A lot of leaves on one branch of my Vicoria plum are turning yellow. I can't take a pic for a couple of days since my daughter's taken the camera on a school trip to Paris. Is this sone disease - and if so what - or is it just the effect of the drought? So far, the plums look fine.
Not had this myself. On the symptoms you describe, there is an RHS link:

It's possible that it's bacterial canker too.
With just one branch, it doesn't sound like a water problem.
I'll keep a close eye on it then; if everything on the branch dies off, I'll cut it off quick before it spreads. Thanks.
