any spread to previously unaffected fruit, but didn't have much fruit in the end. Hoping for better luck this year, since the blossom has been quite lush and we haven't had high winds etc to knock it down.

You could check Wikipedia and the RHS site information about this in case there are any chemical treatments which, as an organic gardener, I wouldn't have tried.

Thanks for that. Appreciate the update. Our plum trees are huge (as tall as the house) so it's not going to be possible for me to cut off the branches etc. so I have no idea what I'm going to do... Good luck this year!
