  I can see some brown spots, so I suspect it's shot-hole cause by bacterial canker, unfortunately:

  I have it on 3 of my plum trees too.
  

  
  
  

  A trowel in the hand is worth a thousand lost under a bush.

  Ok Bob, thanks for your advice. I'll get some wound paste, then prune the affected areas.
