Please advise me on my plum tree which has not fruited this year and the
leaves have holes in them?

The plum tree on our allotments hasn't fruited this year either and only one
of our 4 cherries, the later flowered one, had a decent crop. I believe it
was because there were no insects about when they flowered they they didn't
get pollinated.
