I have a fruit tree guild around a plumb tree. It fruited for the first time last year, so I was really excited for this year. Unfortunately it's not looking so good. The leaves are withering, some branches don't have them at all, though there does seem to be some branches doing ok. The Internet said to scrape some bark away and if it's brown instead of green it's probably dying, so I did that in a few spots and it seems fine.

The technical info you might want to know:

This is the tree's 4th year

I live in zone 6a

I pruned it in the beginning of February

Any advice would be greatly appreciated
