Need Help With European Plum Tree

[Eric]

I don't know if my Early Laxton plum has Silver Leaf, False Silver Leaf, or something else.
The discoloration on the leaves is lavender/light purple colored.

It has aphids and possible spider mites on the leaves as well.

I would appreciation any help.

Thanks for your time,

Eric.

Here are some photos:

Welcome to the forum Eric! Sorry to hear you've been having issues with your plum tree, hopefully someone here will be able to help identify the issue.

Welcome Eric. It does look like silver leaf but to prove the point and stop it spreading try cutting back or removing the affected branches. If the inside of the branch has a dark stain then it is almost certainly silver leaf so continue to cut back until the wood becomes clear. If it is still there when you've reached the trunk of the tree then it is likely the whole tree is infected and it should be removed and destroyed by burning if possible. Sadly there is no cure for it.

OK, thanks for the help.

Do I prune now, or should I wait until next Summer?

You can prune now, if it is silver leaf then it will stop or restrict it spreading through the whole tree.
